Customer Ratings & Reviews

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.

a great and work perfect love this perfet for canon lens ....its a good quality and nice

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!

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 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.

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.

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!

Great adapter quality is excellent. No issues with performance!

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

This works exactly as described! Fits all of my older lenses.

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.

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.

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.

The adaptador woks amazing. It definitely worth it

Great adapter, priced ok easy to snap in and use..

Works great with older lenses. Exactly what I needed.

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

this adapter makes using EF glass on RF sensor mounts easy to swap in the field. solid build quality, secure easy lock, and size makes it ideal to either leave on the camera or lens depending what glass you use most. good value, and since i don’t use/need the control ring on the $300 version, id say it’s a better deal. necessary for anyone moving from EF to RF sensors.

Combined with my R5 this works great for my EF lenses. This is the less expensive version that doesn't have the control ring. In hindsight, it might be worth the extra $100 for that functionality.

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