Many of the Life photographers shot with a Contax, including George Silk, Bill Ray, David E. Scherman,Yale Joel, Hank Walker and others.

And of course it should be remembered that Henri Cartier-Bresson often used a Leica with a screw-mount f/1.5 Zeiss Sonnar.

The f/1.5 Sonnar (prewar or postwar) is one of the finest lenses of all time.
