The KonicaAuto-Reflex of 1965 was the world’s first auto-exposure 35mm focal-plane-shutter SLR; hence the name. This new technology made it “the star” of the International Photography Fair in New York where it was shown, according to one magazine.
This model and its rarer, meterless companion the Konica Auto-Reflex P are the only models with “Auto-Reflex” as separate hyphenated words. These are also the only two SLRs that ever offered a choice of full- or half-frame exposures, switched by a lever on top of the camera. The frame size can be changed between 24×36 landscape and 18×24 portrait in mid-roll.
