Lens Mount Adapter EF-EOS R for Canon EF/EF-S Lens to Canon EOS R RP R5 R6 R7 R10 Cameras

great adapter! Does the job well, no differences compared to a directly mounted lens!

This converter worked perfect

Fits perfectly, no problems

This adapter does what it supposed to do. My EF lenses, large and small, fit perfectly using the adapter and all of the camera functions work flawlessly. Why did I give it 4-stars instead of 5? Here's why: Even though the adapter is not at fault, if Canon would get on board and significantly lower the prices of their RF lenses AND allow 3rd parties to make affordable lenses, then many of us would not need this adapter--for now, the better RF lenses are simply unaffordable for a great many Canon camera users. Peace.

The adapter is very nice quality and it does exactly what it’s supposed to do. My EFS lens snapped right in there and power from the adapter. Everything feels like metal and it has a nice texture too.

Fully functional, with no loss of speed or accuracy. I am not a fan of adapters, but it works PERIOD

I have a bunch of full frame EF Canon lenses. I have had no issue using this adapter with my Canon RP mirror less camera and Canon EF lenses. The only issue I have had is with an older Sigma 150-500mm as it appears the image stabilization doesn't activate when using this adapter.

The YKEASU ef to ef lens adapter is an absolute work horse for the price you pay, it fits perfectly on the RF body with only slight resistance towards the locked in position for lenses. It seamlessly identifies my EF 18-135mm lens and focuses and zooms in and out perfectly, while I haven’t tried it in any intense situations to test its weather sealed abilities I will update when I do try it out. There’s not play in the adapter which I know is a common complaint when it comes to other ef to RF adapters but this stays perfectly in place with no play. The only complaint i have which isn’t a major one is the lack of a thread adapter or some kind of mount to allow a tripod to thread into the bottom like other adapters do, but honestly it’s not a huge thing since I mainly shoot by hand but it would be nice to see them implement that into another version if they decide to do one. But I’m all honesty This adapter is a great alternative to the canon one and makes it an essential item in photographers tool kits.
