The Icarex 35 was a family of fairly basic 35mm SLR cameras based on the Voigtlander designs and produced by Zeiss Ikon after the merger with Voigtlander:
Icarex 35 - a SLR with an original bayonet mount, mechanical shutter with top speed of 1/1000th of a second, without a built-in exposure meter but with interchangeable finder attachments;
Icarex 35S - the same model but with a built-in CdS TTL stop-down exposure metering and match-needle f-stop setting in finder. The prism finder was also available as an attachment for the Icarex 35.
Lenses for this system were based on Voigtlander designs and produced by Carl Zeiss. The limited set of lenses did not contribute to the popularity of cameras, so in addition to bayonet-mount models, "TM" cameras with the M42 screw mount were also introduced.
The SL706, introduced in 1971, was the last camera designed by Zeiss Ikon. It was based on the Icarex 35S TM but provided TTL open-aperture exposure metering with Carl Zeiss lenses designed for Icarex 35 TM series.
