Really great explanation of the various adapters, thank you so much! I don't even have an R series camera, just the original 5D DSLR which is becoming hard to use, but was wondering whether to sell all my cherished EF lenses and now I see I don't have to.
Learned something new about these adapters. I don't remember anyone else saying that the adapter also had the rubber seal to keep the weather sealing from the lens. That's good to know.
Glad the video could help! The backside of the adapter looks identical to the backside of an L-series lens. I'm not sure if third party adapters also include this or not, but it's a nice added touch from Canon!
so glad there is this. It will enable me to get the cheaper used Ef 24-70 mm 2.8 lens for my new mirrorless. Huge massive relief! still a bit more than getting the f4 lens but 2.8 is so much better
Thanks for the detailed explanation on this! I have a Rebel T7 and starting to outgrow it already after a year of use, thinking of moving to an R50 but my budget doesn’t call for getting another set of lens again, haha!
hi cody, a very informative vid (: i was considering the R6 mk ii, but came across your review on the R. now, im seriously thinking of getting the R after using the 6D for a decade !
Hi Sam! I'm happy my video could answer some questions for you! It all comes down to what suits your needs best, both cameras come loaded with specs and features, but the R is a very capable camera nonetheless!
I upgraded to a R6mkII and purchased both a Canon EF-RF adapter and a Meike EF-RF NVD. I purchased the one with the VND when shooting video because it is more convenient to adjust exposure via the VND on the adapter vs filters on the end of the lens.
@TeddyCavachon Does the usage of this adapter hinder any R6mkII functionalities like IBIS etc? Am asking about the Camera functions, not the lens functions.. Could you please let me know, Thank you.
Thanks for this Cody, I'm starting to do research into upgrading from my 5d Mkiii to an R5, and was worrying about if I can use all my lenses or not. One question I have is if you ever thought the adapter acts like an extension tube, since those are just empty tubes too. I understand that the extension tube doesn't have the adapter functionality, but i wonder if the adapter could cause any f/stop differences by not allowing as much light to the sensor like a tube would.
I’m surprised at how small your channel is! Greta video. I’ve just traded my 6D in for the R and I look forward to getting it soon. Managed to get an adapter for £70 :D
Love your vlogs Cody , they’ve really helped as I’m also a 80 d user but would like a mirrorless canon ..keep up the great work as it’s really helping me .Thank you x
You’re a hero for responding to everyone’s questions. We appreciate you! I have a EF 24-105mm that was given to me and it’s been sitting in my closet for years because I have a Nikon body. Do you think it’s worth it to get an entry level mirrorless with this adapter JUST so I could use this lens? I’ve been out of the photography game for a while and looking to get back into it.
First and foremost this is just my option, but yes I would say if you are interested in getting back into it and have an EF 24-105, then yeah you can find mirrorless bodies for pretty cheap now. The 24-105 is a great range to have as it covers a lot of bases in photography. If I was to talk to you further about it, I’d ask what kind of Nikon setup you have (assuming you still have it). It depends what you are trying to do, but if you have that lens already it would be worth it to get a body to use it for since a lens is roughly half the cost! Hope this helps and I appreciate the kind words. Let me know if you have any further questions about this or anything else!
Thank you so much. Your video was exactly what I needed! I upgraded to the R6 which arrived the day before I had 4 football teams scheduled just to find out my existing lenses weren't compatible. 😢 They're rescheduled now but I wasn't sure if I could use the same lenses with an adaptor or needed to spend thousands on new lenses. You've saved me so much money. Thank you again!
When I use it on my RP, it automatically changes the aspect ratio from full frame to 1.6 crop and the only way to change it back is to switch back to an rf lense. So YES it does introduce crop at least on the RP. :(
@CodyMajeres well now I know what the issue is, thank you :) Perhaps if you do another video on the subject, you could mention that bit of info for others who may not realize it and get frustrated like I did... just a thought
Auto focus was working fine on all of my lens until I changed lens at a game. Then no more auto focus. I finally just purchased a new adapter and all is fine. So I guess the adapter is faulty. It’s only a few months old.
Appreciate it my guy! I think it's one of those features that has potential...if you remember to use it. Most of the time, I don't have one either though so I'm right there with ya!
Hey, such an outstanding video and you’ve gained a dedicated subscriber.. Thank you for the education.. I’ve been hearing that though its possible to adapt a crop sensored lens to a full framed body as you mentioned, but one possible draw back is the loss of Megapixels when camera is set in Crop sensor mode? I know having a Fullframe lens on a Fullframe body will always have its rightful advantages..
I appreciate that! Yes, a crop sensor lens won’t utilize the entire sensor in the camera, so you’ll notice heavy vignetting and you will have a crop of about 1.6x. So a 16mm lens would be more like 25mm. And yes there is a loss of resolution as well. I wouldn’t recommend doing it, however if you do (I understand why it might be necessary) see if you’re camera has APS-C Mode, or if it’s able to switch from “Full” to “1.6x” so that the camera is prepared to be a crop sensor.
@@CodyMajeres your very welcome, and I deeply appreciate you and your expertise good brother 💪🏾💪🏾.. You certainly gave me all the answers I needed.. Appreciate you taking out the time and I surely will keep you updated.
Can you use EF-S lens with RF camera body using this adapter? I know the EF-S lenses cannot be used with the Cannon full-frame bodies, so wanted to make sure this adapter will allow me to use my EF-S lenses with the RF APSC and/or Full Frame bodies. Thank you!
That's a great question. As long as the third-party lens is EF mount, it will attach to your camera and you will be able to use it. Now, I don't know if the control ring will have full functionality with a 3rd party lens. In theory, it should still be able to control everything except for (maybe) the aperture. However, there might just be communication errors between lens and body. I cannot confirm, nor can I find any solid research to say one way or the other, but if it didn't work I would expect there to be more uproar over that! Hope this helps.
This did not answer the question I came here for: Does it matter what order you attach/detach? Per the control ring instructions you put the adapter on the lens, then on the camera. Once the adapter is on the camera am I supposed to remove it to switch EF lenses??
Per the manual, yes. The adapter goes into the lens first, and then camera. This is for safety and legal reasons. Per most people who use the adapter, including myself, I just leave the adapter attached to the camera body and change lenses as normal.
Hi there . I have a R6 mk 2 and bought the basic adapter but it is not giving me focus with a tamron 24-70 and neither with a a canon 70-200 . Don’t know why. There is a firmware upgrade to do ?
You can try firmware updates, lenses and camera bodies have them. You can find the firmware updates on the product pages usually. However, if it’s not the firmware it means it’s a communication error. Make sure the contacts on the adapter and lens are clean and not interfered with any debris. The other question I would have is have you confirmed the lenses work? Are they your lenses from a previous camera that you’ve used, or did you buy those recently as well? I would try the firmware updates (let me know if you need more help finding those) and cleaning contacts first, otherwise if that doesn’t work contact where you bought the adapter as it might be faulty. It’s unfortunate, but it happens.
Thank you! Not to my knowledge unfortunately, only to help old glass work on newer (RF mount) cameras. I wish though! Would be nice to get RF glass without needing to upgrade the body
Do we lose any stop when using the adaptors? For example, we lose stop when using an extension tube, will we face this with the adaptor also? Thank you!
I'm wondering if other people using the EF to RF adapters have a similar issue to me. With every lens I've used with an adapter, when the AF switch is on, you can hear and see the AF motor in the less randomly turning, and even zooming a bit if it is a zoom lens, until the camera is held still in my hand. If the camera is in motion at all, turned on, and the AF is switched on, this happens and really does a number on the battery. Switching the lens to MF when not in use stops this. Is this just an inconvenience in using Canon adapters that can't be avoided? Thanks for any thoughts!
