Hii Jason , I have sony a 7c . If I use either 11mm f1.8 apsc lens . Will it affect autofocus or anything that is going to bother while shooting video ... I need a wide angle lens in budget with low light conditions...
Another minus is Aperture. f2.8 becomes f4.2 and so on. Light is the same, bokeh is not. But after my trip and carrying Tamron 28-75mm f/2.8 on Crane M3 gimbal for 3 days, I regret not taking Sigma 18-50mm f/2.8 lens for my trip. Tamron was too heavy to carry all day.
That depends on how you look at it., A f/2.8 lens is always an f/2.8 lens, no matter the sensor size, and any f/2.8 aperture will give you the same depth of field. Depth of field/bokeh is not determined by the focal length or sensor size, it's determined by the aperture setting and distance from the subject. The reason it looks like you get less bokeh with a smaller sensor is because to get the same framing as you would with a larger sensor, you have to step further back.
APS-C f/2.8 lens is fully equivalent to f/4.3 FF lens in all respects. The weight is also typically scales as square of crop factor, all other things being equal, so equivalent lenses usually have the same sizes and weight. But often equivalent FF lenses don't exist because in general people buying FF cameras don't want such slow lenses.
@@joelmulder true but when you consider the crop factor let’s say you used a 24mm 2.8 cropped, the bokeh would be equivalent to the bokeh at 35mm when it’s at f/4.
@@JustinPinedaMedia In a practical sense, often yes. but only if you step backwards to get the same framing as you would've with fullframe. Sensor size and focal length are irrelevant to depth of field.
i have a A7R II and getting 18mp stills from my aps-c gear is pretty nice as a transition mode while I acquire more full frame lenses. but I still think I'll keep my a6300 kit since it's so small.
8:53 you literally described the fx30, better grip, good stabiulization, dual slot sd cards, and better lcd resolution, while also being cheaper than a full frame camera using a cheaper apsc lenses. ofc with a hit on low light performance.
you are so hilarious man, I just stumbled across your video on 4k shooters website when checking out whether I should buy aps-c lenses and I specifically came the youtube link just to tell you that you deliver your content amazingly :D
Wow. For someone new like me, just getting into a little bit more photography & video, you explained so much with clear and concise information. I thought investing in the APSC world would go to waste for the new A7III I just bought. Now I can say that I can just use it for video content for now, use my a6400 for photography and wait until I get my hands on a new lens for my new A7III. Subscribed ever since I looked into this field. Thanks a lot man! Looking to learn more from you.
i have the a7r4 and worked my self to 2 lens sony 24-105 (f4) and sony 100-400 when i need the reach i us apsc mode and now 2 becomes 4 and no extra weight and easy to carry.
Hi Jason, I am sorry I am still confused… if I use a 17-70mm APS-C lens on a full frame, will I get a wider angle ? Or will it be same as if I was shooting with a 25-105mm full frame lense ? Thank you 🙏
@@thebillygreen not sure if my comments are going through but I have the photo on my instagram. I had replied with a link shortly after you first commented.
Thank you, extremely helpful for someone like me that has recently "upgraded" from crop to full frame - especially the distinction between photography and videography for pros/cons. Question: what about the aperture? If I'm using an APS-C lens with let's say 1.8 constant aperture, am I still getting 1.8 on full frame? I'm mostly interested in the bokeh.
I'm a little confused on the videography benefits. I'm looking at the A7c paired with a Sony E 70-350mm APS-C lens. I appreciate for imaging I will lose resolution, but if i'm using it primarily for videography does that mean i'll get the additional aps-c reach with no loss in video quality?
I have an a7r3 with a bunch of full frame lenses that I normally use, but for trips when I want to go small and light I bought the Sigma 18-50mm f2.8 and the Sigma 56mm f1.4 which is still 18mpx.
@@pencilauyeung4863 I'm not sure what you're asking. In apsc crop mode at 18mm will be the equivalent field of view of 27mm on full frame. If I put the camera in full frame mode the image circle will be a little smaller than the sensor causing serious vignetting. Some zoom lenses have a big enough image circle at certain focal lengths to be used on full frame. For example, I had a Tokina 11-16 apsc lens for Nikon but when at 16mm the image circle was large enough to cover full frame.
I was thinking of doing the same. How does the 1.4 of the 56mm looks like compared to a 50 or 55mm at 2.1? Does it look similar creamy or is 2.1 FF still creamier? In theory, the DOF, should be multiplied by 1.5, just like the focal length. But I’m interested in real life opinions 🙂
Came here bc I'm extremely confused after the release of a6700 & A7cii. Want to know what's best for my budget. Thanks for these detailed but also easy-going style! After this, I think I'll go for the crop body, since size is a priority for me
Very timely video for me. I have an A6600 with Sigma 16mm. I keep going back and forth between staying with the A6600 and getting more APSC lenses, or just jumping to a full frame Sony body and building my lens collection from there. I'm a little paranoid about sinking too much money into the A6600 system and then deciding to go full frame later. Now I know what I can and cannot do with APSC lenses down the road if I do eventually move to full frame.
