It had automatic exposure driven by a selenium meter, with a manual override to set the aperture for flash. The Prontormat-s shutter had flash sync was by a PC socket hidden under a rotating cover on the top plate. It had a fixed 50mm f/2.8 Tessar lens, marked with focus zones on the top and a distance scale underneath.
Its Zeiss code number was 10.0651.
