My workhouse lens are the Tokina´s 11-16 / 28-70 / 80-200 all at f2.8 with Minolta/Alpha mount, really tough guys. I use with La-EA1 on the FS100 and the Nex 5n and native with the A77, my primary lens are Canon FD mount, . But is you want a better compatible system i think the Nikon lens are the best all around, can be used on Canon and Sony cameras.
