I don't have the Minolta 80-200 f/2.8 APO G, I have the 200mm f2.8 APO G. However to answer one question, the micro adjustment is dependent on both the lens and the camera. Adjusting the lens on one camera will not make it correct for another camera. Micro adjustment is a bit of a hit and miss affair. especially for a zoom lens. So don't expect miracles. Adjust it at the focal length you use most often and leave it at that.
One other point about all these Minolta white lenses is that some, not all, can have poor paint which chips easily.
