Customer Ratings & Reviews

I was worried that I would not be able to use my other camera lenses with my new camera. Now I can! This adapter is easy to use.

Allows me to attach my sigma EF mount 35 1.4. You need to turn off lens correction from the menu on the canon R7 but the lense auto focuses and works perfectly.

Just what I was looking for. Recently purchased a R7 and wanted to be able to continue using T7 lens.

Awesome and keeps my EF lenses relevant. Keeps me in business, while making quality photos until i can afford better quality RF lenses.

If you are migrating from a previous Canon series that uses EF lenses, this adapter is a must...but it also makes the transition seamless and worth it! I was able to make use of all my EF glass without missing a beat. No compromise to image quality at all.

Perfect pair while you build up your RF glass and need to use your EF lenses. No issues with third party lenses like the Tamron 24-70 2.8 G2. A must have if you're hoppping into the mirrorless line up with a bunch of EF lenses.

Great product works amazing with my R6 markII and issues on the photos while using the ef lenses

This was a hard to find item and BB had it instock. Perfect seamless fit with all my EF lenses on to my Canon Mirrorless cameras (EOS R) .It is made by Canon and sold by Best buy . Always great combination

That is the good one to extend any lens of canon to the mirror less one . It works well , everything smooth

Seamless adapter that works extremely well. I use this for my Canon 300mm 2.8 on my R5 and it works flawlessly. The autofocus works well and I have no issues with it!

Works as advertised and allows you to use your old lenses!

EF to EOS R adapter works very good with canon EF lenses. This model does not have the control ring which is awkward to use and easily hit to make unwanted adjustments. This model in my opinion is the best adapter to purchase

it fits my old lens for my new camera. this product save me tons of money because I dont have to buy new lens for my mirrorless camera

Good for people who switch from crop sensor to full frame and don’t want to buy all new lenses

I love this piece! I'm able to use my lenses that I already have until I'm able to get some new lenses!

Was exactly what i was looking for to be able to use old EF lenses on the new R6 mark II with the new RF style lense adapter

Great overall. Looks like it came from factory and no side effects to pictures

Great adaptor, did what i needed it to. I had a bunch of old lenses and so this helped alot.

This has been the most requested item in 2021 as you can use it with all EF lenses using the Canon mirrorless cameras. I finally got one and am pleased with how my 200MM F2 handles with this adapter attached.

Pleasantly surprised Best Buy had this product in stock (at the time of order) when Canon was back ordered. Works great. Used it over Christmas with my Canon RP and a 70-200mm 2.8 and 50mm 1.4. Both lenses worked well.
