Essential Adapter for EF Lenses on EOS R Cameras
Excellent adapter that works exactly as expected. It allows my Canon EF lenses to mount seamlessly on my EOS R camera with no noticeable loss in autofocus speed, image quality, or functionality.The build quality is solid, fits securely on both the camera and lens, and feels like a genuine part of the system. If you're moving from a Canon DSLR to the EOS R series and want to keep using your EF lenses, this adapter is a great investment.

Perfect.
Perfect, everything works on camera as it should. Reasonable price so I thought I'd get the canon rather than a 3rd party. Only buy it once so get the best.

Canon EF to RF adaptor for Canon mirrorless cameras
I've just bought a canon R7 to replace my old Canon 7d. The EF to RF adaptor is required to allow my old lenses to work on the new camera. The adaptor fits and works perfectly with no noticeable affect on picture quality. The adaptor arrived when amazon said it would and I wouldn't hesitate to buy again.

Great convertor
Good value, I can use all my L series EF lenses on the R5.

Canon adapter - well made, solid feel.
Bought the adapter after upgrading to a new Canon R7. Had EF-S and EF Canon lenses. All work perfectly well.The adapter feels well made and fits the camera and lenses well with a solid fit.Would recommend the Canon version to ensure full compatibility and communication between the camera and body electrics.

Works perfectly and feels very solid
It is expensive compared to some of the third party options but this one feels very very solid and has a decent weight to it making it feel stable and secure.Fits onto the body very well and doesn't affect any functions of the lens. The older EF and EF-S lenses still focus perfectly, in fact they're a bit quicker to find focus thanks to the better sensors on mirrorless than older DSLRs the EF lenses were made for.It also is weather sealed which secures an otherwise weak point in weather sealing between the body and older lenses.Comes with a decent protective sleeve to keep it protected in a camera bag.Ideally it'd be smaller, but that is a fact of how the bodies of these camera work vs the older DSLR so this isn't a fault of the product.

Flawless autofocus, worth paying for the official one
I recently upgraded to an EOS R6II camera but still have loads of old EF lenses. I read mixed reviews about cheap third-party adapters, so I bit the bullet and bought this official Canon one. It is absolutely flawless. The autofocus is just as fast and accurate as it was on my old DSLR, and there is no play or wobble in the mount. Definitely worth the money to keep your old glass working perfectly.

Get it!!!
I just bought a brand new eos r50 upgraded from a rebel t7. While I was excited, you can’t help but think about all the money you invested in the other camera. It wasn’t too long ago that I bought a very nice 75mm to 300 Ef lens. Well this fixes just that problem you’re able to use all your older lenses and buy ef ones at a cheaper price in general. You can get a converter for cheaper but I recommend just splurging and getting this one it was made by canon so ofc it’s gonna work the best. The auto focus works better than it did on my actual mirrored camera, it fits perfect, and I got it used like new and it came in perfect condition. Highly recommend to someone who just upgraded from a mirrored camera!!!
