Customer Ratings & Reviews

Necessary equipment if you have an R camera and want to use with RF lenses. So much better than investing in new R lenses. I have used with both telephoto and macro lenses without any issues.

Allows you to use EF lenses on mirrorless R system. Your lenses will feel upgraded and easy to use. If you are financially ready to upgrade to RF lenses then this unit is a no brained.

I bought EOS R as want to try mirror less. But lenses are expensive. This is a life saver as I use my existing EF lenses with switches RF.

Great option for all your lenses. Too bad is not included free with the camera but, still a great option.

Fits perfectly and now I can use the EF lenses that have been collecting dust for years.

Just as described so you can use your older equipment

This is the Canon approved lens mount adapter for the Canon EF lenses to fit the mirrorless bodies. It's worked well, I've never had an issue, and if you're not willing to invest in all new RF lenses you'll need it.

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

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

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

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.

This is the least expensive adapter, but I think it does everything that is necessary. It allowed me to use all of my EF lenses on my R5 the way I used them on my previous D series cameras.

A must have as I was a EOS 5D MkIV user moving to EOS R and wanted to use all my beautiful EF L-series primes. Also allows you to buy 2nd hand EF lenses for much cheaper than buying the new RF equivalents. Build quality is pro-level, so a bit heavy.

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!

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.

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.

Fits all my EF-EFS lenses to my RF with ease while not being bulky either!

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

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!
