[raay04]

Hello folks , i want to buy this chinese made tamron AD2 to pentax screw mount adapter , so wanted to know if anyone here is using it or not . I mainly want to know does it have guaranteed Infinity focus and does the lens markings align properly after mount the lens on camera / M42-nex adapter.

I bought one for my M4/3 camera,it does not align at 12oclock its way out...which annoyed me at first,but for the price I can live with it. Infinity was ok
