Customer Ratings & Reviews

Works exactly as expected. No setup or any configuration, just install it and it works. Lets you use your existing EF lenses just like you are used to.

Fits great, was worried about getting a 3rd party model from fears that they would be loose. Makes using my EF lenses a breeze, and I don't have to get rid of all my old lenses. No speed issues, in fact a couple of lenses actually seem to perform faster. Best buy purchase was easy, arrived in reasonable amount of time considering Covid shipping issues.

This adapter works great with my markii so I can still use my 50mm lens that I bought prior to my mirrorless camera. The images are still great quality!

I am using for my new EOS r6 mark ii. My older lens works perfect without any hassle. Autofocus works well too and fits well. No complaints!

Great adapter quality is excellent. No issues with performance!

Allows us to use our old lenses so we’re happy. The added length isn’t an issue. This allows us to consider other EF lenses like the zoom lenses that are cheaper than their RF counterparts.

I placed this adapter on my 500mm mkll and attached my r6 and the adaptation began. Great experience, works as described. I couldn’t ask for anything better to combine my new camera to an ef lens. Focus is fast and spot on. This adapter fit both camera and lens perfectly. Canon hit this one out of the park.

Upgraded to this from a T7 and seriously love it! Great quality and so easy to use. Great product for the dollar amount.

The Canon EF-EOS R adapter is an absolute lifesaver, especially for those looking to upgrade their camera body without the hefty cost of new lenses. It flawlessly connects my existing EF lenses to my EOS R series camera, preserving the image quality superbly. It's a smart investment that has saved me a significant amount of money. If you're planning to upgrade your Canon camera, this adapter is a must-include in your budget. It's reliable, efficient, and ensures a seamless transition to newer camera models. Highly recommended!

The adaptador woks amazing. It definitely worth it

i love this adapter!! my lenses fits so well using this adapter on my canon r6 which i also love! i totally recommend this purchase.

Works great with older lenses. Exactly what I needed.

With this adapter my EF lenses work flawlessly. The autofocus is just as fast as they are when mounted to my 80D. Great adapter! I will say, the one downside is not having the control ring. I have gotten quite used to the control ring on my RF lens and find myself missing it when I use my EF lenses.

Paired this with my R10 and it hasn't had a single issue with any of my EFS or EF lenses. Makes the jump to a mirrorless camera from a Rebel or D series way more painless. It does add about an inch of length to your lens when attached, so longer lenses start looking a little silly, and short pancake lens lose a little of what makes them compact. Also, EF lenses are much more available and affordable on the used market, so this becomes an amazing asset for quality and savings.

****Works great, not much to add. Just an adapter.****

Got for my R8. Works seamlessly to adapt my EF glass.

Canon's adapter is expensive compared to third-party options but built like a truck, so hard to complain.

Great adapter, bought a Canon R8 and don’t wanted to spend a lot of money on a new lens, got this adapter and I was able to use old generation lenses, works and connect perfectly to my camera

Great tool. Been very essential in my photography arsenal. Use this on all of my shoots since I have a RF camera using EF lenses.

I had trouble finding this in stock, but it's now available! I purchased this after using ef mount lenses and then recently purchasing the canon RP mirrorless camera. Adapter works great and saves a lot of money so I can use my EF lenses
