Works perfectly with my EOS RP and new EOS R5. Each have their own unique controls. The control ring really adds situational control to capture perfect images.

Got a new Canon EOS R3 and needed adaptor for EF-L lenses. Works great with no lag, stutter or focus-hunting. Terrific adaptor.

Glad I spent the extra $

The mount works well with my Canon lenses and my Sigma lenses. I have the control ring programmed for the focus mode at the moment and it's nice to have the ability to easily change the functionality. Still working through the R5 options to see how I'll map the control ring function.

It works !

This thing does what I need it to do and with the added bonus of the control ring.

Works like a charm!

I have used it with all my Canon EF lenses on my Canon R6, and they all work just fine. The only exception with my R6 ,was the Tamron SP 85mm f1.8 which I truly suspect needs only a lens update and would be just fine as well. Thanks B&H for your usual great customer service!

It just works.

Works as advertised. All lens communications remain functional. The control ring adds a handy adjustment point - I use mine for EV adjustment.
