The Icarex 35 is a family of fairly basic 35mm SLR cameras based on the Voigtlander designs and produced by Zeiss Ikon after the merger with Voigtlander. The first model - Icarex 35, a camera without an exposure meter, was introduced in 1966. In 1969, the Icarex 35S with TTL (stop down) exposure metering appeared. Meanwhile, an interchangeable pentaprism named CS was developed for the Icarex 35, which also provided TTL exposure metering.
The lenses for this system were based on Voigtlander designs, manufactured by Carl Zeiss and had an original bayonet mount. The limited set of lenses did not contribute to the popularity of the system, so in addition to "BM" cameras with bayonet mount, "TM" cameras with M42 screw mount were also introduced.
In 1971, the SL706 camera was introduced, which provided open aperture metering with Carl Zeiss lenses.
