The Zunow 50mm f1,1 lens

The Zunow 50mm f1,1 lens, made in Leica screw mount in very small numbers in the mid- to-late 1950s. The Zunow firm was a small Japanese outfit known for fabulous lens designs that were costly to produce. Eventually bought out by Nikon, the 50mm Zunow f1,1 speed-king is rarely seen for sale and is one of the rarest Leica screw mount lenses out there.
