Customer Ratings & Reviews

It’s a very dimple device that works as described.

I had trouble finding this in stock, but it's now available! I purchased this after using ef mount lenses and then recently purchasing the canon RP mirrorless camera. Adapter works great and saves a lot of money so I can use my EF lenses

This adapter works great on my Canon R6 Mark II. Having recently converted to mirrorless, I had a nice selection of EF mount lenses that I needed to use. This adapter made that possible with the new camera. No issues communicating between camera and lens and auto focus works perfectly. Highly recommend.

Love the ease of this adapter. Haven't had issues with my ef lenses and this adapter for my mirrorless. Definitely recommend!

Combined with my R5 this works great for my EF lenses. This is the less expensive version that doesn't have the control ring. In hindsight, it might be worth the extra $100 for that functionality.

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

This adapter works great! I use it on my Canon EOS RP with Canon EF lenses. The auto focus is quick and the image quality is excellent.

I wasn’t sure how I was going to use my old lenses but this adapter works really well I have not had a problem since having it!

This lens adapter saved me thousands. I thought I was going to have to purchase all new lenses. All of my EF lenses work seamlessly.

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!

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

We purchased this so we could use our EF-S lenses on our Mark III R6, so glad we did so we don't need to buy new lenses

This was a great product. I have have had no issues.

This is a very high end adapter for my new Canon r8, any Ef lens I have it automatically recognizes it, Way better than something cheap on amazon!

Works exactly as it should. Allows me to mount all the EF-Glass from my previous Canon camera right onto the R6 without any issues. The only real hitch is if you have any RF glass you'll soon want to upgrade all your EF lenses and scrap the adapter since you won't need it anymore. Simply put...if you have a bunch of EF lenses that you love and plan on holding onto then this adapter is a no brainer if you're upgrading to a mirrorless Canon like I did. If you think you'll be selling off your EF line to upgrade to RF glass then maybe put the $100 you would've spent on the adapter towards a new lens.

Perfect exactly what I needed. Use it frequently and it has been amazing.

works great with my Sigma m, happy for my purchase.

I recently upgraded my Canon T6i to Canon R7. I of course didn’t want to have to purchase all new RF lenses and decided to explore my options. Thats when I found this adapter. This. Adapter. Is. Amazing. It lets me use all of my previous EF lenses with easeand its become a part of my daily setup.

This works wonders. I had to buy this because my lens I brought and it didn't fit so I had to buy the adapter.

Great tool to use all my EF lenses on my R-mount camera! Great performance
