Package 1 x EF-EOS R1 Lens Mount Adapter 1 x User Manual (English & Chinese) 1 x Front Cap / Rear Cap Review: Works great! Now I don’t have to rebuy my lenses! - This works great! All control connections pass thru to my Canon lens just fine. I tested this with my canon R100 R-mount camera body using my EF-S 24mm Canon prime lens. Auto focus worked, image quality was good and left it on servo focus so it would have to constantly communicate. No problems. I attached evidence of a pic that I took of my dishwasher with the new setup. Be aware the mount is tight to the camera body, so for the lady that did a video saying it didn’t fit, you have to use both hands and firmly hold it while turning. It locks nice and tight. Nice bonus they included a way to remove the bottom tripod mount if you need to but I assume that’s another reason for the tight fit.
