Customer Ratings & Reviews

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 add on I was afraid of purchasing the new camera because all the lens I already have. The lens adapter worked great. I can use all my old lens without any problem.

Super easy. Doesn’t take up a lot of space. I was surprised to find it also comes with its own little case to keep it in when you’re not using it too!

Easily attaches my old camera lenses to my new camera!

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

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.

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

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.

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.

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.

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

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

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!

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

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

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

It works good, it’s just a little frustrating I have to buy multiple pieces just to put my nice lens on my new camera. I wish the lens worked for all canon cameras. Now it’s just super bulky, the lens I have is a 24-70mm so it’s already a big lens, now this adds more weight.

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
