> I know which one for Cartier-Bresson, but what about Winnogrand and Salgado?
Winogrand used a 28mm almost always, and Salgado, when I heard him interviewed, said he used a 28, 35, and a 60. --Mike P.S. Anyone closely associated with using a Leica rangefinder almost by definition only uses a few focal lengths--no zooms, nothing over 135mm if that, no macro (no, the DR doesn't count <s>).
