THANK YOU!!!! I was about to go and buy a Metabones to replace the Viltrox (which offers ZERO customer support) but followed your steps and fixed the autofocus issue!
Dear Graeme Simpson, I want to personally thank you about for this wonderful tutorial. It is now 1AM night time, and I thought I need to order new Viltrox adapter, but you saved! Now I can sleep well and ready to shoot tomorrow! :)) THANKS!
Worked! I was able to fix my 24-70mm and 24-105mm's wide angle focus! Turning my Viltrox's speed booster lens did the trick! Took a while but happy there was a solution.
If you're still not able to get infinity focus no matter how much you turn clockwise, this is what you have to do: Unscrew the Viltrox lens all the way until it comes out of the body. On the inside of the body, on the lip on the sensor-side, you will see a buildup of a glue-like substance. Scrape all of this off and then put the lens back into the body and rotate clockwise until you can't rotate it anymore. This is what worked for me.
I had the same problem with reaching infinity focus on 18 mm, thanks to your advice i've fixed that. Very nice to have wet towels for optics, i've used some from ZEISS in order to clean lens block and adapter inside after this procedure.
Darius Mackenzie I am having similar issues with my viltrox EF-M2, is there any images to go along with your procedure so I don’t turn the wrong screws and mess up the adapter? Thanks in advance.
I've tried this and I'm able to get it closer but nothing like shooting without the viltrox. Maybe the viltrox nf-m43x has more room because it has no contacts?
that rubber/glue scratch off advice did it for me!!! man - thank you. people need to add this to the video. I think the glue creates another layer that prevents the lens to fully go in.
YOU ARE A LIFESAVER! (Seriously, I was so happy I found this out, I called my mom about it as soon as I fixed it) BACKSTORY- I just dropped a lot of money on two lens. Both are EF lenses I use with and EF-R3 Speedbooster which allows you to use EF lenses on RF APS-C cameras. after owning both lenses long enough that I could not return, I found out they wouldn’t focus to infinity! I thought I was stuck with it forever bc I wasn’t going to be able to afford any new lenses, anytime soon. Then I thought what if it was the speed booster, but there was never any details about how to adjust focus on Viltrox speed boosters. (If there even is a way) So didn’t think it was a thing I could do. So I looked it up and your video showed me how! AMAZING, I can focus to infinity now!!! You have saved me so much time, effort and money! Thanks!
jeez, I had the EF-EOS M2 for my M50, and had the same problem, bugged me for a while, I thought I got an inferior adapter. Glad that I looked up this problem on youtube, Thanks! Now it is sharp!
Thanks a lot for that amazing tip, caz I was spending a lot of time and emotions trying to solve that problem ) I was thinking is only me person who has that issue One more time, huge Thanks from Moscow 🇷🇺 for great help
I just upgrade my old 50mm into stm version. I was so worry that I got I bad copy lens, it was failed to focus to infinity. Thank God I found your video.
I did as you said. No screw loosening but almost two clockwise turns. Perfect. My lenses all focus now. It took me 15 seconds. I would that all RUclips advice was as good and simple. I'm pretty impressed with the adapter.
I love RUclips. Tried to fix it somehow - even tested different lenses and couldn't focus correctly. You really helped me to fix this problem. Thank you!
Thank you, thank you, very much, it works!! In my case from Nikon lens to Panasonic GH5 VILTROX (NF-M43). But i had to rotate the lens from the back, because it didn´t work for me, no possible to rotate from the front side as you show on the video
Top man Graeme. New to the GH5, i got the viltrox to go with my 18-35 and was thinking WTF is going on here. But looks like i'm all set.. Cheers mate !
I was using a different brand, for an M42 to EOS-M adapter. From the look of yours, though, I'll bet it was the same (Chinese) mfr. If I'd known this, I'd have tried it before returning the adapter in disgust. I'm still having a problem with the non-lens adapter for the same camera & lens family. I think it's the circular ridge they put in there to push the stop-down pin on the lens. I'm waiting for a hex key from Germany (!) to be able to open the adapter & remove that thing. You'd think occasionally companies would test their products, instead of making us do it for them... and pay for the privilege!
IT HELPS ME SO MUCH for my sigma 18 - 35 with the infinity focus. THANKS !!! Now it is a lot better (at least it focus close object on infinity and almost as good at far distance on infinity. It was impossible before. I also get a bit more range of focus on 20mm+ on infinity. I will calibrate it also with the sigma calibrater for canon and I hope to get the sharpest possible image then...
does your sigma 18-35mm hold focus when zooming with the viltrox? Mine does not at the moment. I also can't turn it more since it gets very tight to turn. Might have to try to get rid of that residue inside as someone else suggested
thank you for your really helpful video! I just recieved my bmpcc4k and I really thought that I would need to upgrade to the metabones speedbooster bc I thought that the focus just would not work.. :)
I own a blackmagic pocket4k and this adaptor. I was googling for viltrox firmware upgrade, and recently had a great obsession with marvel movies. So basically this happened... Ef-m2 adaptor and infinity war= this video... 😂😂... Thnx a lot, it saved me a lot of money and resources... 🙂🙂
Thanks man. This worked for me, at least better then it was.. i kept my camera on and just took off the Sigma and then readjusted my Viltrox and then put it back on, and that for like 4 times untill it was acceptable. I now watch your clip and see that i should put my cam off when doing this. How can keeping my GH5 on while adjusting the Viltrox hurt my GH5?
Hello, how are you? I have a gh6 and I want to mount the sigma 18-35 but then there is someone who said that the electronics of the viltros m2 ii damaged the camera, it started flashing and it turns off when they connect it or connect any electronic lens to it. Turn off, it was a g85, what do you think happened and if I can mount that combo on my camera?
I'm having an autofocusing issue with my EF-M2 and Canon lenses where it will hunt in a small focal range and never find focus. This is the case with both the Canon 50mm f/1.8 and the Canon 85mm f/1.8. Using my Sigma 18-35 and Tokina 11-16, autofocus works wonderfully. Any idea what's going on?
I'm finding the auto focus to be a bit hit and miss with varied lighting conditions so have now gone to manual focus where possible. Unless I'm using the Feiyu Tech A2000 then I try to get away with using auto focus. Also, I'm not sure if all lenses are fully supported yet by the adapter.
I thought you had to loosen the little screw on the side of the camera mount before the element would rotate? Maybe not. I lost the little screw so I hope it didn't do anything important.