I don't think this issue has to do with the adapter, but more so the AF function. I've had this same issue with my 50mm when I keep it on AF it's constantly searching for focus points (which you can hear and see it, as you mentioned). This really does drain the battery, I feel your pain! There's a few things I can think of that might help: 1. Try changing the AF mode to a different mode, such as 1-point or the square box that you can move around and select an area to focus. This prevents the camera from looking all over the scene for a focal point and narrows it to a much smaller area. This won't completely negate the issue though, it'll just give it a smaller space to search. 2. If your camera allows, set it to only pull focus when you half-press the shutter. This way, it's not searching until you NEED it to. This will negate the issue, however some shooting scenarios it may not be preferred if you need to act fast. 3. This may not be the most optimal, but putting the lens cap back on between shots will stop this from happening (and also further protect your lens!). But again, I realize this is not the best choice 😂 4. Keep it in MF until you want to shoot. This is another not-great option but it will fix the issue. And you will know very quickly when MF is on! I hope this helps, please let me know if you have any futher questions or concerns!
First of all many thanks for this informative video. I have one question. Does this adapter acts as a multifunctional one as to I can use my rf lens also while the adapter is attached? The point is once the adapter is attached, can we use rf lenses also without removing the adapter?
You can’t use RF lenses, you’ll have to remove the adapter to use the RF lenses. Or, alternatively if you have only 1 EF lens you can just leave it attached to the lens. Kind of the same outcome but to answer your question, unfortunately not able to leave it on for RF lenses.
Does using an adapter affect the need for external lighting or changing the camera settings to allow more light in? Like because of the far distance between the lens & the sensor? When shooting macro or in low light
I didn’t see this covered or anyone ask, but I’m upgrading from an 80d w/canon lenses for video. Have you found the stability or any aspects different with the ring and the old Efs lenses?
Great video. I have purchased the Canon EF-R adapter and using the 70-300 IS USM. When attached it seems I lose all of the motor function in the lens. It this to be expected..thanks.
I did some tests and with an EF lens on a RF body you can not shoot high framerate video. Correct me if im wrong, but i tested R8 with Sigma 18-35 and it did not allow me to shoot slow motion.
The lens will not factor into the framerate of which a camera can shoot. Couple of things to try to get high frame rate: 1. Make sure you enable high frame rate video in settings. Some canon cameras have a setting that needs to be enabled. 2. Ensure your memory card can handle the load. V30 cards struggle and sometimes will not write because they can’t keep up with the transfer of video codec. 3. If you successfully capture footage and are reviewing the footage but it’s not slow, that’s because it won’t be slow until post-production. I hope this helps. Let me know if you still have issues with high frame rates! I can dive into it further if this doesn’t help 🙏🏼
Good video! I have also seen some 3rd party adapter with speed booster glass. Do you know if those would still work with EF-S lenses? Just wondering if the back extension of the EF-S lens would interfere with the speed booster glass..
EF-S lenses cannot be boosted (at least on the wide part) as they do not have big enough image circle. Note also that you must have a crop body. If you shoot video and the body has extra crop for the video mode then boosting might be possible.
I am just learning my new R3. I have been using the lens adapter with no problems until the other night. I needed to change lens so I put on the adapter as always, then attached the lens, but couldn’t get out of manual focus on the camera. The lens was set to auto focus, but in settings on camera the only choice I had was manual focus. Any idea what happened? I even reset to factory settings to see if it was something I changed by accident, but still wouldn’t work. When I put the RF lens back on it worked fine in auto focus. Please help! I am a bit of a novice, but can’t find answer in manual or from Google and I really I need to use my other lens. Thank you!
Oh no! I'm sorry you're running into this. Is it fair to assume that when you say "I have been using the lens adapter with no problems until the other night" that included auto-focus. So, during a lens change you randomly lost auto-focus capabilities with your adapter? Also, just to clarify, which adapter do you have?
At first glance you would think so, but unfortunately not. Reason being is that the adapter makes up for the difference in flange distance. For example, if an EF lens were to sit X mm away from the sensor on an EF mount camera body, it would sit Y mm away from the sensor on the RF body without an adapter. When you introduce the adapter it makes it so the EF lens sits X mm away on the RF body, so the same distance away from the sensor as it would be on an EF body, adding zero distance from the sensor. I hope that makes sense, but in short the adapter does not add any distance, it just makes up for distance lost when using EF lenses on RF bodies.
@CodyMajeres thank you. Makes perfect sense. So with a 70-200 and the adapter plus extension tubes, it will look like a telescope to get a closeup of a dragonfly.
Im sorry if this is something youve answered but I have to Ask😂 If I buy the Canon EOS R or RP(do you recomend one before the other for beginners?), and the sigma 24mm f1.4 art for canon, with this adapter will the focal length still be 24mm then? I was going to buy the 6D mark ii, but seeing that it is an older model and heavier, maybe mirrorless is the way to go🤔
Correct, your 24mm will still be 24mm! As for which camera, they are both great. If looking at specs, the EOS R is going to just edge out the RP overall. More focus points, larger megapixel count, etc. If you do any video, the EOS R also is slightly better. However, if you’re priorities are not so much spec related and more size and comfort, the EOS RP is lighter and smaller while still keeping up with the EOS R for the most part! Hope that helps!
I mean it all depends on what the camera being used is. If it's a DSLR, then I would recommend getting used EF lenses. If the new person is on a mirrorless, then I would tell them to see what they can get for used RF lenses, however I wouldn't tell someone who is new to drop a LOT of money. So I'd say get the base adapter and buy some used EF lenses to use with the adapter. RF lenses are new, so they are the most expensive. Because of that, the price of EF lenses will slowly decline and there should be a lot more available as seasoned photographers start transitioning to RF lenses. TL;DR A new person to Canon EF or RF should buy used EF glass and get the adapter if necessary. Won't need an adapter if it's a DSLR.
100% yes, there’s nothing “wrong” with EF lenses. They just aren’t the new, shiny technology and understand they aren’t the lens of the future for Canon. But they are still quality lenses, especially the L-series EF Lenses, and it would be smart to take advantage of the lower prices due to newer technology.
Hey man really appreciate your video, quick question. Would this work for a Canon EOS 6D Mark 2 with a Sigma 18-35 1.8f lens? With no distortion or vignetting?
The adapter in this video is for camera bodies with RF mount for lenses, so it can attach to RF cameras and EF lenses. The 6D II is an EF camera, so depending on the Sigma lens you shouldn’t need an adapter. However, just to cover all bases, the adapter only works one way. You cannot flip it around and use it on EF camera for RF lenses. Hope this helps!
This might be a dumb question, but I just got a Canon R50 and I want to buy an adapter to be able to use EFS 18-135mm lens from my old camera meanwhile I save money for an RF lens. I know my new camera is better quality than my old one, so will using my EFS lens on my R50 essentially make my pictures the same as my old camera? Is it worth using my R50 or should I just stick to my old camera in the meantime? Thank you!
That’s a valid question to have! My personal opinion would be to use the new camera for sure! The EFS lens will not bring down the performance of the camera. If anything, the camera will help the lens shine a little brighter! Of course, the RF lens will have better quality in technical terms. But without looking too deep into anything you won’t see much difference between the two. It’s more how the equipment is used than how new/old it is! You’ll be fine using the new camera with the EFS lens 👍🏼 Happy shooting!
So I actually ran into this too, I personally haven’t found an adapter that lets you use canon lenses on Sony cameras with full functionality. It’ll let you see the image, but I wasn’t able to change aperture or use autofocus. I think I read somewhere that there ARE adapters that let you do this, they are just very expensive. The main issue is canon lenses aren’t made to communicate with Sony cameras and most canon-Sony adapters don’t solve that.
