Customer Ratings & Reviews

This adaptor works great with my EF lenses. Quality product, would not go with any other brand.

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.

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.

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.

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.

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

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.

Works as advertised and allows you to use your old 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.

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

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

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

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!
