The Contaflex series is a family of 35mm leaf-shuttered SLR cameras, produced by Zeiss Ikon in the 1950s and 1960s. The name was first used in 1935 on a 35mm Twin-lens reflex camera, the Contaflex TLR also by Zeiss Ikon, the -flex part in the name referring to integral mirror for the viewfinder. The first models, the Contaflex I and II have fixed lenses, while the later models have interchangeable lenses, and eventually the Contaflexes became a camera system with a wide variety of accessories.
The Zeiss Ikon AG factory in Dresden was almost totally eradicated by the end of World War II. The remains were gathered in Stuttgart, then in West Germany. Only a few prototypes were rescued. Both the lens- and most of the camera production had to be rebuilt from scratch. This was at the same time a tremendous opportunity for the company to develop completely new products. In this situation, ZI was in desperate need for new cameras models. Yet, it should be remembered that almost all the popular cameras manufactured worldwide, have their origins in Germany; these are typically the 6x6 TLR 1928 Rolleiflex, the 1925 Leica and the 1932 Contax 35mm rangefinder cameras, as well as the 1936 Kine Exakta and the 1949 Contax S 35mm SLR cameras.