Okay, say for instance I’m using a SONY A7C with the Sony E PZ 18-200 lens. Will my light gathering be affected by the APSC lens on the full frame camera? I am a self filmed deer hunter so most of my important shots are going to be early morning and late evening when light is near darkness.
Watched this video and got info that took me three separate videos to get. Wish I came here first. I'm just starting my video career and bought a Sony ZV-E10. That being said, only bought it in a pinch and will be using it for about a year at best. Haven't bought much glass for it. Would you recommend buying th APS-C Lenses for the short term, or if I'm upgrading to say a Sony A7SIII in the next year or so, just start buying full frame?
I am still confused, if I take a picture with Sigma 16mm 1.4 on my A7iv and crop in to remove the vignettes in post how does it make the image quality any worse than taking it on my Tamron 28-75mm directly at 28mm ? In fact I think I would get a bigger field of view (22mm-24mm) on the Sigma depending upon how much I decide to crop off later in post. Can anyone comment or explain if this is right?
Great video, but now i need some advice from sony A7iii users. What is the image quality like when using an APSC lense. Does 10MP defeat the purpose of buying a full frame body ? Tamron 17-70mm f2.8 is a perfect around lense but will the image quality be a let down on my A7iii ? Im sure images would look better on a higher MP camera.
Hi Jason, I had a question stupid question probably i watned to get an A6400 and maybe upgrade to a full mirror after but how would I know if the lenses are compatible on both cameras? REalaly love your post thank you!
Rather than enabling the APS-C S35 Mode in the menu is there a metabones adapter or something similar you can put on the lens instead? I have an old APS-C lens I'm trying to use on my FX6.
Thanks, Jason for the great video. Will the Sigma 18-50mm F2.8 DC DN Contemporary APS-C lens work well on a Sony A7C Full Frame Camera for travel and astro photography? Many Thanks.
Why not use an APS-C body instead? You do not get any benefits for using a full frame body with an APS-C lens. Never ever buy APS-C lenses for full frame (unless you really know what you are doing and it is some weird cropped video mode)
Great review and many thanks for sharing; please correct me if I am wrong on the following; I have Nikon D780, purchased the Body only initially; coupled it with my Nikon 18-55mm , DX AFP VR lens; after experimenting with the in Camera adjustments, I found you can still use the Full Frame resolution (and get rid of the vignette) by simply zooming in to approx 24mm (which still gives you a wider image due to the full frame sensor); I have checked the resolution and its confirming its using all of the sensor!; if you use the DX crop function, it reduces the resolution considerably !; let me know your thoughts !! Cheers
I just purchased the A7IV a couple of weeks ago, I’ve kept my A6400, the Sony 16-55 F2.8 works AMAZING on both cameras definitely worth the investment on that lens for both cameras !
OMG! Took me a few minutes to process what the '70mm (35mm equivalent)' part actually means. I get it now Jason! Thanks for clarifying this confusion for me. Phew!
I love the Sony a7iv. But I’ll probably just get a few apsc lenses to start. Is it better just to buy the a6700. And in the future go full frame when I can get all the full frame lenses
Spend a little more for an R series. A7RIV will still give you 26mp of photos. I have used Sigma lenses at times and get great results. If you haven't made that jump yet, Wait for the specs on the A7V, it should be the price range of the A7iv when it first came out.
Investigating it seems that the x1.5 crop factor affects bokeh also, it means that if you are using an f1.8 aps-c lenses you will get and equivalent bokeh of a f2.7 full frame lenses. Tell me if I'm wrong.
If you use a full frame body, yes. On an APS-C body it does not matter what lens you use. Using an APS-C lens on a full frame body is not recommended. It is basically so that you will not completely lose your investment on the lens but it is always better to use FF lenses.
A7iii owner with G-Master glass. You totally rocked this video! Great review. This really makes me want to get some off-brand aps primes. Thank you. Dan
Thanks for the video.Just got the 11-20mm f2.8 For my Sony ZVE-10 and was wondering what would happen when I went full frame.Then I see you are also in Japan. I'm in Kyoto.
I put my apsc super wide on my new mirrorless camera just because it was the first lens I could grab to try some camera settings with a lens on it and was like woah.. there's no vignette.. this actually works? It's probably not really 10mm though right?
My brother, please tell me you mention using digital clear zoom to get more out of aps-c lenses on FF. I've seen people use the 10-18 at 10, and digital zoom to get a real FF 12mm rather than aps-c mode to get a 15mm.
Finally I've found your video. I've got a FF Sony A7 and I would like to use it like a compact camera... so what lenses? Your video is the answer to my question.
I love these experiments, in fact, I enjoyed using a tiny CCR lens on a bigger camera with the vignette and all I had to do was crop, except at times i kept it for certain compositions. But, to me, this is not the full solution, although it does the job. I will always be looking for an adapter with enlargement glass, that magnifies lens image to fit full sensor and even better, if there is a "zoom" ring to manually adjust. So far, no such adapter, so please, someone, make it, we will all love you forever.