@@CodyMajeresTHANK YOU!! Okay good I thought I was crazy haha, had a Sony for years and love my canon glass. Was never an issue as I was mainly doing video but now that I’m doing more photography not having autofocus has been such a bummer. Think I’m gonna get a Canon R5 I’m not meant for Sony lol
I bought the cheapest camera with good reviews to see if I wanted to get into photography or not. My fear was spending a ton of money and losing interest. I purchased a Canon R50 on sale to give it a shot. I want some cool zoom lenses without paying thousands. I travel a lot and there's some photos I have taken with my phone that I wish I could blow up for home art, so I want to branch out to a real camera. I have the control ring adapter on the way and was going to purchase some used EF lenses on e-bay at a fraction of the cost. Is there any error in my way of thinking?
Not at all! You can get really great results with even the less expensive gear. Learning the proper way to use the gear will always outweigh better specs!
@@CodyMajeres Awesome, thanks for the confirmation! I was going to start with the 50mm "Nifty fifty". I also want a good zoom lens for nature or something capable of taking a picture of the moon. I have lots of research to do lol.
@@QuiresPan 50mm is such a great lens, you can’t go wrong there! As for nature, you could look for something like 70-200. Or like a 24-105. You could look for f/4 to keep the cost down.
It doesn't have to be a Canon lens, but it has to be a Canon EF or Canon EF-S mount. For example, my Tamron lens that is made for a Canon EF mount can be used with my EOS R by using this adapter. So any Canon EF/EF-S lens, or any third-party lens that is made for Canon EF or EF-S mount will be able to be used with the adapter.
It works but if you have a FF body it goes into a crop mode. On some bodies you may disable it but you get huge vignetting. On for example RP you cannot disable it - also you cannot use any aspect ratio but 3:2
The mount does not shift, no. I’ve had the f/0.0 thing before (not with the adapter), and that usually means the lens isn’t connected or isn’t connected properly. I’m assuming that’s due to the mount shifting as you are experiencing. Probably not supposed to be happening!
@@CodyMajeres okay cool I have one I bought off of Amazon and it moves the slightest and that’s when the 0.0 happens it only started to happen when I got my 24-70. I shouldn’t have skimped on the connector and just bought the canon connector. It would stop all my recordings if it shifted and I didn’t realize it till halfway through the day of filming.
In the instructions for the adapter it says that it should be installed on the lens first, then on the camera. Any idea why and if it would be bad or produce some damage if I leave it on the camera and change EF lenses while installed?
Myself and many other people on the internet don’t understand why that is the written way. I always leave mine on the camera and treat it as if it’s just part of the camera. I’m sure they say to do it that way for legal reasons, covering their ass for any one-off mishaps, probably something along the lines of an attachment remaining on the camera causing damage after catching or snagging on something. Since it’s not technically a “part” of the camera, they will recommend to remove when not in use. But like many others, I keep it on 😃
That would be crop factor and the distance is so minimal that it’s not noticeable. Unless you are pixel peeping maybe 🙂 not enough to claim a crop is introduced though.
I have 3 EF lenses one of which is L glass and none of them have that red dot or white square. Exactly where am I supposed to see them? Somewheres on the lens mount flange?
Are they Canon brand? I assume they are since you mentioned L glass, but if any are third party I’m not sure if they’ll have the same marking system. As for Canon, yes the red dot or white square should be on the lens near the mount flange. It’ll still be on the black part of the camera, the side if you will. I’m trying to explain it best I can with words, but if you search Google images for “Canon Lens Red Dot” the second result is from Digital Photography Review and shows a great photo of both the dot and the square. I hope this helps, sorry if I explained it poorly!
@@CodyMajeres The only red dot on my lens is the one that's an index mark and it's on the side of the lens and not on the flange which is what your video seemed to show (bit that it was all that clear to begin with - way out of focus/blurry and poorly lit). All my lenses are Canon.
@@CodyMajeres To clarify - are you talking about the lens index red dot you match up to the red dot on the body for mounting? Your description isn't at all clear.
I don't personally own that adapter, so I can't get as detailed. However, I know Viltrox is used by many as a third party adapter and seems to get the job done just fine. Sorry I can't be more help for your question, but I don't want to talk about a product I've never touched!
Short answer, no. The adapter in this video is for EF lenses and RF camera bodies, meaning the camera body has to have an RF mount. The T6i has an EF mount. To my knowledge they don’t make an adapter for an EF mount to accept RF lenses.
I got an r5c a few days ago, but the adapter won't connect my ef lenses to the body. It works every now and then, but then suddenly it won't detect the lens and I can't change the fstop or shoot anything. Do you have any idea why? I'm guessing the adapter I have is defect maybe. It also freezes the camera when this happens, but when I turn the camera off and remove the mount, leaving only the camera, it works normal again but without the lens.
I'm using the 18-35 EF from Sigma and the 50 mm 1.4 from Sigma. Both of those doens't work. I do have the 10-18 ef from canon which is also behaving weird when using the adapter on the r5c@@CodyMajeres
Hmm...ok. I don't think I have a solution/answer for you but I do have some thoughts and some suggestions! I hope this helps: I'm thinking you maybe have a faulty adapter, as you also said in your comment. However, if you want to try a couple of things before sending it back, I would first check to make sure these lenses are compatible with the R5C. I'm not very familiar with that camera but I do know the R5 and the R5C have a list of lenses that just don't work with them. If you are confident the lenses are compatible, I would next ensure all firmwares are up to date. This includes lens firmwares and camera firmwares, they both have firmware. If the issue remains, I would double check your lenses and the adapter are properly attaching to the camera (listen for that satisfying "click" noise). If something isn't allowing either end to attach properly, don't force it. That could be the issue. Even though I'm sure you've read this a thousand times, I would also note that Canon isn't the most receptive of 3rd Party lenses, however since you state this happens with a Canon lens as well it does seem to be more than just that. I'll leave you with this: It sounds to me like it could just be a faulty device, and I hope that's the case! Based on what you described happens, it sounds like their might be a lack of communication between the lens and the camera that could be being caused by the adapter. But I will note that EF lenses are older and were made for different systems than what we have with these new R series cameras. It's also worth considering that your camera is just too much for these EF lenses and they are just not able to communicate with each other properly (which is why I suggest checking firmwares for sure). I hope this helps at least a little bit and am hopeful that it's just a defect (and that you get a new one soon so you can use your new camera!)
I just purchased this adapter for EOS R... i am unable to mount my 400MM L 5.6F lens. i don't get it... you said that this should be compatible. i nearly broke the mount, what's going on?
What wasn't explained in the video but the adapter makes up for the different distance between the lens mount flange and the sensor. This distance is less in a mirrorless camera than it is in a dslr. That's because you don't have the distance taken up by the mirror box. Hence why mirrorless cameras are smaller and lighter than dslr's.
I would say that’s entirely up to you and what you shoot and what you want to get out of your next lens! I personally don’t have any use for a fisheye but you might!
How far away are we talking? Like infinity? I’ve noticed that happening with my R at 16mm a few times when trying to focus on clouds or things at infinity point. I think for my cases it had more to do with lack of light than anything. Not sure on your specific details if that could be the issue.
QUESTION: I have a generic ef adapter and used an ef 35-80 on my R8. I did a shoot and focus worked and shot a bunch of pics but now they won’t show up on my Mac or canon app. Anyone know what’s going on?
When the card is in your camera, do they show up in the preview mode on your camera? Can you review the images and see them there? If you can see them on your camera, then I would next try to find a windows computer to see if they show up there. It might be an error reading your card on Mac. I’ve never experienced this, so I’m just thinking out loud. Hoping someone is able to provide more insight!
@@CodyMajeres they showed up in the camera screen after I took the picture and when I hit play button to show the person I was shooting. Then I went back to shooting and finished. When I got back home 1hr later all the ones I shot on the ef adapter are all blank black with a question mark ❔ they don’t show up on camera or in MacBook even though the rf lens pics show up automatically I even tried a free data recovery website and it still wouldn’t show them.
Did you by any chance change lenses with the camera still powered on? From what I'm reading, that would have been a way to potentially corrupt the card.
