Produced in small numbers, the Contarex Super Electronic (or Contarex SE) was a focal-plane shutter SLR derived from Zeiss Ikon's Contarex Super. It was introduced in 1970. The SE's unusual feature was a shutter whose timing was controlled by an electronic circuit, described in the manual with a schematic diagram. An accessory-shoe mounted Tele-Sensor could connect to a socket alongside the lens mount and control this shutter speed steplessly for any given aperture (previously selected on both lens and sensor dial). This was one of a series of various electronic accessories and cables made for this model.
A number of focusing screen options could be user-exchanged via the lens throat, without affecting the TTL metering cell located behind the reflex mirror.
