Happy to have this ring soni can continue to use my trusty lenses i already had from my last camera.

Love my adapter! It's saved me so much money since I can use my old lenses despite my upgrade to a mirrorless camera

Love it!! Works well with my Canon R and EF 50mm 1.2.

works great with my EF mount glasses canon and tamron did not to have to buy RF new glasses witch are a little expensive may be in the future.

Just like most Canon product or adaptors they made. The adaptor is well made and good quality as you normally would expected from Canon. It is a basic adaptor for adapting EF or EF-S lenses to R mount.

I can use all my older lenses from my Canon 5D on my new R6! Love it! Totally recommend.

Like many other I got this free with my RP. As a hobby photographer I have been saving up for a new body. I already have my favorite ef lenses so this was all I needed to start shooting!

This is the perfect option to still be able to use my prized ef lenses on the canon rf system. Fair price too.

Bought this while I waited for the version with the control ring. Works seamlessly with my canon and sigma lens. Fit is perfect unlike the aftermarket brands.

excellent adapter for canon, essential if you have lenses with different mounts

Gets the job done! While I have not used many RF lenses, these works perfectly with EF lenses. I haven’t tried third party adapters but these has worked with every EF lens I’ve put on it seamlessly. My EF 50mm f/1.8 stays on it and I never have any issues. I’d easily recommend this adapter to avoid having to switch off the many EF lenses Canon users have already invested in.

Bought it to use my EF lens on my EOS RP camera. So far I do not see any problems with it. Only down side is that this makes lenses to stick out a little more.

One of my main reasons for getting the EOS R was this adapter. The EF lenses work with no problems. You have full control of aperture and the autofocus works like it would on a DSLR.

This works so well with all of my lens for my Canon R6Mark ii!

Autofocus remains super fast with this adapter and older EF lenses on the R body. It does add a bit of bulk to your setup but the smaller R body negates the effect, at least for me.

Works great with my old lenses and new camera. No need to replace lenses.

I believe this is a good transition accessory for your EOS R while you build up your RF glass, but I'm finding it sketchy at wide angles. No issues at 50mm and above, but when I shoot 16mm on my 16-35 it distorts a fair amount at the edges, and lens profile corrections in Lightroom don't help. If I had to guess there is just enough distance variation between the back of the lens and the sensor to tweak it a bit.

Works perfectly for my other EF lenses. A must have for high quality EF lenses.

It does everything you expect it to. Let’s face the facts. You will buy this adapter over a 3rd party one because it canon made. Stop reading reviews and just buy it

Works great for EF mount for canon lens and functions
