Great makes it easy for switching lens from my Rebel T7 to my EOS R6!

I have a number of EF lenses, so this is essential part of the kit if you buy a Canon R or RP body. I have had zero issues with using my EF lenses on the Canon RP that I bought.

Perfect to be able to allow me to use any camera lens with my canon without having to buy expensive ones.

I like this lens mount adapter it is small enough to carry in my camera bag.

Very good adaptor, corespondent very quickly and I have no problem at all with my different lenses ! Very sharp and smooth!

My combination is the R6 + canon zoom 100-400 and so it has worked great.

Almost seamless adapter for my R6 and L glass. Maybe a slight delay and softness of some images.

Works Flawlessly. Have been using it for 3 years and have no issues with it. It takes every EF lens I throw at it and even tried it with a Laowa Lense made for EF Line. NO issues with connection or functionality. Worth the price to continue to use an assortment of lenses. Here I have a pic of it using the EF 40 mm but I've also used the 50mm 70-200 L, &70-300 from Canon as well as generic zoom adapters. It's so easy to use too.

I was worried when I was purchasing the Canon R6 mk ii, that my l series lenses weren’t going to work well with the camera. Long behold, it works flawlessly. Thank you Canon to making this dapter! The only cons are some vingetting between the camera sensor and the lens itself from the dapter. It’s not too much of annoyance. I am worried that overtime, the seal between the camera body and the adapter will not stay sealed, also along with the lenses seal.

If you have invested in EF lenses, this adapter allows you to use them with a new R-series mirrorless camera. Easy to use and quick swap of lenses.

The Canon EF-EOS R adapter works great with my EOS RP when using EF and EF-S lenses, allowing me to use older glass without any compatibility issues. It performs exactly as intended, maintaining solid communication between lens and camera with no noticeable lag or connection problems. There is a crop effect when using EF-S lenses, which essentially gives a bit of extra zoom, but that’s not really an issue in practice—you just step back slightly to frame your shot properly. Overall, it does exactly what it’s supposed to do and makes expanding your lens options on the RF system extremely practical and reliable.

It fit perfect, look perfect and work perfect, with Canon, Sigma and Tamron lens for my new EOS R and all work right all the time. (1/2 month of use, 2 weedings and 6 couple photographic sessions) Cons: -The only one thing that I don't like too much is the release lever, it is tiny and sometimes difficult to use, but works well.

I tried other adapters different brands for canon and other lenses, all had issues interacting with my R8, but not this one. This one seems to perfectly adapt EF lens functionality for use on RF. I didn't notice any difference compared to my DLSR performance.

This was the best little add on for my camera, now I get to use all my fave L lenses from the ef mount on my new R6 mkiii. Works great, no regrets

This lens adapter has been a game changer! It makes using my Canon lenses completely seamless, with no hassle at all. The fit is perfect, and everything works smoothly—just like using native lenses. Best of all, it saved me a huge amount of money by not having to replace all my lenses. If you’re switching systems or want to keep using your Canon glass, this is an absolute must-have!

Great adapter for an RF camera, fast and slim adapter that unlocks a lot of compatibility within Canon lenses.

The Canon EF to RF Lens Mount adapter was a great purchase. It fits perfect on my Canon r10. I was disappointed because I have a Canon EF 85mm, I loved that lens, but I couldn't combine the lens and the camera until I did research to find out there is a way. Canon saved me, now it may just be my favorite combination. So grateful for the workers at Best Buy Fort Myers who helped me out in store. It may not have had a Black Friday deal when I went, but it's certainly not too expensive, and absolutely worth every penny. I have a few other EF lenses that fit and work in the camera. As for shutterspeed and aperture, I haven't noticed much or any difference.

I like that every one of my older EF lenses I have used on my new RF Mounted Camera is working perfectly. While I would like to have the money to get the newer lighter RF Lenses in the mean time I didn't give up any capability in my shots and was able to gain the ability of a newer and better Autofocus all thank to this adapter allowing me to swap my lenses and still have all the automatic features the lenses are capable of.

Works seamlessly! Easy to pop on and then use your lenses like normal. No learning curve or complications really. My only complaint is that the autofocus system on the Canon EOS R seems to have some trouble when using the EF lenses, but no issues with image quality or metering. I feel that is more to do with the camera body and software than with this adapter. This let's me use my more affordable but still wonderful low aperture EF lenses; even if they work better in manual focus mode I'll take it!
