Probably more than I should sensibly have ...or realistically need. To wit: F2AS w/MD2-MB1 x3, F2A w/MD2-MB1, F2(DE-1) w/MD2-MB1 x2, F2 (DE1 - no drives) x3, F3 w/MD4, F3HP w/MD4 x2, F4s (my least loved NIkon) and F5 x2. And thinking about looking around for an F3P/MD4 in really, really good shape...
