I bought this adapter to connect my old Canon FD lenses on a cheap Sony A3000 can, what also works very well. The adapter is precisely between the camera and lens, nothing wobbles, nothing stuck, basically as you would expect. At infinity setting is true in my experience as: Infinity is now just beyond 3 meters on the scale on the lens, ie, the long range can be provided easily sharply, just when the lens actually (ie to infinity) focused until it stops, is of course nothing more sharp. I can live with that. What also is a small flaw: The ring with which the iris is closed on the lens, scratched during the adjustment and is a little stiff. We'll see if I there with some bearing grease can help.
