## Customer Reviews

### ⭐⭐⭐⭐⭐ This is the one.
*by B***N on March 31, 2025*

This is the one you are looking for. No issues. Does exactly what it says it does.

### ⭐⭐⭐⭐⭐ Great adapter for half the price!
*by T***Y on August 1, 2022*

I am not familiar with the autofocus performance of the Canon RF-EF adapter with the control ring, but this adapter is perfectly fast and has performed very well every time I have used it. The lens I use the adapter with is the Canon EF 70-200mm f/4 IS USM and it works perfectly. I am also a huge fan of the control ring. I would recommend this adapter to anyone who is on a budget and uses the control ring. It adapts well to my Canon EOS R and is half the price of the Canon control ring adapter.

### ⭐⭐⭐⭐ A nice alternative to the Canon brand
*by L***R on August 6, 2024*

This isn't the best-made adapter, but it works well and comes with the addition of a ring to enable different features on the camera (aperture, focus). And I haven't had any issues with it not communicating with my Canon EOS lenses and the the Canon R camera. Plus, the price is very attractive.
