Customer Ratings & Reviews

Excellent product, works well for my older lenses.

If you are upgrading cameras and want to use your old lens this is a must. My one complaint which is not so much with the product but the compatibility is that it did not work well with my sigma art lens. It added some dark vignetting around the edges.

If you already have lenses from a collection you’ve built over the years; then this is a product you need. Why buy all new lenses because you’ve purchased an upgraded unit? Get this and save money by using your current ones. You can thank me now!!

Came well packaged. Works as expected. No issues so far in the past 2 weeks. Bought it for R6. Pricey but will do the job.

If you have a Canon "R" series mirrorless camera, and still want to use your EF lenses, you need this adaptor. Works great, supports the features of the lenses. You can just buy one and swap between your RF lenses or buy one for each RF lens.

Perfect adapter to my new EOS R and my EF lenses!!

I was a bit skeptical about the compatibility issues that I may face due to the adopter, but as of now even after 6 months of use, never encountered any flaws, except one or twice there was an random error message while using SD card from Sony camera i remember. Well worth, so i do not need to buy all set of new lenses.

This is for EF lenses to be mounted on R mount....

Easy to attach adapter that you forget is even there. The price seems a little high, but better than buying new lenses.

This works perfectly with the CanonR5 and using the old Canon lenses. I would recommend it.

The Len was a great choice for my camera . Great look

In order to use you ef and ef-s lenses with your new canon EOS R6 this is a must have item! Easy-to-use! First attach it to your lens then attach to your camera. Make sure your camera off when attaching the adapter and lens to your camera.

It as an amazing product, love it. Works great with old glass or older lenses.

Good thing this necessary addition to the photography equipment was available

If you're new to the Canon R/RP and already have a collection of EF/EF-S glass, this is a must have accessory. I got it in a kit with my RP and it works flawlessly (as expected) with my EF lenses. The focus is lightning fast and accurate even with my first generation 24-105 F4 L lens.

Great, friendly customer service and product works great!

It does not work for my camera. I have a mirrorless cannon so this does work for me but it does fit, I just can't use it nor return it :(

I went from a canon DSLR to a mirrorless camera. This adapter works seamlessly with my DSLR lenses. Very happy with this purchase.

It’s solid, that pretty much sums up my review. So far so good, as I haven’t run into any issues with the adapter ring with any of my canon lenses.

This free add on when I purchased my Canon EOS R to allow use with my EF lens. It works as described but ended up buying the adapter with control ring.
