The adapter works great with my EF lenses when I attach it to the camera

Just loving this Canon R adapter. Allows me to use my prized Zeiss primes, Sigma Arts, and oldish EF lenses. So much utility in a small package. Canon Quality!

Perfect adapter. I use it on my R5 with my EF mount lenses.

I have many ef lenses and recently got a Canon R6 as my new main camera, so I needed this and it works with my ef lens with basically no difference in performance.

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.

Excellent adapter. Easy to install, easy to use. I will recommend

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.

Bought a Canon r5 and needed a EF lens mount adapter for my lenses. Just what I needed.

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

Works perfectly with all my EF Canon lenses…..I am so glad I purchased this product!!!

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

Easy to use. & great for beginner photographers! Great product!

It works. It's very convenient. Haven't shot with it yet but it works.

Bought this for older lenses for new R5 Mirrorless Camera.

So happy to have this extension for my camera. Now I get to use many different lenses!

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.

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.

I’m very satisfied that I purchased this adapter, works flawlessly

Works flawlessly. Makes our EOS more available for use with bigger telephoto lens that are not available without this adapter.

Works perfectly to adapt EF lenses to my RF camera.
