If you have any canon DSLR lenses your going to need this to use them.

Works flawlessly adapting ef glass to the eos r body!

Is good adapter for you camera I have recommended for everybody

Hope to add more lens soon....Learning is a slow process.

For the price and build this is essential to the EOSR.

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.

Great item will sure pass by to get more from Best Buy

I bought this to adapt lenses to an R5 MK2. I'm not impressed. I have 3 lenses I mostly use. An EF 16-35 II F2.8. That one is ok but I replaced it with the compatible 15-35 because of the IS. I have a 100-400 that performs poorly with this adapter. The lens IS doesn't work at all and I can't tell if the in camera one does. Third I have a 24-70 F2.8. This lens has not been used a lot and doesn't work at all with the adapter on the R5 MK2. I get an error o1 lens and camera not communicating clean contacts. The clean contacts message is ridiculous to begin with. Canon service described why and suggested service. Of course. This lens works perfectly with the 5D MK4 I purchased it for. I'd think about getting the more expensive adapter but so far I can't find anything telling me what is different about them.

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

Allows me to use my old lenses with my new camera! Love it!

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

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

Love it I get to use my sigma!!!!!!!!!!!!!!!!!!!!!!

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

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.

Good thing this necessary addition to the photography equipment was available

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.
