Customer Ratings & Reviews

Got an EOS R for personal uses but since I also use canon professional, I grabbed this adapter to use my other lenses as well. It worked seamlessly and makes the value in having mirrorless and full frame even more!

Upgraded the wife to a R6 and didn’t know they changed the mounting layout for canon lenses with the new generation. This adapter allowed us to use her old expensive lens without losing any quality of photo.

Lens adapter works very nice with my EFS lens. I found zero fault with picture clarity.

Nice to be able to use my other lenses with the new camera

You probably need this as the RF lens selection is pretty sparse / expensive. Works flawlessly, have adapted a few different lenses from the nifty fifty to big lenses like the 70-200 f2.8, focusing is instant, IS works as well as on the EF mount

Is as advertised, only problem couldn’t figure out how to use with manual lenses

Great for be able to use other lens. Opens up more products to be able to use

I recently purchased the Canon EOS RP mirrorless camera body which included the Canon EF-EOS R Lens Mount Adapter. This allows me to use all of my Canon EF lenses with the RP body with no loss of functionality, or image quality. A really useful tool!

This product was very easy to install on the camera and use

Its works with my old EF lens, some of them working better than with my 80D. There is a crop on some of the EF lens when using with the R5, just beware, saves a lot of money not having to upgrade to all new glass

This product worked very well will the Canon R6 I purchased. It has been very easy to get on and off. I having seen any change in the operation. Seems to fit very well. I have used it with the canon 85mm.

great product works flawlessly, this helps the camera to attach ef lenses with ease

This item came in a bundle. I like when Best Buy do this.

Adapter is great. I returned it and bought the one with the ring that was on sale for $50 more.

All EF lenses work very well. My old 35 to 350 l lens works even better than on my other camera bodies.

this worked great to switch from a rebel T7i to the r100 and use the same lenses

I was afraid this was going to be bulky, but it's not bad at all! I barely remember it's there when I have it on my Canon R6. If you have ES lens with a mirrorless body, it's a must-have!

Works as advertised. Fits all my ef lenses. No need to get new ones.

Great adapter to adapting EF lenses to the new EOS RP camera. The EF lenses works as if there’s no adapter on.

Bought this to attach my sigma lens on my R6 and it works great. I went with this one as I never really use my control rings on my RF lens. Great product!
