EF-EOS R Lens Mount Adapter Auto-Focus Lens Converter Compatible with Canon EF/EF-S Series Lens and EOS R, RP, R3, R5, R6, R6II, R7, R8, R10, R50, R100 Cameras

It works great with my Canon EOS R100, it has a great fit! Very stable. Highly recommended. The price is worth it

Works perfectly with my R50 RF camera and Rebel EF lenses. Good seal, high quality, excellent photos.

Works very well in allowing me to connect my Canon R7 to a nice EF 70-300mm I got twenty years ago. I was falsely under the impression that all the Canon Lenses fit all cameras, but found different when I recently got my R7, and this adapter made the day by enabling me to put my IS Zoom lens on the camera and get great photos and videos, with no tripod needed at all for really great photos.

Works fine on my R8! I was worried about not getting brand name but it’s honestly been not a problem at all!

This is absolutely perfect! It’s very easy to use. Easy on and off every time I need to swap a lens. Very lightweight. I am so happy with this. Great quality for the money.

Great adapter for my camera. Lightweight, easy to use and seems to be built with good material. Would buy again

Decided to try out the world of Mirrorless Cameras (professional photographer for over 15 years) since I'm "Team Canon" due to their excellent customer service over the years I purchased a Canon RP mirrorless camera. Since I literally have thousands invested in EF lenses I decided to try this adapter ring since it's half the price of the Canon adapter. To my surprise it fit the RP body perfectly and all of my EF lenses fit on as they should and all of the Camera's functions work perfectly. Works well, great value, and quality is what you'd expect!

When I first bought the r100. I wasn't sure what to do with my old lenses, but when I saw this adapter I was happy to see that I could adapt my lens to the new camera. This adapter works fantastically, although the only complaint I would have is it tends to be a little tight on the camera ring and the same thing with lens.
