I used this adapter for my A6000 camera and mount it with sigma DC 17-70mm Macro HSM and canon 70-300mm IS USM lens and works just fine but the auto focusing is very slow. I recommend manual focusing when using this adapter.

Connects fine, but autofocus only works on 1 out of 3 lenses.

Well build, but the adapter auto focus function does not work with Canon prime lens (fixed focus lens) like the Canon EF 50mm f/1.4 USM.

Excellent adapter, works brill on my NEX 5N. AF works but is super slow as expected. MF is excellent with the Sony using the cameras focus peaking. Having a blast with this adapter and my Canon lenses, getting great results with my "Nifty Fifty" and 85mm 1.8..........

Received the adapter earlier than expected and proceeded to attach it to my newly purchased Sony a 6000 ( what a great little camera ) the tried all my Canon lenses and each one in turn operated as normal, the auto focus was much quicker than i thought it would be and the image quality was amazing.

Bought this adapter hoping that it would work on my Sony A7 with my canon glass. for one it doesnt allways focus so you have to power off camera, wait 5 sec and then turn on and hope that it works. Two, when locks focus then the focus is not accurate.

The item fully meets my expectations and has worked well with a variety of Cannon lenses. Thank you very much GR

It's good adapter. Solid built. But for my canon 28-135 f3.5-5.6 don't work aperture level. The (f) numbers on the screen are changing, but nothing changes on the lens. Maybe my lens is broken.

Please read this review in conjunction with the other reviews. I do not want to reapeat things already mentioned by other reviewers.The adapter funcions perfectly on Nex cameras, it vignettes a bit on the a7 but this is no surprise because it was designed for the APSc sensor.

23-12 EDIT: Even more impressed with this adapter now. I recently tried it with a friends Zeiss and Sigma 3rd party Canon mount lenses and it operates aperture and AF on both lenses. Some of these adapters will only work with Canon EF lenses.
