This AF Mount Adapter with Variable ND from Commlite allows a Canon EF/EF-S-mount lens to be used on a Canon EOS RF-mount camera. Electronic communication between an attached camera and lens is supported, enabling autofocus as well as auto exposure features. If an attached lens is capable of generating Exif metadata, this adapter is designed to transfer that information, so that it can be saved with image files generated by the combined Canon lens and camera. The adapter also has a convenient variable neutral density filter.

Related Questions and Answers

Q: 1. Are the lenses not listed as compatible untested, or tested and failed?

A: The lenses and cameras not listed might just not have been tested. The manufacture does not list one way or the other.

Q: 2. Would this be compatible with Lumix S5?

A: Yes, this lens adapter is compatible with the S5.

Q: 3. Will this be compatible with AF and aperture adjustment on Leica TL series cameras, like the TL2, CL, and so on? The Sigma MC-21 adapter, for instance, is full-frame compatible only (SL, SL2, S1 + S1R, FP).

A: Yes this adapter is made to adapt Canon lenses to Leica tl/cl cameras

Q: 4. Can I use it between a Canon M50 and a 35 mm Sigma Art for canon?

A: Yes you can.

Q: 5. Will this work with a Canon m50?

A: Yes, it is compatible with the M50.

Q: 6. Does anybody know if this adapter work with Samyang XP lenses? Because Sigma MC-21 does not work properly with those lenses ( changing apature when taking picture - unusable for photo ) and it has the same problem with Video but it's kinda usuable ( when you hit record it changes apature by 1 EV and you have to manually go back. After stopping the record it happens again so its kinda anyoing for any kind of event filming)

A: It is our understanding that this adapter has not been tested specifically with the Samyang XP lenses. Your results may vary.

Q: 7. Does this support continuous autofocus while recording in video mode?

A: Yes. The following unit will allow all passive communication. Just be mindful that continuous autofocus is power hungry.

Q: 8. Will this adapter enable full frame use of the sigma 18-35? Sigma 21 adapter only allows crop sensor n lumix S5.

A: The reason you're only getting cropped sensor coverage is because that lens is only for cropped/ APS-C sensor cameras not for full frame, so the adapter you use isn't relevant.

Q: 9. When I use this adapter, I don't see aperture data on the viewfinder and am unable to take any photos. I've worked with it with three EF mount lenses on my R6, and the camera refuses to take any photos. Is it defective, or am I doing something wrong?

A: You need to enable “release shutter without lens” settings. This adapter does not transmit electronic data so it is normal not to see the information in the finder. You can change the aputure in camera or if using a camera with an aperture ring you can change using it on the lens.

Q: 10. Hi, I was looking for adapter for my canon m50 camera and I saw this adaptor is cheaper than original canon brand, what is difference between canon manufacture and your brand name, does it affect quality of the video or picture if I use non original canon adaptor ? Thanks,

A: This Viltrox EF-EOS M Lens Mount Adapter for Canon EF or EF-S-Mount Lens to Canon EF-M-Mount Camera would have the same functionality in mind as the original Canon version. There are no negative effects reported with the use of this adapter.
