Customer Ratings & Reviews

I’ll keep this short and simple. The adapter works perfectly. Buy it!

I recently bought a Canon RP to start getting into Full sensor cameras. However, coming from owning a 60d and an 80d a have quite the collection of EF-EOS mount lenses. Enter this adapter. On the RP does feel a little bulky with EF mount lenses and you have a cropping issues but to be honest I'd rather have that issue than a bunch of useless lenses. Love it!!!

This does what it's supposed to and with expected Canon quality. Using it on an R10 mirrorless with DSLR lenses.

This item makes it easier for me use my old lenses and save money.

Works as needed, even older lens work perfectly fine.

Works great connecting an L Series lens to the R5.

af still works great with adapted lenses. a generic one might work?

Great to use with your camera. It’s easy to attach and is very light.

fast shipping works great with all my lenses on my rp love it!

Works flawlessly when adapting ef mount lenses. Must have on a mirrorless system.

Great adapter so i can use my ef lens on my m50. I recommend

Canon has provided an easy way to seamlessly integrate your EF lens stable with the newer RF lenses. As a result, even if Canon hasn’t added an RF version of your favorite lens yet, you can still use the EF version with your R body. There are even different variations of this device available to add the control ring function found on RF lenses, or even drop-in filters.

The Canon EF-EOS R and EOS RP Lens Mount Adapter is a very useful accessory. It enables the use of EF lenses on the EOS R full-frame DSLR. There is a slight cropping effect when EF lenses are used in this way, but the EOS R's resolution of over 30 MP allows the image produced to be enlarged significantly. So this cropping effect is not limiting in any significant way.
