Customer Ratings & Reviews

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!

This adapter works perfectly. I'm able to use my older Cannon lenses. This easily cost way less than replacing lenses would have cost.

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.

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

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

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.

great communication and easy purchase. product works great

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 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.

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

Does exactly what's needed. I haven't had any connection issues that I've had with 3rd party lens adapters in the past. The AF on my EF lenses are even faster on the R5 than on the 5D.

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 way to use my old lenses until I can purchase new ones

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!

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 as described, and works great. No problems!

Having the EF 70-200 F2.8 II IS USM and the EF 100 F2.8 Macro IS USM I needed this adapter to pair it with my R8. It works and the photos I have taken thanks to this adapter are crisp and clean

Works as advertised. Lets me use my ef/ef-s lenses on my new R10 with no issues.

This item was needed and a great purchase as i have older lenses.

works flawlessly adapting EF type lenses to the EOS R cameras. EF lenses seem to work even better on the newer R6 camera
