Without seeing any questions, answers and reviews, I wasn't feeling confident when I was making the purchase. When received, I put it on my Canon lens to my Sony A7IV one by one, all of them worked perfectly, auto focusing is fast and accurate. Images taken from Sony A7IV are much sharper than from my Canon 6D.The only thing missing is that when the lens is put on "Manual focus", A7IV does not show the enlarged image on the view finder like Sony lenses do.Tested lenses are: 135mm f2, 70-300mm f4-5.6, 24-105mm f4-5.6 ,85mm f1.8, 17-40mm f4.The adapter does not have the rubber sealing ring so it’s not waterproof.The C/P button does not have any indicator, you cannot tell which mode it is in.There is a mini usb interface inside the adapter, but I found no mention of this in the user manual.Overall it works like it it says and it’s exactly what I was looking for.

Do not recommend. I bought this adapter for my Sony a7 iv to use with my 85mm canon lens on my Greece trip. Tried it the moment it arrived and no image was focused and I almost wasn’t able to get it off either equipment. I returned instantly.

It works like it should but switching the autofocus mode is very unreliable and confusing.

Used on a Sony a7iv, works exactly as expected to adapt Canon lenses.
