I just bought a 50mm f1.4 from minolta Mount A. Everything works fine but i cannot change the aperture, so now I'm wondering if the lens is broken or if i have to buy some sort of mount a to mount a adapter to get the apertrure to work. Thanks!

The Minolta 50mm f/1.4 has a mechanical aperture ring. Are you using that? If you look through the lens, do you see the aperture size change physically if your turn that ring? If the camera says -- for the aperture value, this means there is no electronic coupling with the lens. Set camera to A or M mode and set aperture manually with the aperture ring on the lens.
