Customer Ratings & Reviews

Works great! wish it is a bit smaller. All of my Canon EF and Sigma Art lenses works well with the adapter.

Great for adapting my lenses to my R6 without upgrading all of them

Works well and does what it says it will do. No issues so far.

This adapter allows me to flawlessly use my old EF lenses on my new Canon R6 with no issues!

I had to test my camera with this mount but I didn’t see a difference if I could I would keep this instead of buying a rf lens

Its a great Product, But returned and got the Ring mount adaptor for the ring feature. Except Ring no difference.

This is a great tool if you don’t want to buy all new canon RF lenses

Looking for long time . It was available on best buy quickly then oyTher places.....no more 6 week wait

Very pleased with this! This works well with my EF lenses. No lags.

Works great for EF lenses. Seamless integration with my EF lens.

I've been using the EF adapter with my EOS-R since the R got released. It's been pretty awesome being able to use my EF lenses on the R.

It was great I bought it for my boyfriend and he loved it it was really nice packed and also it came very fast well recommend item

Must have accessory for the Canon eos R able to use my old canon ef lens

It’s free and you can use all your Ef and ef-s lenses with a super light easy to carry around full frame camera. What’s not to like.

Very useful gadget and although it adds extra length to your lens, it is not heavy, so you don't really notice the weight.

If you have bought the Canon R and have a Canon lens system you will need this in order to use your other lenses...

This is great if you have a mirrorless camera and still have some EF lenses. It helps save money on lenses. However, note that it doesn’t work the best with EF-S lenses. It’s not ask crisp.

If you have a bunch of EF glass from your DSLR this adapter is a must. Saved me $8000 while making the switch to mirrorless

This is a good addition to my new RP. I can use the EF lenses. Still takes good pictures

Solid adapter. It allows me to keep my current lens line up. I think the price is a little steep but it does what it's supposed to do. It came late via UPS but UPS did let me know in advance and provided tracking notifications.
