Customer Ratings & Reviews

The product is really good. I would like to thank Best Buy for their helpful guidance and great customer service

A must have if you're coming from an EF-mount camera and don't want to have a bunch of useless lenses. WARNING: Not all EF lenses work 100% with some of the Mirrorless cameras. They will function fine, but some wider lenses will have the inner barrel black in view. Not an issue with the adaptor itself, just a function of adaptation and different sensor sizes.

This works great with all of my EF lenses to my R6 MarkII. Using this adapter makes more sense than having to buy a different set of lenses for the new camera. I have not seen any issues so far!

Awesome adapter. Ef lenses work better on RF bodies than they did on the DSLRs. This is definitely worth it over 3rd party ones.

Ef to rf adapter works great for using ef efs canon lenses or any lense with an ef or efs mount like sigma or tamron on canon r series mirrorless cameras ( r3 r5 r6 r7 r8). The build quality is great and it comes with its own case, saved me lots on buying new rf lenses.

I’ve been using this adapter to mount my EF lenses on my EOS R camera, and it works really well. Autofocus is fast and accurate, and image quality doesn’t seem to be affected at all. The build feels solid and secure, so I don’t worry about my lenses.

This works perfect i can use my ef lens on my rf camera

amazing product if you don't have newer R lenses this helps a ton!

Works great with my R6 Mk2 and Sigma lens. Does not add too much weight.

I switched to Canon mirrorless camera's last year, and thanks to this little adapter I can continue to use all my old EF series lenses on the EOS R5. This way, I can slowly replace my gear without breaking the bank. Can't go wrong, these are just an electrical passthrough so no optics to mess with picture quality. I've used with multiple lenses, none had any performance problems because of this adapter.

great communication and easy purchase. product works great

This allows me to still be able to utilize my EF mount lenses for my RF mount camera body. It’s easy to install and break down when not in use and comes with a handy case to store it in.

Absolutely must for our Canon r6, unless you plan on buying all new lenses for your camera or are just starting out with no lenses. We have a ton of lenses that we have been using on our Canon 5D Mark iii and when the sensor stopped working we had to purchase a new one and decided on the Canon r6. This adapter made that decision easy for us since it allows us to use all our current lenses on it. By the way, we LOVE our Canon r6!

The adapter has worked perfectly and has met the needs of expanding the availability of use with my new Canon. The store manager was very helpful and led me right to where I needed to go to obtain this item. Overall, the experience with the lens and the store has been excellent.

Thankful they brought out this adapter, so that I can still use my other lenses. Easy to take on and off and fits snug.

This adaptor allowed me to use my current EF lenses so I didn't need to purchase all new lenses to use on my new Canon R7 RF system. I was skeptical about the functionality of it but found that all the features of the camera work perfectly with the EF lenses including the excellent autofocus system of my camera.

Excellent build quality. It fits perfectly between EF-S/ EF lenses and RF port with all the functions of native RF lenses. The fit between lens and the adapter is not too tight or too loose. I would recommend this adapter for the intended purpose.

We bought the Canon - EOS R50 4K Video Mirrorless Camera with RF-S18-45mm f/4.5-6.3 IS STM Lens - Black and this was a plus since we had an old canon and wanted to continue using our old lenses.

This was a gift for my son he loved it he enjoy doing photography so this was a big help for his new camera

Exactly what I needed for my canon m50 mark ii. I’m new to real estate photography and bought a wide angle lens without realizing it wasn’t compatible. This worked perfectly so that I could use my new lens with no issues! Pictures turn out clear.
