The Koni-Omegaflex M (from 1969..) is an unusual twin lens 6x7cm camera. A nice feature is the use of the same film magazines as the Rapid M. You can add an optional reflex viewing attachment. Besides the 90mm lens, you could also buy the 135mm f/3.5 Hexanon and the 180mm f/4.5 Hexanon lenses in this TLR mounting too. As the posters note below, the original goal was to compete against the then popular Rollei TLRs, while offering interchangeable lenses and the “ideal” or 6x7cm format (less cropping on prints) plus the convenience of interchangeable film magazines. Great idea, but a heavy camera that probably got clobbered by the switch to SLRs like Hasselblad and Bronica in the 1960 timeframe?