This is what I want to do. I have an A7iv and I just returned the 24-105 as it was too heavy. I have Multiple Sclerosis and I struggle with my strength. I was told in various groups on Facebook the quality with the crop will not be as good as an a6600 and should just get a apsc if I'm doing that. What are your thoughts? I mainly shoot video and I may do a few photos for personal use, but only for Facebook, nothing too serious.
So let's say you are using an a1 with a 50mm FF, and a sony a6 series with a 50mm APSC lens to take the same shot with the same conditions. Let's also assume you intend to crop the FF shot in by 50% to match the APSC 's field of view. Would it be assumed that the Sony APSC shot would have more detail due to the 24MP sensor capturing that entire range, vs the '21MP' of equivalent resolution from the a71 one you crop in the FF shot to match the FOV of an APSC lens?
I have a bit similar confusion… will post processing affect the photos or videos without utilizing super 35 mode, like cropping out the unwanted blank spaces? Will you still be able to get the potential results of the lenses’ according to fstop? eg. getting an apsc lense 14mm f1.4 for FF camera use… does it mean I will always get 21mm f2.1 results?
You mentioned the frame equivalent (aka 10mm becomes 16mm) but you didn't mention the effect it has on the f-stop. Aren't I also losing stops by using an apsc lens on full frame?
No, an f/2.8 lens is always an f/2.8 lens, regardless of the focal length and sensor. But, to get the same framing on a cropped sensor/lens as you would on a fullframe sensor/kens, you need to stand further back. This increases depth of field. Also (and this is not applicable to cropping in on a fullframe sensor), if two sensors have the same resolution, yet one is smaller, the smaller sensor will always be worse in low-light conditions. That's because when the sensor is smaller, but has the same pixels, relatively fewer photons fall on each photosite. That's why amazing low light cameras such as the A7SIII only have 12 megapixels on a fullframe sensor. Because each photosite can be about 3 times larger than those on the 33mp A7IV.
@@joelmulder always? I mean if I go to mmcalc and put in my 10mm f4 on an apsc sensor, it's full frame equivalent is 15.3mm f/6.12. So if I'm using an apsc lens on an apsc body, I'm not getting f/4 but f/6.12. So if I use that same lens on a full frame body in apsc mode, I'm still getting a 15.3mm equivalent, but am I getting f/4 or f/6.12?
@@samozeal9466 Yes, ALWAYS. An APSC f/4 lens on a fullframe sensor will give you the same exposure as an fullframe F/4 lens. Because what do you think F-stop even measures? If f/2.8 meant something different on different lenses, it'd be a pretty useless measurement, wouldn't it? Smaller sensors are almost always less sensitive to light, that's just physics. Because with a smaller sensor, you have to reduce the size of the photosites to pack an equal number of them onto a smaller surface area. Smaller photosites capture less light. Those equivalents you're talking about are really only really useful when we're talking about putting lenses on sensors smaller than they were designed for, using adaptive optics. A fullframe lens covers more area than an APSC sensor's dimensions, but, if we use some glass to bend all the excess light back onto the sensor, more light is now hitting the same amount of area, and we've increased the lens' speed. You gain a about stop with Fullframe to APSC adaption, so a f/2.8 becomes a f/1.8. Yet because we've used an adapter, there is no longer a "crop factor" on the lens (don't get me started on why "crop factor" is entirely wrong terminology"). If, for whatever reason, you were to use optics to stretch an APSC lens' image field over a fullframe sensor, you'd loose about a stop of light. But we're not doing that when we're using APSC mode on the Sony cameras. We're just chopping off the vignetting while still using out very nice fullframe sensor. F-Stop isn't a perfect system for measuring light, some different lenses with the same f-stop will be a little faster or slower than eachother, but it's close enough that you won't notice unless you're in a very professional and controlled environment (T-Stop is much more precise, which is why we prefer it for professional video and cinema applications). So to conclude, when using a set ISO, shutterspeed, and sensor, any f/2.8 lens will give you the same exposure. Any questions?
@@joelmulder I guess I'll trust you because of the conference with which you speak, but I'm left confused by mmcalc. What is it calculating to determine a different f stop? You're saying that it's just erroneous?
@@samozeal9466 Well, don't trust me just because I sound like I know what I'm talking about 😂 I hope I can make you understand it rather than just convince you I'm right. No, it's not erroneous, it's just vague as to the implications. The converted f/ number you see has nothing to do with the amount of light coming through the lens. It's there to serve as an indicator as to what you can expect from your depth of field. I've never used mmCalc, so I looked it up. From their website: "...Although your lens is "f/2.80" it will have the equivalent depth of field to an "f/4.54" lens. The amount of light your lens lets in will not change, only the depth of field or the "blurry part" of the image." See, they themselves say that there is no bearing on the amount of light, only the perceived depth of field. The reason why an f/1.8 lens acts as a f/2.8 lens on a cropped sensor is exactly because the sensor is cropped in compared to full frame. This means that you have to walk further back to ge the same framing, and walking further back increases depth of field. A little clearer now? This is one of a couple common but closely related misconceptions many people have about the way sensors and optics work. It's related to how most people also think longer lenses create a shallower depth of field (more bokeh), while in actuality focal length has nothing to do with depth of field. Been thinking about making some youtube videos of my own about it to visually explain it. Seeing how many people have this misconception in this comments section, I think I'll actually do that.
