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

Does exactly what it said it would. The AF works great with the attached lenses. Fits snug with zero play and does not add much weight to the overall of the camera set up. Very pleased with the product.

Was nervous is wasn’t going to fit my camera but it did and works amazingly

Fit like a glove. Didn’t distort quality.

It works good, nice and tight

It's ok. Quality could be better. I have a shoot this Saturday and I need to use a long lens. I don't have the money to get an RF L lens. I lost my other adapter (found it this morning, drats). Compared to the Cannon adapter, it's not even in the same ball park concerning built quality. The only thing that the Snipiz has over the Canon is weather sealing. The Snipiz has it and Canon doesn't. The price of the Snipiz is about half the price of the Canon's though. It will get you through what ever you need to shot, it's just not as high of quality as the Canon's. I am going to put this adaptor on another one of my EF lens so it is useable.

The adapter is of excellent quality, especially considering how affordable it is!

This is a great adaptor. I have lenses from an 12-year old Canon EOS Ti-2 and I'm able to use them with my R100 now and still retain most of their functionality. The fit is tight and precise, and it comes with a small mounting foot on the bottom for a tripod mount. (By the way, remove the tripod mount before trying to remove the adaptor from your camera body.) The electronic relays built into it enable most of the lens functions seamlessly. All in all, very much worth buying: very happy with it!

Works well with my Canon 70-300mm lens on my R10.
