Hasselblad 50mm f/4 C and CF (1964–1989)
A pair of Zeiss-made wide-angle lenses for the Hasselblad V system, two generations, both with integrated shutters and flash sync at all speeds.
Overview
The Hasselblad 50mm f/4 C and its successor, the CF, are wide-angle lenses for the Hasselblad V system. Zeiss made both, under the Distagon name. The C version ran from 1964 to 1982 in chrome and black T✻ variants. The CF version followed from 1982 to 1989 with a bayonet filter mount and an updated shutter. The diagonal angle of view is 75°, roughly equivalent to a 28mm lens on a 35mm camera. Both have a leaf shutter, so flash synchronization works at all speeds, including 1/500s. That was a hallmark of the Hasselblad system.
