Will this mount to a Sony A7R ii?
As far as I know it will, I was not informed that Sony had changed the size of the lens mount on the new sony’s A7 models , that would be counter productive to any person owning a Sony lens!
Yes i have it mounted to my Sony A7iii and it's a very good quality adapter.
correctly using the menu system. The adapter does not have electronic contacts to transmit lens info to the camera body.