@@CodyMajeres hey Cody. I think it was on actually. Where are you reading about that? Can you reply with a link? If that’s the case then that would be great to know that’s all it was. I have reformatted the card again so I can test and find out.
Yes, the adapter does not affect the ability to shoot video and does not remove any functions of auto focus. So yes, you can shoot video with eye-tracking auto-focus!
From what I've seen, the camera will introduce that vignette, but it's not due to the adapter. Reason I say this, I use the EOS R at work with OUT an adapter, and at 15mm I notice vignetting. I use the older 16-35mm ii WITH the adapter at home and I don't notice the vignette as much as the 15mm.
I’d look into your camera model and if there’s been any issues. The adapter alone will not limit your ability to use burst, so it’s gotta be something else.
I just bought a Canon ef to eos M adapter and a Sigma 24-70mm f2.8 art lens and my camera won't turn on with it. Anyone knows why? It makes a rattling sound.
If you have the EOS M then I believe you have the right adapter. So that makes me think the adapter may be faulty? I don’t think a rattling sound is normal!! 😅 I’d maybe try to return the adapter and get a new one to replace it? That’d be my first action! Good luck!
I just picked up an R7 yesterday and I can (sadly) tell you that no matter what brand of adaptor you buy, you most likely wont be able to use any 3rd party lenses. Just some food for thought.
@@DistractionPhoto If the third party lens is an Canon EF or EF-S mount, yes you can. I use Tamron lenses on my Canon EOS R with the adapter to this day! Edit: Seems that the R7’s are having issues (and potentially others?). Sorry that’s happening, super annoying! Hopefully Canon can come out with a fix for this soon!
@@DistractionPhoto After looking this up, it seems to be an issue on Canon’s part with the R7. The adapter is designed to work with all models, however I’m seeing that the R7’s are having issues with the adapter.
@@CodyMajeres thank you,I think ef to r is only for fullframe, the R10 will be available next week, it's my second camera after the 700d, so I'm a bit new to adapters😁
The EF-RF adapter is to attach EF lens mounts to RF body mounts. The R10 has an RF mount so that is the adapter you want. It won't matter if the lens or camera is crop sensor or full-frame!
@CodyMajeres thank you for the explanation,i get confused because it new to me and the shop tell me to buy ef to m🙏but now i know and will buy ef to rf
No, one side is designed to be connected to an RF mount and the other side is designed to receive an EF mount. So if you flipped it, it would not work as then you would be putting a surface designed to receive a lens against another surface designed to receive a lens and vice versa. There would be no way for it to attach.
You cannot adapt mirrorless lenses to DSLRs as the adapter would have to have negative thickness. RF has flange distance 20 mm and EF 44 mm. An RF lens must be mounted 20 mm from the sensor and a DSLR has a mirror there. The only solution would be some adapter with optical elements and this would change the characteristics (the focal length) significantly or alternatively allow only macro shooting.
@@CodyMajeres Thanks for responding - there are some who say you can remove the plastic ring - but could damage the lens or mirror. Thanks for the great video.
One more note - you are an EXTREMELY talented RUclipsr - I am recommending you keep finding great ideas that excite you and please continue to post more content. You will get subscribers ... I just wanted to send a positive and encouraging note. Just subbed and gave a thumbs-up.
Thank you! I really appreciate that. July into August was real busy for me, but I'm hoping to have a few videos coming real soon with a lot of ideas for some others.
The problem I have here is that I can’t find a single practical reason why going mirrorless is an “upgrade”. It’s a downgrade - and a way for the manufacturers to save money. So my answer to this adapter dilemma was to keep my 5Dii and expensive EF glass - and otherwise kiss Canon goodbye.
Really great explanation of the various adapters, thank you so much! I don't even have an R series camera, just the original 5D DSLR which is becoming hard to use, but was wondering whether to sell all my cherished EF lenses and now I see I don't have to.
Glad the video could help! I was in the same boat and was also happy to keep all of my EF glass 🤓
Learned something new about these adapters. I don't remember anyone else saying that the adapter also had the rubber seal to keep the weather sealing from the lens. That's good to know.
Glad the video could help! The backside of the adapter looks identical to the backside of an L-series lens. I'm not sure if third party adapters also include this or not, but it's a nice added touch from Canon!
Well, that was quite a review! Hope your channel grows fast.
Thanks! Glad it was helpful to you!
so glad there is this. It will enable me to get the cheaper used Ef 24-70 mm 2.8 lens for my new mirrorless. Huge massive relief! still a bit more than getting the f4 lens but 2.8 is so much better
Except I’m starting to lean more towards new . Sharper image . Can get in closer
Thanks for the detailed explanation on this! I have a Rebel T7 and starting to outgrow it already after a year of use, thinking of moving to an R50 but my budget doesn’t call for getting another set of lens again, haha!
I’ve been there! Thankfully this adapter makes that possible 👍🏼
Me too 😂
To the point, tell it as it is. That you did . Excellent video, Man. Thanks
Glad I could provide, appreciate the kind words!
I bought the EF/RF adapter with the control ring. I am going to order a second one, as I have a second Canon mirrorless on order.
hi cody, a very informative vid (:
i was considering the R6 mk ii, but came across your review on the R.
now, im seriously thinking of getting the R after using the 6D for a decade !
Hi Sam! I'm happy my video could answer some questions for you! It all comes down to what suits your needs best, both cameras come loaded with specs and features, but the R is a very capable camera nonetheless!
I upgraded to a R6mkII and purchased both a Canon EF-RF adapter and a Meike EF-RF NVD. I purchased the one with the VND when shooting video because it is more convenient to adjust exposure via the VND on the adapter vs filters on the end of the lens.
Nice! The VND one sounds great!
@TeddyCavachon Does the usage of this adapter hinder any R6mkII functionalities like IBIS etc? Am asking about the Camera functions, not the lens functions.. Could you please let me know, Thank you.
@@suryatejak9815 I have not encountered any hindering of camera functions with either the Canon or Meike adapters.
Thanks for this Cody, I'm starting to do research into upgrading from my 5d Mkiii to an R5, and was worrying about if I can use all my lenses or not. One question I have is if you ever thought the adapter acts like an extension tube, since those are just empty tubes too. I understand that the extension tube doesn't have the adapter functionality, but i wonder if the adapter could cause any f/stop differences by not allowing as much light to the sensor like a tube would.
That’s a really great question. I personally didn’t notice any effects as such, and my f/stops continued to perform as they did prior to the adapter.
I’m surprised at how small your channel is! Greta video. I’ve just traded my 6D in for the R and I look forward to getting it soon. Managed to get an adapter for £70 :D
Nice find on the adapter! Happy shooting, hope you're liking the R so far!
Love your vlogs Cody , they’ve really helped as I’m also a 80 d user but would like a mirrorless canon ..keep up the great work as it’s really helping me .Thank you x
You’re a hero for responding to everyone’s questions. We appreciate you!
I have a EF 24-105mm that was given to me and it’s been sitting in my closet for years because I have a Nikon body. Do you think it’s worth it to get an entry level mirrorless with this adapter JUST so I could use this lens? I’ve been out of the photography game for a while and looking to get back into it.
First and foremost this is just my option, but yes I would say if you are interested in getting back into it and have an EF 24-105, then yeah you can find mirrorless bodies for pretty cheap now. The 24-105 is a great range to have as it covers a lot of bases in photography.
If I was to talk to you further about it, I’d ask what kind of Nikon setup you have (assuming you still have it).
It depends what you are trying to do, but if you have that lens already it would be worth it to get a body to use it for since a lens is roughly half the cost!
Hope this helps and I appreciate the kind words. Let me know if you have any further questions about this or anything else!
Struggling with parting with my EF lenses 2 of which are brand new but this helps .. thank you Cody!!
Bill G.
