Customer Ratings & Reviews

awesome adapter, I use this with a canon r6 and a ef 1.4 35mm lens. no issues!

This is so simple to use and works great on my aftermarket EF lens. fast delivery from best buy love this adapter. highly recommend it

I am able to use all my canon ef lenses using this adapter. saved lots of money! no issues at all

This will revitalize your old EF lenses. This is a must unless you are a millionaire and will buy all the RF lenes.

Works without any issues with my 50mm and 17-50mm sigma EF - EF-S lenses. Not much else to say, durable build, shipped quickly, and easy attachment.

Allows me to use all of the lenses I already have. A must have if you are using the new mirrorless canon cameras.

This is a great adapter to use on the Canon R6 with my EF lens. They work well together.

Works great. All of my EF lenses are working better than before with the mirrorless camera.

My EF glass works perfectly with this adapter with the R5. Autofocus, including face detect/eye tracking, works perfect!

Good and helpful toy for my new camera excellent resolution

the adapter adds a tiny bit of length to EF lenses, but works great. I found no problems with camera communication to the lens or auto focusing.

PRO: Works excellently and without any issues (so far), decent price CON: none so far

Great product! No need to buy more expensive versions! This works perfect with my R5 and Ef lenses.

This is exactly what I need so that I don't have to part with my collection of Canon EOS lenses. I chose this standard adapter over the more expensive ring mount with the customisable control ring, which I was not wanting. It's a little stiff attaching to the camera or being attached to by the lenses, but I think that may abate as it breaks in from being new.

This adapter does exactly what it is supposed to do... allows you to seamlessly use your EF lenses on an RF mount camera.

I got my order 2 days early which was awesome. Adapter works perfectly.

Excellent converter to adapt the old stuff EF lens to RF mount. Worked well with my 70-300mm L EF lens. Though eventually I returned this for the one with the ring, I still think this is an excellent adapter.

I bought it to use Sigma lenses on a Canon R8, and it works perfectly. Highly recommended.

This lens mount adapter was a huge cost saver! I recently upgraded from a Canon 7D to an mirrorless R6 model. Without this adapter I would have to purchase all new lenses which would have cost me thousands! This adapter allows me to use my current lenses with ease! This works well and is highly recommended to anyone who might have made a switch like I did.

Works great! I used it with my r5 and r6 om a Sigma 120-300 2.8
