Thanks Henry. I know this is an old vid, but I appreciate you taking the time to talk about the mount's models and areas of confusion. I've been away from a/v for a while and while I have and older speed boosters, EF lenses and MF bodies, I had forgotten about what what and some of the specifics was. This was a good refresher. THX
I just bought a GH5 and this speedbooster, very keen to see how it performs. Will mostly be used for filmmaking with PRIME lenses, and a fast zoom lens here and there
thanks for the autofocus info. this is my 4th or 5th video searching for that info and you are the first to mention it. just a side note you can modify ef-s lens mounts to work by removing the part that sticks out. just do a search on it. on my particular lens I just popped the whole plastic piece on the rear of the lens out. some people grind it down. it might be different from lens to lens. always do your own research and verify that the modification you are attempting will work for your needs. if done wrong it will break your camera.
Thank you so much for your support on the video! That’s a great question! If I remember it correctly, here is the lens we were using: amzn.to/3ua9XgW The auto focus worked well for us with this combination. Hope it helps!
Confusing ?! I have EF lens that i use a M mount to connect them (Red dots) My purpose for buying this was to help my Telephoto lenses grab extra light ?! I have a Sigma 400 Prime Lens that goes completely useless with this (Bayonet). It hooks up directly to my Canon M50ii ?! Nice tut. !
I enjoyed the vibe, flow, and information in this video -- well done. Question -- does the platform that attaches to the EF-M2 II come with the device, or is it an extra?
Thank you so much for your kind words and support! It means a lot to us! That’s a great question! If you are talking about the tripod mount, yes, it does come with the EF-M2 II and it is removable. Hope it helps!
Thanks for the EF versus EF-S difference. Something I discovered the hard way is you cannot mount the Viltrox to a GH5 / GH5M2 with the Small Rig cage :-/ need to remove either the cage or the footer.
What type of adepter can I use for my LUMIX G80 aside the Viltrox EF mount. And also which adepter can I use on my G80 to use EF S mount lenses……. All Is That I need another optional adepter for my Lumix G80 so I can Use the EF S lenses
Thank you so much for sharing your experience with us! Yeah, that’s the only thing that no one really mentioned, but now we know. Thank you so much for your support!
I have a quick question about the Vitrox speed booster. I currently own a speed booster for my Canon M 50 and want to purchase an expensive L series ef lens. My question is, Will the Viltrox speed booster degrade the quality of this expensive canon lens I plan to use with it? Because no matter how good the Canon lens is, The image must still pass through the speed booster. thanks
Ever figure it out? I have questions, too! The manual says it's the "aperture adjustment," but I'm not finding additional information about it. What's it do, exactly? How do you use it? I'm using a manual lens, so maybe it's for electronic lenses?
hello sir I just bought a canon m50 and I'm planning to get this speed booster. But there is so many variation here in amazon japan. Should I get the Canon EF→M43 or the Canon EF / EF-S → Canon EOS M mount. Sorry I'm just a newbie. I hope you can help me. Btw I already sub. Thanks sir!
That’s a great question! You have to get the Canon EF/EFS to Canon EOS M mount adaptor because the M43 one will not fit your camera. Hope it helps! Good luck and have fun with your camera! Thank you so much for your support and subscription!
So if I put a Canon EF 17mm on a panasonic G9 with the speed booster it will become a 24mm, I thought it was the other way and it would become wider eg 17mm x 0.71 so it would become a 12mm?
Wait this is what it says on the website tho Viltrox EF-M2II Focal Reducer Speed Booster Adapter is designed to allow Canon EF and EF-S lenses to be used on Micro Four Thirds cameras.
You are very welcome! I have tried to put an EF-S lens on it but it didn’t fit because the plastic part was hitting the glass of the speed booster. Hope it helps! Thank you so much for your support!
