I have bought a Sony A100 and I have found out that my old flash doesn't fit, my hammer gun won't fit either because there is no socket in the Sony to plug it in. Given that the Sony is a re-badged Minolta do they use the same hot shoe? Buying the camera and lens has left me skint and so I'm looking to buy 2nd hand. On ebay I have seen a 2500 dynax and a 5400Xi dynax, are these any good and will they fit on the A100? Thanks in advance, Dave..