Dear Graeme Simpson,
I want to personally thank you about for this wonderful tutorial.
It is now 1AM night time, and I thought I need to order new Viltrox adapter, but you saved!
Now I can sleep well and ready to shoot tomorrow! :))
THANKS!
You're most welcome! I'm glad it helped
You saved me. I thought I was going mad. No one online reviewing the adapter mentioned this. Thanks!!
OMG, thank you so much!! This fixed the infinity focus for my new Canon EF 50mm f/1.8.
Holy cow, I was so stressed that I'd bought a bad lens! If I try this and it works, you've saved me a few hundred bucks :)
Worked! I was able to fix my 24-70mm and 24-105mm's wide angle focus! Turning my Viltrox's speed booster lens did the trick! Took a while but happy there was a solution.

Thank you. You're a gentleman and a scholar, and saved us from many troubles.
OMGI REALLY HAVE TO SHOUT THIS OUT: THANK YOU!!!!!!!! I have the exact problem with the same 24-105mm and now it works! THANK YOU AGAIN!
Best video i have seen in a very long time! THANK YOU
You're very welcome!
YOU ARE A LIFESAVER! (Seriously, I was so happy I found this out, I called my mom about it as soon as I fixed it)

Glad it helped you
Just used your tip to get the Viltrox working on my BMMCC G2 and it's fantastic!
Glad it helped
Glad I came across your video. I was worried I bought a broken item. Thanks so much!
Glad I could help!
Absolute godsend, I was sat here scratching my head thinking it was me. Much appreciated !
Glad it helped!
THIS stupid little problem was in my camera just over 3 years .... Oh god you have saved me
This simple video saved me from a terrible headache. Thanks!
So pleased it helped you
Quick and straight to the point! Thanks
genius simple!!!! please do someting on your audio level!! thanks for solution
jeez, I had the EF-EOS M2 for my M50, and had the same problem, bugged me for a while, I thought I got an inferior adapter. Glad that I looked up this problem on youtube, Thanks! Now it is sharp!
Your intro is like 20,000 decibels over your voice lmao
Yes have been told many times in the comments before. Nothing I can do about it now
I was looking for "Why the screws on the side headed to the lens are loose ?! Been this panned out to be a Gold Mine !!! Thanks ! 👌 👌 👌
Thanks a lot for that amazing tip, caz I was spending a lot of time and emotions trying to solve that problem ) I was thinking is only me person who has that issue One more time, huge Thanks from Moscow 🇷🇺 for great help
I just upgrade my old 50mm into stm version. I was so worry that I got I bad copy lens, it was failed to focus to infinity. Thank God I found your video.
Was having this issue with the GH6. Thank you
Thanks, no time wasted:) Only had to adjust my volume levels around the intro
Sorry about that. edited the video to remove intro
Awesome. This worked brilliantly. I found this doing one last search before plunking down the money on a Metabones. Thanks!
I couldn't get anything to focus correctly. Two turns later, it works like a charm. Thanks Graeme.
Bloody hell this works a treat! Thanks so much for sharing!
Was just about to buy a metabones for this issue. Absolutely genius, thank you!
Cheers man. Very helpful. All the best from Ireland.
no problem, glad it helped
