By no means am I a pro photographer so take this with a grain of salt. I’ve been using it to adapt Yashica ML lens onto the Sony A6000. my initial thoughts after using it for the first 2 weeks are overall good but do have some criticisms. The adapter it self is solid, holding it you can tell it’s an all aluminum construction. Installing the adapter onto the camera was easy and adding the lens was a breeze. Its a basic adapter so no auto focus, no image stabilization, and no additional adjustment rings. This is not my criticism but adding that in for good measure. My criticism lies in that there is a bit of a gap between the adapter and the camera body. It’s a small gap, and I mean small, between the camera body and adapter. It’s not too big of a deal and haven’t noticed light leaks but it does cause a slight wiggle. For reference the gap between the lens and adapter is about the thickness of a sheet of printer paper. Image quality will depend on the lens itself but it does take some time to learn to use a manual focus lens. The test photo was taken to see accuracy. Toy was set 4ft away and shot at f3.5 using 75mm lens at 4ft focus marker on lens. Overall I would buy this adapter again I think it’s a great deal if u want to give new life to an old lens.
