If you have manual focus Minolta lenses, then they are not usable on anything other than other manual focus M35mm Minolta SLR's.
If they have the Minolta autofocus mount then they will physically fit onto any of the current range of Sony Alpha SLR's and also the discontinued Konica Minolta digital SLR's, but there will be some issues:-
- there will be a 1.5x magnification factor due to picture cropping caused by the digital image sensor being smaller than a 35mm film frame. As an example, a 70-200mm zoom lens will produce an image equivalent to that of a 105-300mm lens if mounted on a 35mm camera. Lens apertures are not affected by the 1.5 crop factor.
- Earlier Minolta AF lenses relied on the camera body providing the autofocus motor. Later Konica-Minolta and Sony models lack this motor so the lens can only be used in manual focus mode.
- If you have a later SSM (SuperSonic Motor) equipped lens and want to use it on an Minolta Alpha/Maxxum/Dynax 9 (different model names in different countries), the camera needs a complete additional circuit board which is no longer available.
- Later Sony Alpha SLR's have far greater electronic communication with the lenses used. Many Minolta lenses will not be compatible and as Sony don't support legacy products there is no fix.
In short, Minolta MD lenses (manual focus) can't practically be used on any modern digital cameras, and Minolta Alpha (autofocus) lenses will physically fit onto a Sony Alpha digital SLR, but will act as if magnified and may not autofocus or work at all on a Sony SLR. But there's no harm in trying.
Sorry there is no absolutely definitive answer for you, but I hope that you now understand why and that you take a moment to rate my reply.
