I just got the adapter and directly tried: Minolta MD Rockor 50 at Nex. 6 The adapter is seated on the camera without play, the lens wobbles unfortunately quite easily. I'll probably keep the adapter anyway, because it is very cheap and my Minolta lenses relatively old, so the investment in a better - and thus more expensive - Adapter for now does not make sense. Overall, I forgive 3/5 stars: The adapter works with swabs.
