Contax I was a high end 35mm rangefinder camera made by Zeiss Ikon to compete with Leica models. It was released in 1932.
Contax II was released in 1936 and was the successor of the Contax I. It was the first camera with a rangefinder and viewfinder combined in a single window.
Contax III, also released in 1936, was a Contax II with an exposure meter. It was one of the first cameras with a built-in exposure meter.
After the war, the Soviet Union captured the tooling and drawings of the Contax as war booty, and transfered them to Kiev, where they began the production of the Kiev rangefinder camera, as such a continuation of the Contax.
At the same time, the Western part of the Zeiss Ikon company, based in Stuttgart, completely redesigned the Contax and launched the Contax IIa in 1950 and Contax IIIa in 1951.
Contax IIIa is the same camera with Contax II with a light meter. Compared to the prewar Contax II and III, the IIa and IIIa used the same lens mount with a completely re-engineered shutter mechanism, fresh body, and much improved chrome finish.
Earlier variation IIa and IIIa cameras, all the shutter speeds on the dial in were black, and called, Black Dial. like early Leica cameras.
The Color Dials were in production longer than the Black Dials, 1954-62 vs. 1950-54
The earlier black dial Conrtax IIa and IIIa have a peculiar flash sync connection then they have standard PC socket.
Contax IIa and IIIa is a professional quality system 35mm Rangefinder with large system of lenses and accessories, that some considered the best 35mm lenses during the 1950’s.
Contax IIa and IIIa has a superb mechanical fit and finish, many believe better than even the legendary Leica M3.
The lens 50/2 Sonnar, produced in West and East Germany, has excellent reputation.
Also made in uncoated pre-war Jena variation, black or chrome,
the latter variation is on my camera.
West German variation has nicely finished chrome barrel, East German variation has OK finish aluminum barrel. The color and engravings on the front of the lens of the West German post war versions are chrome with Zeiss-Opton, black with Zeiss-Opton, and black with Carl Zeiss.