You can use APS-C lenses even with the Sony A7S. The photos are only 5.1 Mpx, but they are still very good quality. I have the A7S and it's an excellent camera.
Hi Jason, may I ask a stupid question? For the Sigma 1850 2.8, can use in normal (FF mode)? Or there are shadows in corners that only able to be used under ASPC mode? Moreover, is lens compression 50mm or 75mm at tele end? (Is the 75mm view angle achieved by optic or simply cropping photo) I am thinking to buy a7c + sigma 1850 2.8, the compact form factor, has 18-50mm (up to 75mm in ASPC mode) can cover majority of use scenarios
My question is the exact opposite - let's say i buy a sony a6400 with the kit lens 16-50mm - the focal lenght is still 16-50 or is cropped even on a aps-c camera?
All lenses have their actual focal lenghts. That is why APS-C lenses are something like 16-50 mm when full frame are 24-70 mm or 24-105 mm. Smaller sensors need shorter focal lenghts.
@Wes Perry I'm pretty new to APS-C cameras since I use Sony full frame A7riv camera. I want to buy 11 mm 1.8 Sony lens. If I mount this lens on my camera, will the focal length stay the same, 11 mm?
The focal length cannot change. What 11 mm does changes depending on the body and the lens. Essentially you get the weakest link of the lens and body when it comes to crop. If you mean Sony E 11mm f/1.8, it is an APS-C lens so it gives 17 mm full frame equivalent view on any camera. On full frame you may get slightly more by cropping on post.

Another benefit of shooting video in APSC mode for the a7iv (and possibly a7iii) is faster sensor readout. Rolling shutter can be a bit much on those cameras in full frame 4k, but in APSC mode it's much more manageable. The a7iv in APSC mode has rolling shutter performance that's close to the a7siii. So even if you aren't shooting 60fps it can still be worth switching to APSC mode if you'll be doing a lot of panning and don't want slanty angles or jello-y footage

Hii Jason ,
I have sony a 7c . If I use either 11mm f1.8 apsc lens . Will it affect autofocus or anything that is going to bother while shooting video ... I need a wide angle lens in budget with low light conditions...
So if I buy a 35mm APSC for my full frame camera, it will be cropped 1.5 times and technically be 52.5mm? Is that right?
Yes that’s it
Another minus is Aperture. f2.8 becomes f4.2 and so on. Light is the same, bokeh is not. But after my trip and carrying Tamron 28-75mm f/2.8 on Crane M3 gimbal for 3 days, I regret not taking Sigma 18-50mm f/2.8 lens for my trip. Tamron was too heavy to carry all day.
That depends on how you look at it., A f/2.8 lens is always an f/2.8 lens, no matter the sensor size, and any f/2.8 aperture will give you the same depth of field.
Depth of field/bokeh is not determined by the focal length or sensor size, it's determined by the aperture setting and distance from the subject.
The reason it looks like you get less bokeh with a smaller sensor is because to get the same framing as you would with a larger sensor, you have to step further back.
APS-C f/2.8 lens is fully equivalent to f/4.3 FF lens in all respects. The weight is also typically scales as square of crop factor, all other things being equal, so equivalent lenses usually have the same sizes and weight. But often equivalent FF lenses don't exist because in general people buying FF cameras don't want such slow lenses.
@@joelmulder true but when you consider the crop factor let’s say you used a 24mm 2.8 cropped, the bokeh would be equivalent to the bokeh at 35mm when it’s at f/4.
@@JustinPinedaMedia In a practical sense, often yes. but only if you step backwards to get the same framing as you would've with fullframe.
Sensor size and focal length are irrelevant to depth of field.
Nothing becomes anything else.
Perfect video! Maybe one of little content creators pointing advantages from apsc lenses on full frame bodies. Loved it! Cheera from Brazil!
That is so good explaination. I have an a7r4 with only G Marter lenses, and I had never considered buying apsc lenses before. Thank you!
I recently bought a SONY 50mm 1.8 OSS lens and I use it with the A7S. You have to fiddle around a bit, but the photos are great.
i have a A7R II and getting 18mp stills from my aps-c gear is pretty nice as a transition mode while I acquire more full frame lenses. but I still think I'll keep my a6300 kit since it's so small.
That dumb n dumber “YEAAAAH” clip caught me off guard 😂😂
8:53 you literally described the fx30, better grip, good stabiulization, dual slot sd cards, and better lcd resolution, while also being cheaper than a full frame camera using a cheaper apsc lenses. ofc with a hit on low light performance.
Your videos always answer the questions I have about incredibly technical subjects. Thanks so much!
Hii!
I have a question.