Thank you so much. Your video was exactly what I needed! I upgraded to the R6 which arrived the day before I had 4 football teams scheduled just to find out my existing lenses weren't compatible. 😢
They're rescheduled now but I wasn't sure if I could use the same lenses with an adaptor or needed to spend thousands on new lenses.
You've saved me so much money. Thank you again!
So glad to hear it was helpful! Thankfully you can use those same lenses 👍🏼🙏🏼
Cody can you test the other RF to EF adapters to see if they work as good as the Canon one because the other adapters are less than half the price .
Is there any specific one(s) you’d like to see compared with?
When I use it on my RP, it automatically changes the aspect ratio from full frame to 1.6 crop and the only way to change it back is to switch back to an rf lense. So YES it does introduce crop at least on the RP. :(
What lens are you using? The adapter itself will not put it into 1.6 crop but if you’re using a lens that’s made for a crop sensor, it will.
@CodyMajeres well now I know what the issue is, thank you :) Perhaps if you do another video on the subject, you could mention that bit of info for others who may not realize it and get frustrated like I did... just a thought
As I was answering this, I was thinking the same thing. Apologies on that, but happy to help clarify!
The ND one sounds like the best thing ever in the world, one filter size for all the lenses no matter the end diameter
Definitely a huge perk! A little expensive, but if you’ve got the budget a good option.
Auto focus was working fine on all of my lens until I changed lens at a game. Then no more auto focus. I finally just purchased a new adapter and all is fine. So I guess the adapter is faulty. It’s only a few months old.
Great video! 👊 I kept it simple and opted for the base, control rings never clicked with me 😉
Appreciate it my guy! I think it's one of those features that has potential...if you remember to use it. Most of the time, I don't have one either though so I'm right there with ya!
Hey, such an outstanding video and you’ve gained a dedicated subscriber.. Thank you for the education.. I’ve been hearing that though its possible to adapt a crop sensored lens to a full framed body as you mentioned, but one possible draw back is the loss of Megapixels when camera is set in Crop sensor mode? I know having a Fullframe lens on a Fullframe body will always have its rightful advantages..
I appreciate that! Yes, a crop sensor lens won’t utilize the entire sensor in the camera, so you’ll notice heavy vignetting and you will have a crop of about 1.6x. So a 16mm lens would be more like 25mm. And yes there is a loss of resolution as well.
I wouldn’t recommend doing it, however if you do (I understand why it might be necessary) see if you’re camera has APS-C Mode, or if it’s able to switch from “Full” to “1.6x” so that the camera is prepared to be a crop sensor.
@@CodyMajeres your very welcome, and I deeply appreciate you and your expertise good brother 💪🏾💪🏾.. You certainly gave me all the answers I needed.. Appreciate you taking out the time and I surely will keep you updated.
Absolutely! Happy to help man 🤘🏼
Can you use EF-S lens with RF camera body using this adapter? I know the EF-S lenses cannot be used with the Cannon full-frame bodies, so wanted to make sure this adapter will allow me to use my EF-S lenses with the RF APSC and/or Full Frame bodies. Thank you!
Yes, you can
Does the Control Ring mount version function with third party lenses? Or does the Control Ring stop working when using non Canon lenses?
That's a great question. As long as the third-party lens is EF mount, it will attach to your camera and you will be able to use it. Now, I don't know if the control ring will have full functionality with a 3rd party lens. In theory, it should still be able to control everything except for (maybe) the aperture. However, there might just be communication errors between lens and body. I cannot confirm, nor can I find any solid research to say one way or the other, but if it didn't work I would expect there to be more uproar over that! Hope this helps.
This did not answer the question I came here for: Does it matter what order you attach/detach? Per the control ring instructions you put the adapter on the lens, then on the camera. Once the adapter is on the camera am I supposed to remove it to switch EF lenses??
Per the manual, yes. The adapter goes into the lens first, and then camera. This is for safety and legal reasons.
Per most people who use the adapter, including myself, I just leave the adapter attached to the camera body and change lenses as normal.
Super informative, thank you so much!
Hi there . I have a R6 mk 2 and bought the basic adapter but it is not giving me focus with a tamron 24-70 and neither with a a canon 70-200 . Don’t know why. There is a firmware upgrade to do ?
You can try firmware updates, lenses and camera bodies have them. You can find the firmware updates on the product pages usually. However, if it’s not the firmware it means it’s a communication error. Make sure the contacts on the adapter and lens are clean and not interfered with any debris.
The other question I would have is have you confirmed the lenses work? Are they your lenses from a previous camera that you’ve used, or did you buy those recently as well?
I would try the firmware updates (let me know if you need more help finding those) and cleaning contacts first, otherwise if that doesn’t work contact where you bought the adapter as it might be faulty. It’s unfortunate, but it happens.
Great video Cody! By chance would you happen to know if there is an adapter to use the RF lens on my EF mount?
Thank you! Not to my knowledge unfortunately, only to help old glass work on newer (RF mount) cameras. I wish though! Would be nice to get RF glass without needing to upgrade the body
@@CodyMajeres Thanks so much for the response. This helps a ton. I appreciate it! 👍
Do we lose any stop when using the adaptors? For example, we lose stop when using an extension tube, will we face this with the adaptor also? Thank you!
No! No loss of stop
so this thing dont decrease any quality ?
No quality decrease!
@@CodyMajeres correct there are no optics in the adapter only electrical contacts so there is no additional glass between your lenses and the sensor
I'm wondering if other people using the EF to RF adapters have a similar issue to me. With every lens I've used with an adapter, when the AF switch is on, you can hear and see the AF motor in the less randomly turning, and even zooming a bit if it is a zoom lens, until the camera is held still in my hand. If the camera is in motion at all, turned on, and the AF is switched on, this happens and really does a number on the battery. Switching the lens to MF when not in use stops this. Is this just an inconvenience in using Canon adapters that can't be avoided? Thanks for any thoughts!
I don't think this issue has to do with the adapter, but more so the AF function. I've had this same issue with my 50mm when I keep it on AF it's constantly searching for focus points (which you can hear and see it, as you mentioned). This really does drain the battery, I feel your pain! There's a few things I can think of that might help:
1. Try changing the AF mode to a different mode, such as 1-point or the square box that you can move around and select an area to focus. This prevents the camera from looking all over the scene for a focal point and narrows it to a much smaller area. This won't completely negate the issue though, it'll just give it a smaller space to search.
2. If your camera allows, set it to only pull focus when you half-press the shutter. This way, it's not searching until you NEED it to. This will negate the issue, however some shooting scenarios it may not be preferred if you need to act fast.
3. This may not be the most optimal, but putting the lens cap back on between shots will stop this from happening (and also further protect your lens!). But again, I realize this is not the best choice 😂
4. Keep it in MF until you want to shoot. This is another not-great option but it will fix the issue. And you will know very quickly when MF is on!
I hope this helps, please let me know if you have any futher questions or concerns!
Go to single shot focus and not servo focus.
Great video man. Very informative 👍
First of all many thanks for this informative video. I have one question. Does this adapter acts as a multifunctional one as to I can use my rf lens also while the adapter is attached? The point is once the adapter is attached, can we use rf lenses also without removing the adapter?
You can’t use RF lenses, you’ll have to remove the adapter to use the RF lenses. Or, alternatively if you have only 1 EF lens you can just leave it attached to the lens. Kind of the same outcome but to answer your question, unfortunately not able to leave it on for RF lenses.
Does using an adapter affect the need for external lighting or changing the camera settings to allow more light in? Like because of the far distance between the lens & the sensor? When shooting macro or in low light
Nope! You’ll hardly notice it once it’s on, from a settings standpoint
simple explanation ....thank you
I didn’t see this covered or anyone ask, but I’m upgrading from an 80d w/canon lenses for video. Have you found the stability or any aspects different with the ring and the old Efs lenses?
