Tenax Automatic

In 1960, Zeiss Ikon Stuttgart reused the Tenax name on a small viewfinder camera named Tenax Automatic. It has automatic exposure driven by a selenium meter, with a manual override to set the aperture for flash. The Prontormat-s shutter has flash sync, by a PC socket hidden under a rotating cover on the top plate. It has a fixed 50mm f/2.8 Tessar lens, marked with focus zones on the top and a distance scale underneath.
