I think you may have inadvertently answered my question...I use a Minolta Maxxum 7 and am looking to buy the Sony A100 for my first digital SLR since I own 4 Minolta mount lenses already and am looking to go pro soon. I however need another flash as the toggle on/off switch on my old one is busted, so it turns on and burns through batteries if I don't remember to remove them. I was looking at either buying a Minolta 5600 on ebay or getting the new Sony 56 flash but I couldn't find anywhere that the Sony brand would work with my 2 Minolta Maxxums. If it is just a rebranded Minolta, then I guess I should buy the Sony.....