I did as you said. No screw loosening but almost two clockwise turns. Perfect. My lenses all focus now. It took me 15 seconds. I would that all RUclips advice was as good and simple. I'm pretty impressed with the adapter.
awesome! glad the video was useful and now you have a great, fully working adapter.
Gearoid O'Laoi when did you know to stop?
I tested to see if AF in problem lens went to infinity. It did. It's trial and error. If you go a little past infinity it will do no harm.
I love RUclips. Tried to fix it somehow - even tested different lenses and couldn't focus correctly.
You really helped me to fix this problem. Thank you!
That's awesome! I'm glad I managed to help.
Thank you! Finally everything is on focus :D!
Nice - clear and concise. Like it!
That’s cool. I figured it was a limitation of speed boosters and didn’t think much of it.
I was wondering how my new Sigma lens was not working well. lifesaver. Thank you
Thank you, thank you, very much, it works!! In my case from Nikon lens to Panasonic GH5 VILTROX (NF-M43). But i had to rotate the lens from the back, because it didn´t work for me, no possible to rotate from the front side as you show on the video
YOU'RE A LIFE SAVER!!!!!!!! THANK YOU SO MUCH
You're welcome 👍
Thumbs up for saving my life, thanks sir!
OMG dude! I have been trying EVERYTHING to get this issue sorted on my GH5. Two turns of the element and done. Thanks so much! Liked and subscribed 😊
Awesome! worked perfectly on my Viltrox Nikon to MFT. Two turns. Thanks for the tip!
You just saved me $900, thank you! I do not need to buy another lens now...
Golden. Love you. PS: Same issue with the BMPCC4K (I found)
Thank you! I didnt expect this to be so simple
HMMMMMMMM did just youtube recommended this video to me before i gone mad?? :D thanks subbed
Top man Graeme. New to the GH5, i got the viltrox to go with my 18-35 and was thinking WTF is going on here. But looks like i'm all set.. Cheers mate !
Life. Saver. Thank you SO much dude!
No problem 👍
Thank you so much man! Upset I found out about this after doing some shooting but I'm glad there's a fix. You rock!
I'm not alone. I was so confused. Thank you!
Thank you for that great tip, Graeme: that fixed my problem on the Blackmagic Pocket 4K !
man you are a life saver.. thanks!
No problem!
Perfect fix! Thought it was my new lens at first but this fixed everything
Thank you ! Really easy fix and works fine! Your intro sound is quiet loud by the way! Cheers
Thank the flipping lord for you! Will test tonight and hopefully solve the problem!
You are a life saver. I thought I had a faulty lens!
Oh yes it helped me with my Tamron 24-70 2.8 G2 😍 I bought two of this and the problem was the adapter
Dave, du kleiner Schlingel...bist ja auch überall!
Many thanks for this. However, the glass element won't turn in either direction. Any clues?
Thanks. It worked!
I’m late to the party but DAMN my dude thank you!
thanks for the short answer!
You're welcome
Duuuude!!! Thanks m8, I was so desperate cause I can't afford a metabones at the moment. Thanks a lot!!
No problem dude
kek, I feel dumb because this makes a lot of sense and I should've thought of it. Anyway, awesome concise video!
Thank you, I almost threw mine away. LOL
Thanks for your great help. How could this not be mentioned in Viltrox official guidelines?😅
Glad it was helpful!

