This camera belonged to my late father, it is one of the more sophisticated 35mm Zeiss cameras, and was first made in the late 1930s. Unusually for a 35mm camera, it takes sqaure negatives, menaing that you get more then 50 exposures from a standard 36 exposure roll. The f2 40mm Sonar lens has a coupled rangefinder, and the Compur shutter gives a full range of speeds.
I loaded it with ISO 200 Fomapan black and white film.