I'm from Europe, from Hungary. KEH Camera have trasport in Europe?
you are so hilarious man, I just stumbled across your video on 4k shooters website when checking out whether I should buy aps-c lenses and I specifically came the youtube link just to tell you that you deliver your content amazingly :D
Wow. For someone new like me, just getting into a little bit more photography & video, you explained so much with clear and concise information. I thought investing in the APSC world would go to waste for the new A7III I just bought. Now I can say that I can just use it for video content for now, use my a6400 for photography and wait until I get my hands on a new lens for my new A7III. Subscribed ever since I looked into this field. Thanks a lot man! Looking to learn more from you.
i have the a7r4 and worked my self to 2 lens sony 24-105 (f4) and sony 100-400 when i need the reach i us apsc mode and now 2 becomes 4 and no extra weight and easy to carry.
Hi Jason, I am sorry I am still confused… if I use a 17-70mm APS-C lens on a full frame, will I get a wider angle ? Or will it be same as if I was shooting with a 25-105mm full frame lense ?
Thank you 🙏
In apsc mode (super 35), it will become 25-105, but resolution is greatly reduced
I am not sure if can work properly in normal mode
Used the crop Sigma 16 f/1.4 not too long ago to take one of my favorite photos this year.🔥
Can't believe that lil thing is still doing incredible work!!
Pic or it didn’t happen 👀
@@thebillygreen not sure if my comments are going through but I have the photo on my instagram. I had replied with a link shortly after you first commented.
@@fjhphoto my man!
Thank you, extremely helpful for someone like me that has recently "upgraded" from crop to full frame - especially the distinction between photography and videography for pros/cons. Question: what about the aperture? If I'm using an APS-C lens with let's say 1.8 constant aperture, am I still getting 1.8 on full frame? I'm mostly interested in the bokeh.
A7R4: 16-70 f4 for 26MP stills and for APS-C video. And that’s not to mention Clear Image Zoom in the mix.
dont forget if you use apsc mode in the a7siii you loose auto focus.......so its better to just crop in post to get rid of the vignette
Or you could use clear image zoom 😅👌🏼
Jason! I have the ZV-E1 and the 11mm 1.8 sony. Is the new 16-25mm 2.8 worth the upgrade?
I have A7S and 28-70 lens. You can turn on aps-c in camera and the photos and especially the video are still very good
I'm a little confused on the videography benefits. I'm looking at the A7c paired with a Sony E 70-350mm APS-C lens. I appreciate for imaging I will lose resolution, but if i'm using it primarily for videography does that mean i'll get the additional aps-c reach with no loss in video quality?
Love the content! Quick question, do you prefer cloud based storage or an external hard drive? Which company do you use? Thanks in advance!
Technically speaking. You should have both. On site and off site back up
I have an a7r3 with a bunch of full frame lenses that I normally use, but for trips when I want to go small and light I bought the Sigma 18-50mm f2.8 and the Sigma 56mm f1.4 which is still 18mpx.
May I check if can use normally in full frame mode? I .e. can you take 18mm photo?
@@pencilauyeung4863 I'm not sure what you're asking. In apsc crop mode at 18mm will be the equivalent field of view of 27mm on full frame. If I put the camera in full frame mode the image circle will be a little smaller than the sensor causing serious vignetting. Some zoom lenses have a big enough image circle at certain focal lengths to be used on full frame. For example, I had a Tokina 11-16 apsc lens for Nikon but when at 16mm the image circle was large enough to cover full frame.
@Dale Frolander thanks for the explanation
I am simple minded to think I can take 18mm photo
I was thinking of doing the same. How does the 1.4 of the 56mm looks like compared to a 50 or 55mm at 2.1? Does it look similar creamy or is 2.1 FF still creamier?
In theory, the DOF, should be multiplied by 1.5, just like the focal length. But I’m interested in real life opinions 🙂
Came here bc I'm extremely confused after the release of a6700 & A7cii. Want to know what's best for my budget. Thanks for these detailed but also easy-going style!
After this, I think I'll go for the crop body, since size is a priority for me
Me too confused between the two .. did u buy an a7cii? If then How is the performance ?
I don't know what to do , because if i want to use my Apsc lenses in my fx3 i cannot record in 4k, only in hd
Thanks Jason for yet another very informative and entertaining video! I always enjoy your content and presenation style.
Very timely video for me. I have an A6600 with Sigma 16mm. I keep going back and forth between staying with the A6600 and getting more APSC lenses, or just jumping to a full frame Sony body and building my lens collection from there. I'm a little paranoid about sinking too much money into the A6600 system and then deciding to go full frame later. Now I know what I can and cannot do with APSC lenses down the road if I do eventually move to full frame.
Glad this video helped clarify that! If you’re moving on to an a7R series or even the a7 IV, the Sigma should still be good enough to get you by!
Okay, say for instance I’m using a SONY A7C with the Sony E PZ 18-200 lens. Will my light gathering be affected by the APSC lens on the full frame camera? I am a self filmed deer hunter so most of my important shots are going to be early morning and late evening when light is near darkness.