That’s a great question! I heard that the M2ii has improved communication between the lens and the camera mainly on auto focus. If you only use manual focus lenses, I don’t think there is much difference when it comes to glass quality. Hope it helps and good luck! Thank you so much for your support!
When you leave the speedbooster on the camera and turn off the camera for a day, does it drain the battery? The Viltrox speedbooster for the canon m50 keeps draining the battery when not in use. I’m curious if it’s just a Canon M50 issue.
I’ve just noticed Viltorx Speedboster for my GH5 provide pretty large distortion when shooting in 6K anomorphic mode. Would this be just this my unit or is this a common issue? Much appreciated for informations.
Anyone used it with Irix stills lenses? Specifically the 15mm f/2.4. i know there's a compatibility chart but lots of lenses that are not listed, work fine with it. Like my Tamron 70-300. Not my Sigma 30mm unfortunately. My Tamron 17-50 2.8 gets a little too soft with the adapter but it's not very sharp to begin with, so just what I expected.
So sorry for this noob question but I just got the EF-M2 II to attach to my sigma 18-35. I simply cannot screw them together. It doesn't work. I don't know what's wrong. Please help, this is heartbreaking. I don't want to damage them by trying too hard.
Make sure you got the one for your camera and lens because Viltrox makes different adapters for different cameras and lenses. The adapter in the video is only for EF mount lenses to go on micro four third cameras. Hope it helps! Thank you so much for your support on the video!
A speed booster does NOT create more background blur. The speed booster only changes the EFFECTIVE aperture, meaning it gives a 1.8 lens the light of a 1.2 lens but the aperture blades aren't actually opening to a f1.2 so it will still give the bokeh of a F1.8.
Im thinking on getting it with my m6ii and the weebill s, you know if that little part under the adapter get in the way while trying to mount it on the gimbal?
I'm using a Tamron EF 16-300 F3.5-6.3 on my GH5s but keep getting a lense fault. Had the latest firmware 3.6 on the Viltrox but no luck :( Anyone with the same problem?
@@RileyBanksWho it's called a modification. It's something a lot of people resort to when they don't have the money to buy the gear they want. It must be great when you can afford to buy anything you want but, for those of us that can't, we have to learn to get by.
@@MrPhilbautista What about the warranty though? Say you buy this and "chop off" the extension part and then two weeks into using it, something is wrong with the speedbooster, now Viltrox won't even touch the thing. I think it's really important to understand that IF this gear is used for commercial shoots, you don't just 'buy' this gear, you use it for whatever production you need it for and make a return on that investment. I LOVE DIY film making, but I would not dare chop off parts even on my cheapest lenses🧐
@@RileyBanksWho LOL you're not chopping up the adapter. You're chopping up the lens. For sure Canon won't be guaranteeing that lens anymore but, considering they've phased out the whole line already, is that really that big an issue? Anyway, you do you. Mods aren't for the faint of heart.
@@MrPhilbautista I understand. Yeah according to what you're saying mods are not my thing, I just gather the gear I need 😅. The craziest 'mod' I have done is remove the rubbers from my Bmpcc6k as they are a pain in the butt when utilizing the slots.
That's a great question! I have never used the Metabones before, but I found the Viltrox sharp enough for my purposes. Hope it helps! Thank you so much for your support!
Thank you for disclosing this very useful info. Making EF-S lenses useless is a big deal.
You are very welcome! I’m happy that the video helped! Thank you so much for your support!
I just sat here for twenty minutes trying to see the difference between my EF and EF-S lens and couldn't see it. Glad I watched this video.
I agree with you! I couldn’t tell the difference until I tried it. I’m glad that the video helped! Thank you so much for your support!
Just what I was looking for. Just bought my first MFT camera and needed to understand all this. Thanks.
Thanks Henry. I know this is an old vid, but I appreciate you taking the time to talk about the mount's models and areas of confusion.

