    Allows me to use my Ef lenses on my R6. Still have my EF mount cameras. Focus is just as good and picks are sharp as a tack. Also improved the focus speed on my 85 EF f1.2.

    A must have for use of your EF and EF-S lenses. Please note that where other manufacturers state their compatibility with EF-S, canon is the only one I have found to work.

    A complete no brainer for adapting EF lenses to RF mounts. The adapted lenses work flawlessly. I may get the one with the control ring too

    The adapter works to fit a EF lens to the EOS R body but it causes vignetting in the images.

    Being able to use all my RF glass on my new EOS R is great! Glad I only had to wait a few days for this! Makes the Transition to mirrorless a great experience.

    Two month R5 user and have been using strictly adapted lens with an aftermarket lens adapter that works FLAWLESSLY. Have been on the waiting list for this CANON brand adapter and the Control Ring Lens Mount Adapter which have been out of stock everywhere. This finally popped up being available and I jumped on it hoping for better focus, faster response and higher quality. Quality on par with aftermarket, Speed on par with aftermarket, price 2X's aftermarket with no gains except for Canon's name on the side. This one is going back.

    No, I would not recommend this to a friend
