Canon Mount Adapter EF-EOS R

Canon Mount Adapter EF-EOS R SKU: 2971C002

Rated 5 out of 5 by from Works fine I was gifted an R7 to replace my 77D. I don't have the funds currently to buy new lenses so I bought the adapter so that I could use what I have. I haven't used it much, shot some wildlife photos while on vacation. It worked fine for that.

Rated 5 out of 5 by from Rf-Ef adapter Easy to use. Works as it should. Allows me to use my EF glass on my R50

Rated 5 out of 5 by from Keep your current lens collection, upgrade to mirrorless Once you align the correct dots, it fits snug and secure.

Rated 5 out of 5 by from Excellent adapter for older EF/EF-S glass I had hoped to be able to get all new RF lenses but was unable to before a trip and so I ordered the basic adapter and used it with a Sigma 18-300mm EF-S lens on the trip with excellent results. The adapter and EOS RP body gave excellent sharpness and colors. Sharpness was better that I have ever achieved on a T2i and 77D. Now I may look to get some good EF lenses to use with the adapter but I love the 2 RF lenses I have purchased so I get the best of both worlds.

Rated 5 out of 5 by from Good deal Works well with all my EF lenses. The overall camera length is then about the same as if they mounted on my old SLRs.

Rated 4 out of 5 by from EF to R lens adapter Works flawlessly. Excellent fit/finish - like a part of the camera, not an attachment. Only thing missing is tripod mount (like the EF-M adapter would be great).