This is extremely useful. Very good tutorial and very helpful thank you.
Thank you man! Save my job!
Glad it helped you!
You're a life saver! Thank you! Finally I can use my Canon glass!! Multiple thumbs up if I could!

on auto focus it get to find the focus again... I am just trying it for videos, we will see
Thank you very much! This really helped me!
Loads of thanks, good job mate!
Wow thanks man!
STRAIGHT TO THE POINT!
funciona!! gracias!
HOLY FUCK I couldn't use my sigma 18 35 at 18 at first during two years before now ahah by such a small and quick fix, wtf
thanks dude, I was about to get pissed at the guy who sold me my 18-35
thank you for your really helpful video! I just recieved my bmpcc4k and I really thought that I would need to upgrade to the metabones speedbooster bc I thought that the focus just would not work.. :)
Thanks for that, really helpful! I guess my problem is mounting another 1mm adapter on top of the speed booster e.g. M42 to EF.
thank you sooooo muchhhhhh!!!!, you are a Genius!!!!
I own a blackmagic pocket4k and this adaptor. I was googling for viltrox firmware upgrade, and recently had a great obsession with marvel movies. So basically this happened... Ef-m2 adaptor and infinity war= this video... 😂😂... Thnx a lot, it saved me a lot of money and resources... 🙂🙂

It shouldn't but it was just good practice
Graeme Simpson Photography Thanks!
holy shit thank you!!!!! saved me
great tutorial!!! thankyou!
Thanks! Need to twist viltrox for each lens separately?
No it should be just the one time as that then puts the lens in the correct place for that camera
Thank you. this works!
Glad it helped!
Thank you so much!!!!!
Thank you so much for sharing this!!!!!!
Thanks for the video!
you are amazing.. I did it and noe I can ise my 10-18 efs in 10mm. before only in 11mm
That's great!

Thanks, Worked Perfect!
Thank you guy
It's called 'Back-focus adjustment', and it's something that all focal reducers may need doing to achieve best performance.
I'm having an autofocusing issue with my EF-M2 and Canon lenses where it will hunt in a small focal range and never find focus. This is the case with both the Canon 50mm f/1.8 and the Canon 85mm f/1.8. Using my Sigma 18-35 and Tokina 11-16, autofocus works wonderfully. Any idea what's going on?

is your tokina 11-16 working fine with this trick? without opening the tokina lens..
I thought you had to loosen the little screw on the side of the camera mount before the element would rotate? Maybe not. I lost the little screw so I hope it didn't do anything important.
thank you very much
Very useful!!! Thanks a lot
