Customer Ratings & Reviews

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!

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.

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

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.

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 exactly what I needed lens fit perfect Just as product was described

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

Saved me so much money! I have Ef glass and I didn’t have the budget to get rf glass as well with my upgrade from a canon rebel t7 to a canon r50. So far no complaints!

Very very helpful, I use this to get use out of my older lenses on my r5c, incredibly useful for saving some money

I love this i use it on my camera thank you and i got it for Christmas

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.

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 use this to connect some older L glass to my R6 Mark II. Works flawlessly.

Great shopping experience with a lovely selection of items. The quality was excellent and everything was nicely priced. Very happy with my purchases!

This helps of you have older EF lenses. It will help with a more modern RF mirrorless camera

This purchase was really one of the best. It has helped my photography just a bit more.

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.

Works great! Was able to use my 50mm on my r6! Recommend!

It’s a very dimple device that works as described.
