Konica Koni-Omegaflex (1968–1975)
The Koni-Omegaflex M is one of the stranger entries in Konica's medium-format lineup. It's a twin-lens reflex that shoots 6x7cm on 120 rollfilm (220 also works), with interchangeable paired lenses mounted in their own shutters. The standard lens is a Hexanon 90mm f/3.5. A 135mm f/3.5 Hexanon was offered as the alternate, and Konica produced that 135mm set only from 1972 to 1974. The camera is manual focus with a waist-level finder. One forum user said it looks "similar to the Mamiyas," which makes sense, since Konica sold the entire Koni-Omega Rapid line to Mamiya in 1975. The Omegaflex M clashed with Mamiya's own TLR lineup, so it was discontinued that same year.
The 1968 date comes from a Russian-language source (Photar.ru). The 1975 discontinuation comes from an owner's account on Flickr. So the production window is approximate but reasonable. The camera is described as rare. A complete auction set, two bodies plus four interchangeable twin-lens assemblies, hammered at €2,400 including buyer's premium at Leitz Auction. A parts-only lens has sold for C $88.43.
Surviving information on this model is thin beyond that. The sources list no shutter speed range, no dimensions, no original price and no metering details. Owners report shooting it handheld at f/11, using it with Ilford FP4+ developed in Perceptol, and pairing the 135mm lens with Fuji Pro 160S in 220 format. One eBay listing noted "shutter working, glass has some light cleaning marks and light internal haze, wind mechanism sticky and needs a little attention" - a pretty typical used-TLR caveat.
