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

Works great! I switched from a Rebel XTi to a Canon RP and needed a mount adapter for my lenses. I’ve never had any problems.

Works perfectly with my R6MK2. Allows me to use EF lens

Fits perfectly, no problems

This is a decent converter for the camera. Sometime the focusing has a problem but overall it is good.

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.

I ask experienced users to confirm that this adapter works with my camera Canon EOS R 100P.S.I am happy to confirm that this adapter fits the lens perfectly. We can see how much more light flows through the new lens than through the lens that came with the camera.

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.

This converter worked perfect