Aps-c vs full frame in aps-c mode, does they have same low light abilities or still full frame is better in low light with crop mode?
Thanks!
Hey Jason, what are the hanging button tabs in the camera at 6:51? Are those quick release tabs to be used with a strap?
Watched this video and got info that took me three separate videos to get. Wish I came here first. I'm just starting my video career and bought a Sony ZV-E10. That being said, only bought it in a pinch and will be using it for about a year at best. Haven't bought much glass for it. Would you recommend buying th APS-C Lenses for the short term, or if I'm upgrading to say a Sony A7SIII in the next year or so, just start buying full frame?
I am still confused, if I take a picture with Sigma 16mm 1.4 on my A7iv and crop in to remove the vignettes in post how does it make the image quality any worse than taking it on my Tamron 28-75mm directly at 28mm ? In fact I think I would get a bigger field of view (22mm-24mm) on the Sigma depending upon how much I decide to crop off later in post. Can anyone comment or explain if this is right?
The best video about this subject! thank you man!
Great video, but now i need some advice from sony A7iii users. What is the image quality like when using an APSC lense.
Does 10MP defeat the purpose of buying a full frame body ?
Tamron 17-70mm f2.8 is a perfect around lense but will the image quality be a let down on my A7iii ?
Im sure images would look better on a higher MP camera.
Samyang has affordable ff lens for Sony, go for it
Hi Jason, I had a question stupid question probably i watned to get an A6400 and maybe upgrade to a full mirror after but how would I know if the lenses are compatible on both cameras? REalaly love your post thank you!
So there’s some debate on whether the f-Stop of the lens changes when pairing a crop lens on a Sony a7r(xx). Is there?
Hi great video keep going small question what about the quality of 1080p in crop mode on sony a7iii
Great video man, you packed a ton of useful info into it!
How come the 24MP FF sensor turns 10MP with the ASP-C lens? Shouldn't it be 24/1.5=16MP?
The FF sensor is 2.3 times larger!
No, it is 24 / 1.5². The crop affects in both directions.
Rather than enabling the APS-C S35 Mode in the menu is there a metabones adapter or something similar you can put on the lens instead? I have an old APS-C lens I'm trying to use on my FX6.
Thanks, Jason for the great video. Will the Sigma 18-50mm F2.8 DC DN Contemporary APS-C lens work well on a Sony A7C Full Frame Camera for travel and astro photography? Many Thanks.
Why not use an APS-C body instead? You do not get any benefits for using a full frame body with an APS-C lens. Never ever buy APS-C lenses for full frame (unless you really know what you are doing and it is some weird cropped video mode)
Great review and many thanks for sharing; please correct me if I am wrong on the following; I have Nikon D780, purchased the Body only initially; coupled it with my Nikon 18-55mm , DX AFP VR lens; after experimenting with the in Camera adjustments, I found you can still use the Full Frame resolution (and get rid of the vignette) by simply zooming in to approx 24mm (which still gives you a wider image due to the full frame sensor); I have checked the resolution and its confirming its using all of the sensor!; if you use the DX crop function, it reduces the resolution considerably !; let me know your thoughts !! Cheers
Very informative video as usually. Thank you!
i use some aps-c on my a7r2. especially for videos. at the same time i own a6400.
I just purchased the A7IV a couple of weeks ago, I’ve kept my A6400, the Sony 16-55 F2.8 works AMAZING on both cameras definitely worth the investment on that lens for both cameras !
Hey Jason, I really enjoy your video style! Very refreshing! ;) Thanks mate!
Jason have you ever shot the Tamron 18-300 on the Sony 7AC?
OMG! Took me a few minutes to process what the '70mm (35mm equivalent)' part actually means. I get it now Jason! Thanks for clarifying this confusion for me. Phew!
Thank you this was so helpful and on point!
I love the Sony a7iv. But I’ll probably just get a few apsc lenses to start. Is it better just to buy the a6700. And in the future go full frame when I can get all the full frame lenses
Spend a little more for an R series. A7RIV will still give you 26mp of photos. I have used Sigma lenses at times and get great results.
If you haven't made that jump yet, Wait for the specs on the A7V, it should be the price range of the A7iv when it first came out.
Thank Mr. Vong for sharing this great tip.
👍
Investigating it seems that the x1.5 crop factor affects bokeh also, it means that if you are using an f1.8 aps-c lenses you will get and equivalent bokeh of a f2.7 full frame lenses. Tell me if I'm wrong.
If you use a full frame body, yes. On an APS-C body it does not matter what lens you use. Using an APS-C lens on a full frame body is not recommended. It is basically so that you will not completely lose your investment on the lens but it is always better to use FF lenses.
A7iii owner with G-Master glass. You totally rocked this video! Great review. This really makes me want to get some off-brand aps primes. Thank you. Dan
I have a a6000. I'm not vlogger just a amateur photographer.
Any suggestions on an upgrade?
Last week I bought a used Sony 28mm f2 for US$250. It is very sharp on my A7iii and A6500, offering 2 focal lengths. Super bargain!