Thank you so much for your support on the video! That’s a great question! If I remember it correctly, here is the lens we were using:
amzn.to/3ua9XgW
The auto focus worked well for us with this combination. Hope it helps!
Efs lens can be converted to Ef lens as most have the extra end screwed on.
Thank you, I've been looking for a video like this for years. Excelent

Let say you can mod some of your ef-s lenses to fit ef mount by removing that extra plastic part..
Your video has saved me from making a bad buy. Most of my Canon lenses are EF-S or EF-M.
I have a quick question about the Vitrox speed booster. I currently own a speed booster for my Canon M 50 and want to purchase an expensive L series ef lens. My question is, Will the Viltrox speed booster degrade the quality of this expensive canon lens I plan to use with it? Because no matter how good the Canon lens is, The image must still pass through the speed booster. thanks
What does the tiny switch on the viltrox do? Not the big one to release the lens, but the one you can see at 5:44 by the viltrox-logo. Thanks!
Ever figure it out?
I have questions, too! The manual says it's the "aperture adjustment," but I'm not finding additional information about it. What's it do, exactly? How do you use it? I'm using a manual lens, so maybe it's for electronic lenses?
Awesome video. This was really helpful.
I'm looking to get this speed booster to adapt a Canon EF 70-200mm f2.8 L USM lens to a Lumix G7 (or G85)
did you buy this speed booster and did you still get the 2 x crop ?
Hello can I ask how you keep and maintain the speedbooster? Must you also keep it in a drybox?
Great info... illustrated with real world examples... Thanks
You are very welcome! I’m glad that you found the video helpful! Thank you so much for your kind words and support!
Sold!!!!!! Thanks Bro!!!!
You are very welcome! Thank you so much for your support on the video!

Thank you so much for your kind words and support on the video!
Well my only EF-S lens is the 60mm Macro ... and got also Tokina/Sigma Crop lenses .. but not "EF-S" .. thanks for the VERY important info!
thanks. did you upgrade to firmware 3.5? if so did you sea any improvment?

Legend was wondering about the ef and efs. Because its pretty confusing when never owning a lens. Thanks for this

Can I use EF-M (Sigma 16mm 1.4) on my micro 4/3 with this adaptor ?
That’s a great question! Unfortunately it will not work with EF-M lenses. Hope it helps! Thank you so much for your support on the video!
@@henrymediagroup ok, one more question, answer please
autofocus working with video mode? AF AF-c AF-S ?
Hey ! i only use manual lenses.. and i'm considering the first version of M2 . does the M2 ii has anything better in terms of the glass quality?
That’s a great question! I heard that the M2ii has improved communication between the lens and the camera mainly on auto focus. If you only use manual focus lenses, I don’t think there is much difference when it comes to glass quality. Hope it helps and good luck! Thank you so much for your support!
i got the m2 mark 2 and i think its better,
When you leave the speedbooster on the camera and turn off the camera for a day, does it drain the battery? The Viltrox speedbooster for the canon m50 keeps draining the battery when not in use. I’m curious if it’s just a Canon M50 issue.
My EFS Lens's work fine on my EFM2. I just pop the plastic bit out when I use them!
hallo!does it support stabilization of canon lenses?
I’ve just noticed Viltorx Speedboster for my GH5 provide pretty large distortion when shooting in 6K anomorphic mode. Would this be just this my unit or is this a common issue? Much appreciated for informations.
Can it be possible to Use Fotasy EOS M4/3 adepter on my Lumix G80 and be able to Ise The EF S lenses.
Do you know if afc runs with speedbooster?
1:35 : on Amazon it says "compatible Canon EF-S" it's more and more confusing.
Anyone used it with Irix stills lenses? Specifically the 15mm f/2.4. i know there's a compatibility chart but lots of lenses that are not listed, work fine with it. Like my Tamron 70-300. Not my Sigma 30mm unfortunately.
My Tamron 17-50 2.8 gets a little too soft with the adapter but it's not very sharp to begin with, so just what I expected.
Hi I I have canon M50 with sigma 18-250 can use this?
That’s a great question! As long as your Sigma lens has an EF not EF-S mount, it should fit. Hope it helps! Thank you so much for your support!
Do you get one stop of light on top of the equivalent of the aperture or on top of the actual (full frame equivalent)?
Will this NOT fit on the canon M50?
So sorry for this noob question but I just got the EF-M2 II to attach to my sigma 18-35. I simply cannot screw them together. It doesn't work. I don't know what's wrong. Please help, this is heartbreaking. I don't want to damage them by trying too hard.

You can actually use EF-S lenses with a speed booster, as long as you modify it by chopping off that extended part. Look it up in youtube.
Chopping off parts? Lol. Best to just purchase the right gear.

Guys u can still use efs Lens just cut the button part from the lens that thit
Its good info but I think this has been mentioned on almost every review and video as well.
I just made this comment to make it a 100 comments, it was 99❤😂

ef-s works no problem; use my 10-22 ef-s all the time. very simple mod. dude you are not helping.
hongkonger ?
Canon, it always sucks. This EF-S is not the same as EF is just ridiculous, and I have wasted a lot of money because of the difference.