I upgraded from the same and did not notice any aspects different with my EF glass! It all performs the same
Great video. I have purchased the Canon EF-R adapter and using the 70-300 IS USM. When attached it seems I lose all of the motor function in the lens. It this to be expected..thanks.
I don’t believe that’s to be expected. You lose auto-focus and stabilization of the lens?
@@CodyMajeres yes, it seems I see the shaky hand symbol. I do get focusing and if I switch to manual focus on lens it registers on camera.
I did some tests and with an EF lens on a RF body you can not shoot high framerate video. Correct me if im wrong, but i tested R8 with Sigma 18-35 and it did not allow me to shoot slow motion.
The lens will not factor into the framerate of which a camera can shoot. Couple of things to try to get high frame rate:
1. Make sure you enable high frame rate video in settings. Some canon cameras have a setting that needs to be enabled.
2. Ensure your memory card can handle the load. V30 cards struggle and sometimes will not write because they can’t keep up with the transfer of video codec.
3. If you successfully capture footage and are reviewing the footage but it’s not slow, that’s because it won’t be slow until post-production.
I hope this helps. Let me know if you still have issues with high frame rates! I can dive into it further if this doesn’t help 🙏🏼
Good video! I have also seen some 3rd party adapter with speed booster glass. Do you know if those would still work with EF-S lenses? Just wondering if the back extension of the EF-S lens would interfere with the speed booster glass..
Can’t say for sure on the third party adapters as I’ve never used one!
EF-S lenses cannot be boosted (at least on the wide part) as they do not have big enough image circle. Note also that you must have a crop body. If you shoot video and the body has extra crop for the video mode then boosting might be possible.
I am just learning my new R3. I have been using the lens adapter with no problems until the other night. I needed to change lens so I put on the adapter as always, then attached the lens, but couldn’t get out of manual focus on the camera. The lens was set to auto focus, but in settings on camera the only choice I had was manual focus. Any idea what happened? I even reset to factory settings to see if it was something I changed by accident, but still wouldn’t work. When I put the RF lens back on it worked fine in auto focus. Please help! I am a bit of a novice, but can’t find answer in manual or from Google and I really I need to use my other lens. Thank you!
Oh no! I'm sorry you're running into this. Is it fair to assume that when you say "I have been using the lens adapter with no problems until the other night" that included auto-focus. So, during a lens change you randomly lost auto-focus capabilities with your adapter?
Also, just to clarify, which adapter do you have?
Hi Cody, do think these adapters also act like macro extensions tubes?
At first glance you would think so, but unfortunately not. Reason being is that the adapter makes up for the difference in flange distance. For example, if an EF lens were to sit X mm away from the sensor on an EF mount camera body, it would sit Y mm away from the sensor on the RF body without an adapter. When you introduce the adapter it makes it so the EF lens sits X mm away on the RF body, so the same distance away from the sensor as it would be on an EF body, adding zero distance from the sensor.
I hope that makes sense, but in short the adapter does not add any distance, it just makes up for distance lost when using EF lenses on RF bodies.
@CodyMajeres thank you. Makes perfect sense. So with a 70-200 and the adapter plus extension tubes, it will look like a telescope to get a closeup of a dragonfly.
Will the Lightroom Classic recognize the third party lens such as Tamron used with this adapter?
It recognized my Tamron lens!
Nice overview!
Thanks!
Thanks for checking out this video!
If you have one of these adapters, which one did you go for?? 🤔
Im sorry if this is something youve answered but I have to Ask😂
If I buy the Canon EOS R or RP(do you recomend one before the other for beginners?), and the sigma 24mm f1.4 art for canon, with this adapter will the focal length still be 24mm then?
I was going to buy the 6D mark ii, but seeing that it is an older model and heavier, maybe mirrorless is the way to go🤔
Correct, your 24mm will still be 24mm! As for which camera, they are both great. If looking at specs, the EOS R is going to just edge out the RP overall. More focus points, larger megapixel count, etc. If you do any video, the EOS R also is slightly better.
However, if you’re priorities are not so much spec related and more size and comfort, the EOS RP is lighter and smaller while still keeping up with the EOS R for the most part!
Hope that helps!
would you say that even someone new to canon EF or RF that it would be more bang for the buck to get used glass and buy the adapter?
I mean it all depends on what the camera being used is. If it's a DSLR, then I would recommend getting used EF lenses. If the new person is on a mirrorless, then I would tell them to see what they can get for used RF lenses, however I wouldn't tell someone who is new to drop a LOT of money. So I'd say get the base adapter and buy some used EF lenses to use with the adapter.
RF lenses are new, so they are the most expensive. Because of that, the price of EF lenses will slowly decline and there should be a lot more available as seasoned photographers start transitioning to RF lenses.
TL;DR
A new person to Canon EF or RF should buy used EF glass and get the adapter if necessary. Won't need an adapter if it's a DSLR.
is it worth it to buy ef lenses because they are cheaper now instead of the r mount ones?
100% yes, there’s nothing “wrong” with EF lenses. They just aren’t the new, shiny technology and understand they aren’t the lens of the future for Canon. But they are still quality lenses, especially the L-series EF Lenses, and it would be smart to take advantage of the lower prices due to newer technology.
I have Canon m50 mark ii and i bought 100-400mm rf lens. Is it possible or work out if i use Rf adapter???
No, it will not work. The M50 is an EF-M lens and won’t work with this adapter.
Can I adjust the exposure compensation with the control ring that comes with one of the models of the EF- RF adapter ?
Yes! You have to set it up to do so in the menu, but that is an option.
Hey man really appreciate your video, quick question. Would this work for a Canon EOS 6D Mark 2 with a Sigma 18-35 1.8f lens? With no distortion or vignetting?
The adapter in this video is for camera bodies with RF mount for lenses, so it can attach to RF cameras and EF lenses. The 6D II is an EF camera, so depending on the Sigma lens you shouldn’t need an adapter. However, just to cover all bases, the adapter only works one way. You cannot flip it around and use it on EF camera for RF lenses.
Hope this helps!
How can i do opposite mirror less lense to dsrl adopter
Unfortunately, this isn’t possible.
Will my Ef 50mm lens work with this adaptor for the canon r50
Yes
This might be a dumb question, but I just got a Canon R50 and I want to buy an adapter to be able to use EFS 18-135mm lens from my old camera meanwhile I save money for an RF lens. I know my new camera is better quality than my old one, so will using my EFS lens on my R50 essentially make my pictures the same as my old camera? Is it worth using my R50 or should I just stick to my old camera in the meantime? Thank you!
That’s a valid question to have! My personal opinion would be to use the new camera for sure! The EFS lens will not bring down the performance of the camera. If anything, the camera will help the lens shine a little brighter! Of course, the RF lens will have better quality in technical terms. But without looking too deep into anything you won’t see much difference between the two. It’s more how the equipment is used than how new/old it is! You’ll be fine using the new camera with the EFS lens 👍🏼
Happy shooting!
Since you did not tell what your old camera is it is quite hard to answer. The adapter is not a relevant component on image quality.
Is this adapter works with ef50mm stm prime lense especially autofocus?
Yes
I did not know I needed an adapter. Rushed home to try my new lens. Nope. Would not connect.
Oh shoot. Well I hope this helped clear up any questions you had! If not let me know
Lmao that was me trying to to put my lens on 😂😂😂😂
You’re not alone!
Thank you for this information
So then why did autofocus totally fail me when I used a Sony mirrorless with an adaptor to Canon EF lenses do you think????
So I actually ran into this too, I personally haven’t found an adapter that lets you use canon lenses on Sony cameras with full functionality. It’ll let you see the image, but I wasn’t able to change aperture or use autofocus.
I think I read somewhere that there ARE adapters that let you do this, they are just very expensive.
The main issue is canon lenses aren’t made to communicate with Sony cameras and most canon-Sony adapters don’t solve that.