Legend. Exactly what I needed. 👊🏾
Thanks for the video.Just got the 11-20mm f2.8 For my Sony ZVE-10 and was wondering what would happen when I went full frame.Then I see you are also in Japan. I'm in Kyoto.
@jasonvong, I’m getting a Sony A7C, and I only have the trio of sigma apsc lenses, is the photo quality gonna be good??ish??
I put my apsc super wide on my new mirrorless camera just because it was the first lens I could grab to try some camera settings with a lens on it and was like woah.. there's no vignette.. this actually works? It's probably not really 10mm though right?
What about the OSS in APSC lens, does it still working in Full Frame Cameras
does this work with fuji lenses? are there adaptors for any brand?...are there any for MFT?
Damn, thats exacty what I was searching for. The perfect explanation !
My brother, please tell me you mention using digital clear zoom to get more out of aps-c lenses on FF. I've seen people use the 10-18 at 10, and digital zoom to get a real FF 12mm rather than aps-c mode to get a 15mm.
Always love the quality of your videos. You teje the time to make them entertaining and informative. Keep up the good work Jason!
Amazing. Exactly explain ALL my concerns. Great vedio, Love the style.
Finally I've found your video. I've got a FF Sony A7 and I would like to use it like a compact camera... so what lenses? Your video is the answer to my question.
With a a7r4, when using aps lenses. Would I still have to consider the 1.5 multiply?
I love these experiments, in fact, I enjoyed using a tiny CCR lens on a bigger camera with the vignette and all I had to do was crop, except at times i kept it for certain compositions.
But, to me, this is not the full solution, although it does the job.
I will always be looking for an adapter with enlargement glass, that magnifies lens image to fit full sensor and even better, if there is a "zoom" ring to manually adjust.
So far, no such adapter, so please, someone, make it, we will all love you forever.
This is what I want to do. I have an A7iv and I just returned the 24-105 as it was too heavy. I have Multiple Sclerosis and I struggle with my strength. I was told in various groups on Facebook the quality with the crop will not be as good as an a6600 and should just get a apsc if I'm doing that. What are your thoughts? I mainly shoot video and I may do a few photos for personal use, but only for Facebook, nothing too serious.
Is there any options to record in 8K using E-Mount yet.?
So let's say you are using an a1 with a 50mm FF, and a sony a6 series with a 50mm APSC lens to take the same shot with the same conditions. Let's also assume you intend to crop the FF shot in by 50% to match the APSC 's field of view. Would it be assumed that the Sony APSC shot would have more detail due to the 24MP sensor capturing that entire range, vs the '21MP' of equivalent resolution from the a71 one you crop in the FF shot to match the FOV of an APSC lens?
I have a bit similar confusion… will post processing affect the photos or videos without utilizing super 35 mode, like cropping out the unwanted blank spaces? Will you still be able to get the potential results of the lenses’ according to fstop? eg. getting an apsc lense 14mm f1.4 for FF camera use… does it mean I will always get 21mm f2.1 results?
Hello, nice video! I want to ask, will there be noise if i use sigma 18 50 on ff camera, or crop mode just cut frame and working normal as ff lens?
You mentioned the frame equivalent (aka 10mm becomes 16mm) but you didn't mention the effect it has on the f-stop.
Aren't I also losing stops by using an apsc lens on full frame?
No, an f/2.8 lens is always an f/2.8 lens, regardless of the focal length and sensor.
But, to get the same framing on a cropped sensor/lens as you would on a fullframe sensor/kens, you need to stand further back. This increases depth of field.
Also (and this is not applicable to cropping in on a fullframe sensor), if two sensors have the same resolution, yet one is smaller, the smaller sensor will always be worse in low-light conditions. That's because when the sensor is smaller, but has the same pixels, relatively fewer photons fall on each photosite.
That's why amazing low light cameras such as the A7SIII only have 12 megapixels on a fullframe sensor. Because each photosite can be about 3 times larger than those on the 33mp A7IV.
@@joelmulder always? I mean if I go to mmcalc and put in my 10mm f4 on an apsc sensor, it's full frame equivalent is 15.3mm f/6.12.
So if I'm using an apsc lens on an apsc body, I'm not getting f/4 but f/6.12.
So if I use that same lens on a full frame body in apsc mode, I'm still getting a 15.3mm equivalent, but am I getting f/4 or f/6.12?
@@samozeal9466 Yes, ALWAYS.
An APSC f/4 lens on a fullframe sensor will give you the same exposure as an fullframe F/4 lens.
Because what do you think F-stop even measures? If f/2.8 meant something different on different lenses, it'd be a pretty useless measurement, wouldn't it?
Smaller sensors are almost always less sensitive to light, that's just physics. Because with a smaller sensor, you have to reduce the size of the photosites to pack an equal number of them onto a smaller surface area. Smaller photosites capture less light.
Those equivalents you're talking about are really only really useful when we're talking about putting lenses on sensors smaller than they were designed for, using adaptive optics.
