The build quality on this is pretty nice but I get occasional errors stating stating the adapter connection is not good when it secure. I've missed a few good shots because of it.

It does what its supposed to do. Good fit. Adaps an EF lens to R series Canon body. All the functions like AF and f stop work in sync with the camera. Only issue which is not major is the fact that it adds a considerable length(~ 2") to the length. It would be good if a shorter version was available.

I bought this one for my second R6mk2, the first one I using with another EF/RF third-party adapter.Already tried it once and didn't find any issues. Later tried to connect Canon EF 16-35 and couldn't.I have some of the M42 lenses with m42/EF adapter from the same manufacturer - one of those adapters didn't mount to the Ykeasu adapter too

This thing works great. Recently purchased a R camera from Canon and needed an adapter for my older lenses. This works perfectly. Nice tight fit and all the lenses fit perfectly.

My camera stopped working while shooting using this product with my 300mm telephoto. Thought it was the camera but after I removed it everything worked fine. re-attached it and camera once again stopped shooting.

This adapter does what it advertised, conducting all the signals between the EF lens and RF camera. However, it does not fit snugly; there is some play (wiggle room) in the mount. Not sure if this will create a problem or not.

I have the Canon EF-R adapter, and I thought I'd try this EF-R adapter as it was significantly cheaper than Canon's. I'm glad I did. I find no difference in terms of AF speed or accuracy, or any other functionalities when compared to Canon's. Build quality seems just as good as Canon's as well. What I like about this adapter compared to other third-party ones I looked into is that it has baffles to reduce light reflection, just like Canon's.

Feels, looks and works as expected. Solid build. light. Absolutely no issues at the best price for this particular solution of Eos M to EF.

I have recently purchased the newly released canon Eos R10. After attaching this adapter which locks right in tightly no movement with my ef sigma art 18-55mm lens. All data reads perfectly with canon’s new focus system and something new to me where the camera shows the actual live focal range, confirming no issues!

I was initially hesitated to order this adapter due to its unfamiliar name brand. Its on sale, so I took the risk, thinking that if it did't work at least i could return it. To my surprise, it is very well made, fit and function perfectly on my Canon EOS m50 mark ii. I tested with two ef-s lenses, including the ef-s 24/f2.8 and 18-135/f3.5-5.6. The autofocus is fast and spot on. I have no issue with this adapter, Highly recommended.
