EF/EF-S Lens Mount Adapter Compatible with Canon EF/EF-S Lens, Auto-Focus Lens Converters Ring, for Sony E Mount Mirrorless Cameras Series A9 A7R5 A7R4 A7R3 A7R2 A7R3A A7R4A A7M3 A7M2 A7R A7S2

Wow. I guess it works great on Sony APS-C body. Somehow, the qualities of my Sigma and Tamron Canon lenses are better on the Sony ZV-E10 than on my previous Canon 50D. I think my Canon 50D was the problem. I always thought I got a bad batch of lenses.

Excellent! Works very good!

Excelente producto... Recomendado 100%!!!

Did not work pairing my sigma 24-70 ef lens to my Sony a7iii. Would not read. Tried to follow the instructions, got it to read something but couldn’t change the f-stop nor autofocus.

Really solid for the price! Works flawlessly with electronics and noticed no effect on focus tracking capabilities. Mounts securely with only a tiny bit of play (expected for the price). Performs just as well as the $300+ adapters. Would definitely buy from this brand again for my other cameras.

Again the product deserves five stars but it's ruined by ASSazon's HORRIFIC delivery methods. Again my package ended to at someone else's house. Delivery is part of the product experience especially when you're not going to the store and buying it yourself. And the delivery keeps being botched. Clearly a multi-billion dollar business doesn't know how to use GPS but I digress.Fantastic adapter. Clicks on buttery smooth for the E-mount side. No pin friction or snagging. Very nice and satisfying.The EF-mount is just as smooth. My old Canon lens fits perfectly onto the adapter and THE AUTOFOCUS WORKS!!!!The auto focus was my biggest concern. Going from Old Canon gear to a new Sony camera, I was expecting the autofocus to be slow or not very reliable. The opposite was true. The autofocus works just as reliably and just as quickly as my normal Sony lens. BIG thumbs up for that 👍.The only feature that doesn't seem to do anything is the C/P button. Not sure what it's supposed to do but it doesn't seem to do anything. I'm going to have to take another look at the manual. I'm also going to have to take a look at the website for any firmware updates because I see that there is a port on the adapter. Maybe they have some new firmware making the adapter even better.Overall, super solid product that I can't wait to put through the ringer.

This sav es me from buying all new Sony lenses and using the Canon L-series lens that I have.

I was very surprised by how well this worked. I picked it up so I could rent and borrow some higher-end Canon lenses for some video projects. I was amazed at how well the autofocus worked with my Sony camera. This was worth the investment just to have the opportunity to use more lenses for different projects.