A fullframe lens covers more area than an APSC sensor's dimensions, but, if we use some glass to bend all the excess light back onto the sensor, more light is now hitting the same amount of area, and we've increased the lens' speed.
You gain a about stop with Fullframe to APSC adaption, so a f/2.8 becomes a f/1.8. Yet because we've used an adapter, there is no longer a "crop factor" on the lens (don't get me started on why "crop factor" is entirely wrong terminology").
If, for whatever reason, you were to use optics to stretch an APSC lens' image field over a fullframe sensor, you'd loose about a stop of light. But we're not doing that when we're using APSC mode on the Sony cameras. We're just chopping off the vignetting while still using out very nice fullframe sensor.
F-Stop isn't a perfect system for measuring light, some different lenses with the same f-stop will be a little faster or slower than eachother, but it's close enough that you won't notice unless you're in a very professional and controlled environment (T-Stop is much more precise, which is why we prefer it for professional video and cinema applications).
So to conclude, when using a set ISO, shutterspeed, and sensor, any f/2.8 lens will give you the same exposure.
Any questions?
@@joelmulder I guess I'll trust you because of the conference with which you speak, but I'm left confused by mmcalc. What is it calculating to determine a different f stop? You're saying that it's just erroneous?
@@samozeal9466 Well, don't trust me just because I sound like I know what I'm talking about 😂 I hope I can make you understand it rather than just convince you I'm right.
No, it's not erroneous, it's just vague as to the implications. The converted f/ number you see has nothing to do with the amount of light coming through the lens. It's there to serve as an indicator as to what you can expect from your depth of field.
I've never used mmCalc, so I looked it up. From their website: "...Although your lens is "f/2.80" it will have the equivalent depth of field to an "f/4.54" lens. The amount of light your lens lets in will not change, only the depth of field or the "blurry part" of the image."
See, they themselves say that there is no bearing on the amount of light, only the perceived depth of field.
The reason why an f/1.8 lens acts as a f/2.8 lens on a cropped sensor is exactly because the sensor is cropped in compared to full frame. This means that you have to walk further back to ge the same framing, and walking further back increases depth of field.
A little clearer now?
This is one of a couple common but closely related misconceptions many people have about the way sensors and optics work.
It's related to how most people also think longer lenses create a shallower depth of field (more bokeh), while in actuality focal length has nothing to do with depth of field. Been thinking about making some youtube videos of my own about it to visually explain it. Seeing how many people have this misconception in this comments section, I think I'll actually do that.
Very helpful. Got the Sigma 18-50 f2.8 for my old a6500 and am ready to upgrade to a a7iii or a7iv
Can I use an APS-C lens on the A7s mark 1?
You can use APS-C lenses even with the Sony A7S. The photos are only 5.1 Mpx, but they are still very good quality. I have the A7S and it's an excellent camera.
I recently bought a SONY 50mm 1.8 OSS lens and I use it with the A7S. You have to fiddle around a bit, but the photos are great
Great review jason! Im getting the sony 11mm for my a7siii. Mainly for real estate vids
Hi Jason, may I ask a stupid question?
For the Sigma 1850 2.8, can use in normal (FF mode)? Or there are shadows in corners that only able to be used under ASPC mode?
Moreover, is lens compression 50mm or 75mm at tele end? (Is the 75mm view angle achieved by optic or simply cropping photo)
I am thinking to buy a7c + sigma 1850 2.8, the compact form factor, has 18-50mm (up to 75mm in ASPC mode) can cover majority of use scenarios
Does shooting with an apsc lens affect low light performance?
My question is the exact opposite - let's say i buy a sony a6400 with the kit lens 16-50mm - the focal lenght is still 16-50 or is cropped even on a aps-c camera?
All lenses have their actual focal lenghts. That is why APS-C lenses are something like 16-50 mm when full frame are 24-70 mm or 24-105 mm. Smaller sensors need shorter focal lenghts.
This was really helpful, thank you!
Great video!
So, if I buy a 10-18mm APS-C for my A7S3 and use on APS-C mode, will I still get 10mm minimum or do I have to always multiply times 1.5?
you have to multiply, but the interesting part is that that lens somewhere in the middle also covers an ff sensor
@@cpr1087 Thanks. I have the 16mm 2.8 G but was trying to use the 10-18 APS-C at 10mm on the cheap-just for real estate (need the width).
@@CarringtonAdkins you're welcome
Superb information for video makers
this blew my mind. thanks champ
LOVE your videos and your energy!!!! =D
@Wes Perry I'm pretty new to APS-C cameras since I use Sony full frame A7riv camera. I want to buy 11 mm 1.8 Sony lens.
If I mount this lens on my camera, will the focal length stay the same, 11 mm?
The focal length cannot change. What 11 mm does changes depending on the body and the lens. Essentially you get the weakest link of the lens and body when it comes to crop.
If you mean Sony E 11mm f/1.8, it is an APS-C lens so it gives 17 mm full frame equivalent view on any camera. On full frame you may get slightly more by cropping on post.
what stabilizer are you using?
