If the Minolta 35mm camera's you already own are any one of the "Maxxum" serie's, the lenses you already own for these camera's should all be compatable with the Sony alpha!.What model camera's are they?If they have removeable lenses they are "SLR" camera's (single lense reflex)."DSLR" camera's are very simular to these..."D" simply represent's "digital". If you already own any "Minolta A-mount" type lenses, I would recomend Purchasing the Alpha camera body only (apr $700) wich would allow you to use your existing lens inventory. If you decide you want a more simple camera (without removeable lens),the Canon A710IS can be had for less than $400 and also has an auto stabilization mode...
