Zeiss Ikon Contarex SLR mount, 1950s-1970s | 35 mm SLR
Contarex was Zeiss Ikon's ambitious premium 35 mm SLR system. The original camera appeared at the end of the 1950s as an elaborate, expensive answer to the professional SLR market, and the lenses carried Zeiss's high-end optical identity into the reflex era.
The mount's lens family includes Planar, Distagon, Sonnar, Tessar, and specialty optics built to very high mechanical standards. Many designs show Zeiss adapting familiar names and correction priorities to the longer register and mirror clearance required by an SLR.
Contarex never became a mass-market standard, partly because the bodies were complex and costly just as Japanese professional SLR systems were accelerating. It remains one of the clearest examples of Zeiss translating its rangefinder and large-camera heritage into a no-compromise 35 mm SLR system.
Flange focal distance 46 mm, bayonet mount. 0° at 12 o'clock from the camera front; the lens-side view is the horizontal mirror. Dotted strokes mark photo-scaled or schematic (not-to-scale) dimensions.