@@CodyMajeresTHANK YOU!! Okay good I thought I was crazy haha, had a Sony for years and love my canon glass. Was never an issue as I was mainly doing video but now that I’m doing more photography not having autofocus has been such a bummer. Think I’m gonna get a Canon R5 I’m not meant for Sony lol
Canon does have some great glass! The R5/R5C is a beast of a camera. You will love it if you are already invested in canon glass!
I bought the cheapest camera with good reviews to see if I wanted to get into photography or not. My fear was spending a ton of money and losing interest. I purchased a Canon R50 on sale to give it a shot. I want some cool zoom lenses without paying thousands. I travel a lot and there's some photos I have taken with my phone that I wish I could blow up for home art, so I want to branch out to a real camera. I have the control ring adapter on the way and was going to purchase some used EF lenses on e-bay at a fraction of the cost. Is there any error in my way of thinking?
Not at all! You can get really great results with even the less expensive gear. Learning the proper way to use the gear will always outweigh better specs!
@@CodyMajeres Awesome, thanks for the confirmation! I was going to start with the 50mm "Nifty fifty". I also want a good zoom lens for nature or something capable of taking a picture of the moon. I have lots of research to do lol.
@@QuiresPan 50mm is such a great lens, you can’t go wrong there! As for nature, you could look for something like 70-200. Or like a 24-105. You could look for f/4 to keep the cost down.
can you only mount Canon ef,efs lenses to it? im new to camera world
It doesn't have to be a Canon lens, but it has to be a Canon EF or Canon EF-S mount. For example, my Tamron lens that is made for a Canon EF mount can be used with my EOS R by using this adapter. So any Canon EF/EF-S lens, or any third-party lens that is made for Canon EF or EF-S mount will be able to be used with the adapter.
Great video.
I thought I EF-S Lens wouldn't work?
I can confirm EF-S lens work!
@Cody Majeres Outstanding thanks
It works but if you have a FF body it goes into a crop mode. On some bodies you may disable it but you get huge vignetting. On for example RP you cannot disable it - also you cannot use any aspect ratio but 3:2
Soooo helpful!!! Thank you !
Does the adapter change image or video quality or focal length if used with EF or EF-S lenses for the RP camera?
No
Does the adapter shift a little bit I have a cheaper one the mount shifts with heavier lenses and stops works it show f 0.0
The mount does not shift, no. I’ve had the f/0.0 thing before (not with the adapter), and that usually means the lens isn’t connected or isn’t connected properly. I’m assuming that’s due to the mount shifting as you are experiencing. Probably not supposed to be happening!
@@CodyMajeres okay cool I have one I bought off of Amazon and it moves the slightest and that’s when the 0.0 happens it only started to happen when I got my 24-70. I shouldn’t have skimped on the connector and just bought the canon connector. It would stop all my recordings if it shifted and I didn’t realize it till halfway through the day of filming.
Ahh shoot 😕 yeah you should have a better time with the new one! If you don’t, let me know, we can troubleshoot 👍🏼
In the instructions for the adapter it says that it should be installed on the lens first, then on the camera. Any idea why and if it would be bad or produce some damage if I leave it on the camera and change EF lenses while installed?
Myself and many other people on the internet don’t understand why that is the written way. I always leave mine on the camera and treat it as if it’s just part of the camera. I’m sure they say to do it that way for legal reasons, covering their ass for any one-off mishaps, probably something along the lines of an attachment remaining on the camera causing damage after catching or snagging on something. Since it’s not technically a “part” of the camera, they will recommend to remove when not in use.
But like many others, I keep it on 😃
@@CodyMajeres Thanks!!
Great video. Subscribed
Hey I appreciate it! Look forward to seeing you around 😎
Thank you!!
"There is nothing in here that would introduce crop" I am confused by this sentence. Because increasing the distance between lens and sensor = crop
That would be crop factor and the distance is so minimal that it’s not noticeable. Unless you are pixel peeping maybe 🙂 not enough to claim a crop is introduced though.
I have 3 EF lenses one of which is L glass and none of them have that red dot or white square. Exactly where am I supposed to see them? Somewheres on the lens mount flange?
Are they Canon brand? I assume they are since you mentioned L glass, but if any are third party I’m not sure if they’ll have the same marking system.
As for Canon, yes the red dot or white square should be on the lens near the mount flange. It’ll still be on the black part of the camera, the side if you will. I’m trying to explain it best I can with words, but if you search Google images for “Canon Lens Red Dot” the second result is from Digital Photography Review and shows a great photo of both the dot and the square.
I hope this helps, sorry if I explained it poorly!
@@CodyMajeres The only red dot on my lens is the one that's an index mark and it's on the side of the lens and not on the flange which is what your video seemed to show (bit that it was all that clear to begin with - way out of focus/blurry and poorly lit). All my lenses are Canon.
The index mark is the red dot you’re looking for
On the lens it’s on the side. On the adapter it’s on the flange.
@@CodyMajeres To clarify - are you talking about the lens index red dot you match up to the red dot on the body for mounting? Your description isn't at all clear.
What about third party adapter like Viltrox?
I don't personally own that adapter, so I can't get as detailed. However, I know Viltrox is used by many as a third party adapter and seems to get the job done just fine. Sorry I can't be more help for your question, but I don't want to talk about a product I've never touched!
I have a t6i camera can I get a adapter to put on a ref lens
Short answer, no. The adapter in this video is for EF lenses and RF camera bodies, meaning the camera body has to have an RF mount. The T6i has an EF mount. To my knowledge they don’t make an adapter for an EF mount to accept RF lenses.
Can the adapter stay mounted to the body when changing lenses, or does it need to be detached and reattached to the new lens each time?
It can stay mounted! There's a small lock/unlock button on the adapter to unlock lenses and change lenses while keeping the adapter on the body.
@@CodyMajeres thanks! I was hoping there was a way to leave it attached to the body.
I got an r5c a few days ago, but the adapter won't connect my ef lenses to the body. It works every now and then, but then suddenly it won't detect the lens and I can't change the fstop or shoot anything. Do you have any idea why? I'm guessing the adapter I have is defect maybe. It also freezes the camera when this happens, but when I turn the camera off and remove the mount, leaving only the camera, it works normal again but without the lens.
This is weird! Sorry you’re dealing with that. Can I ask what lenses you’re using? For example, EF 85mm f/1.2.
I'm using the 18-35 EF from Sigma and the 50 mm 1.4 from Sigma. Both of those doens't work. I do have the 10-18 ef from canon which is also behaving weird when using the adapter on the r5c@@CodyMajeres
Hmm...ok. I don't think I have a solution/answer for you but I do have some thoughts and some suggestions! I hope this helps:
I'm thinking you maybe have a faulty adapter, as you also said in your comment. However, if you want to try a couple of things before sending it back, I would first check to make sure these lenses are compatible with the R5C. I'm not very familiar with that camera but I do know the R5 and the R5C have a list of lenses that just don't work with them. If you are confident the lenses are compatible, I would next ensure all firmwares are up to date. This includes lens firmwares and camera firmwares, they both have firmware. If the issue remains, I would double check your lenses and the adapter are properly attaching to the camera (listen for that satisfying "click" noise). If something isn't allowing either end to attach properly, don't force it. That could be the issue.
Even though I'm sure you've read this a thousand times, I would also note that Canon isn't the most receptive of 3rd Party lenses, however since you state this happens with a Canon lens as well it does seem to be more than just that.
I'll leave you with this: It sounds to me like it could just be a faulty device, and I hope that's the case! Based on what you described happens, it sounds like their might be a lack of communication between the lens and the camera that could be being caused by the adapter. But I will note that EF lenses are older and were made for different systems than what we have with these new R series cameras. It's also worth considering that your camera is just too much for these EF lenses and they are just not able to communicate with each other properly (which is why I suggest checking firmwares for sure).
I hope this helps at least a little bit and am hopeful that it's just a defect (and that you get a new one soon so you can use your new camera!)
