Great adapter on my canon eos r!! Was gonna order an off brand but decided to go with the actual brand. :)

Perfectly fits for 50 mm 1.8 for canon r6 mark 2. Definitely good to buy.

Excellent adapter for my Canon R6. Flawless and seamless. Can’t ask for more! Thanks Best Buy!!

does not affect EF lens image quality even with L series Lenses

works perfectly. my sigma lens does not have any delay with my r5

All functions of my EF lenses work as they normally do. Feels super-solid. What more could you ask for?

this mount was a big part of why I went with the EOS R. Perfect for canon users who have old EF lenses. Works perfectly.

Definitely needed to use with old camera lenses , basic 99 dollar adapter was fine

This fits and works great on my Canon RP you don’t even notice it is there

Perfect product allows all my old Canon lenses to fit this new eye of Mount and yes autofocus does work

Works well with Canon EF lenses I have. Solid construction and lens are secured. No issues.

Works great with my Ef lens I can use less expensive lens instead of buying the newest products that High cost

Very well-built heavy duty gotta have it !! Fits perfectly

Canon did their customers a favor by creating this device so they can use their old glass with this R mount camera

This accessory is a must if you previously owned a Canon DSLR. The lenses work from my other camera are interchangeable!