I just purchased this adapter for EOS R... i am unable to mount my 400MM L 5.6F lens. i don't get it... you said that this should be compatible.
i nearly broke the mount, what's going on?
Are you able to describe the issues you’re running into? Based on my knowledge of that lens, it’s compatible with the mount.
What about the distance between sensor and glass ? Is this affecting anything ?
It does not
What wasn't explained in the video but the adapter makes up for the different distance between the lens mount flange and the sensor. This distance is less in a mirrorless camera than it is in a dslr. That's because you don't have the distance taken up by the mirror box. Hence why mirrorless cameras are smaller and lighter than dslr's.
how about using RF lenses on a EF /EFS camera body ? i could use one
This adapter only works for EF lenses on RF bodies.
are you aware of any EF body adapters that use RF? @@CodyMajeres
@@bakdogg I looked it up after your initial comment and I couldn’t find any unfortunately.
thanks for the effort 👍👍@@CodyMajeres
@@bakdogg Not possible. You can adapt only when the lens has a longer flange distance than the body. EF has 20 mm and EF 44 mm.
would you recommend i get a fish eye?
I would say that’s entirely up to you and what you shoot and what you want to get out of your next lens! I personally don’t have any use for a fisheye but you might!
Very helpful.
I have focus issues with my wide angle lenses on my EOS R and my R5C. When I’m at like 16mm it won’t focus on things far away.. any ideas?
How far away are we talking? Like infinity? I’ve noticed that happening with my R at 16mm a few times when trying to focus on clouds or things at infinity point. I think for my cases it had more to do with lack of light than anything. Not sure on your specific details if that could be the issue.
QUESTION: I have a generic ef adapter and used an ef 35-80 on my R8. I did a shoot and focus worked and shot a bunch of pics but now they won’t show up on my Mac or canon app. Anyone know what’s going on?
When the card is in your camera, do they show up in the preview mode on your camera? Can you review the images and see them there?
If you can see them on your camera, then I would next try to find a windows computer to see if they show up there. It might be an error reading your card on Mac.
I’ve never experienced this, so I’m just thinking out loud. Hoping someone is able to provide more insight!
@@CodyMajeres they showed up in the camera screen after I took the picture and when I hit play button to show the person I was shooting. Then I went back to shooting and finished.
When I got back home 1hr later all the ones I shot on the ef adapter are all blank black with a question mark ❔ they don’t show up on camera or in MacBook even though the rf lens pics show up automatically
I even tried a free data recovery website and it still wouldn’t show them.
Did you by any chance change lenses with the camera still powered on? From what I'm reading, that would have been a way to potentially corrupt the card.
@@CodyMajeres hey Cody. I think it was on actually. Where are you reading about that? Can you reply with a link? If that’s the case then that would be great to know that’s all it was. I have reformatted the card again so I can test and find out.
Absolutely, here's what I am referencing: www.dpreview.com/forums/thread/4538461.
Can I use for video shoot with all functions including eye autofocus
Yes, the adapter does not affect the ability to shoot video and does not remove any functions of auto focus. So yes, you can shoot video with eye-tracking auto-focus!
Will it introduce vignetting with a zoomlens? I own one with a vnd filter but it shows vignetting when going to 18mm with my sigma 18-35mm.
From what I've seen, the camera will introduce that vignette, but it's not due to the adapter. Reason I say this, I use the EOS R at work with OUT an adapter, and at 15mm I notice vignetting. I use the older 16-35mm ii WITH the adapter at home and I don't notice the vignette as much as the 15mm.
But mine doesn't take burst photos with an adapter on
I’d look into your camera model and if there’s been any issues. The adapter alone will not limit your ability to use burst, so it’s gotta be something else.
I increased focal length though correct?
Does not increase focal length
I just bought a Canon ef to eos M adapter and a Sigma 24-70mm f2.8 art lens and my camera won't turn on with it. Anyone knows why? It makes a rattling sound.
Is your camera the EOS R? If so, the EOS M adapter is not the right adapter and that could be the issue. You will need the EOS EF/RF adapter.
@@CodyMajeres It's an EOS M 6 II. you're probably right. Thank you. I'll look into it.
If you have the EOS M then I believe you have the right adapter. So that makes me think the adapter may be faulty? I don’t think a rattling sound is normal!! 😅 I’d maybe try to return the adapter and get a new one to replace it? That’d be my first action! Good luck!
@@CodyMajeres Thank you.
Do. you have a video on R5, R7, R10? Which one to buy?
I do not unfortunately, I haven’t used any of those cameras personally!
I just picked up an R7 yesterday and I can (sadly) tell you that no matter what brand of adaptor you buy, you most likely wont be able to use any 3rd party lenses. Just some food for thought.
Thats how I ended up on this video, I'm still looking for workarounds for my Tamron 17-50mm 2.8
@@DistractionPhoto If the third party lens is an Canon EF or EF-S mount, yes you can. I use Tamron lenses on my Canon EOS R with the adapter to this day!
Edit: Seems that the R7’s are having issues (and potentially others?). Sorry that’s happening, super annoying! Hopefully Canon can come out with a fix for this soon!
@@DistractionPhoto After looking this up, it seems to be an issue on Canon’s part with the R7. The adapter is designed to work with all models, however I’m seeing that the R7’s are having issues with the adapter.
Awesome info!
Appreciate you my guy!
I use an R10 APSC, and I have an EFS lens, can an EF to R adapter be used or do I have to use an EF to M?
EF to RF will work for the R10
@@CodyMajeres thank you,I think ef to r is only for fullframe, the R10 will be available next week, it's my second camera after the 700d, so I'm a bit new to adapters😁
The EF-RF adapter is to attach EF lens mounts to RF body mounts. The R10 has an RF mount so that is the adapter you want. It won't matter if the lens or camera is crop sensor or full-frame!
@CodyMajeres thank you for the explanation,i get confused because it new to me and the shop tell me to buy ef to m🙏but now i know and will buy ef to rf
Can you use it the opposite direction (i.e. EF/RF or RF/EF)?
No, one side is designed to be connected to an RF mount and the other side is designed to receive an EF mount. So if you flipped it, it would not work as then you would be putting a surface designed to receive a lens against another surface designed to receive a lens and vice versa. There would be no way for it to attach.
You cannot adapt mirrorless lenses to DSLRs as the adapter would have to have negative thickness. RF has flange distance 20 mm and EF 44 mm. An RF lens must be mounted 20 mm from the sensor and a DSLR has a mirror there. The only solution would be some adapter with optical elements and this would change the characteristics (the focal length) significantly or alternatively allow only macro shooting.
Is there an adapter for Canon 5d mark 2 for efs lenses?
I don't believe so
@@CodyMajeres Thanks for responding - there are some who say you can remove the plastic ring - but could damage the lens or mirror. Thanks for the great video.
Of course! I'm sure there are ways to make it work, but none that I would feel comfortable recommending to others as I have not done them myself.
One more note - you are an EXTREMELY talented RUclipsr - I am recommending you keep finding great ideas that excite you and please continue to post more content. You will get subscribers ... I just wanted to send a positive and encouraging note. Just subbed and gave a thumbs-up.
Thank you! I really appreciate that. July into August was real busy for me, but I'm hoping to have a few videos coming real soon with a lot of ideas for some others.
a year later, it’s now $130, not $99 😢
I was actually just seeing this yesterday 😐
Any noise ?
No noise!
The problem I have here is that I can’t find a single practical reason why going mirrorless is an “upgrade”. It’s a downgrade - and a way for the manufacturers to save money.
So my answer to this adapter dilemma was to keep my 5Dii and expensive EF glass - and otherwise kiss Canon goodbye.
That’s one way to solve it! What’d you switch to?
@@CodyMajeresI sucked it up and did what I should’ve done years ago. Went with the Leica M system.
These adapters cost more than some small engines.
is it me or is this video soft? To me its not sharp on his face...
