Leicaflex 18x24 Half-Frame Prototype 1965

Leicaflex 18x24 Half-Frame Prototype profile 1965

A unique design by Helmut Müller, the LEICAFLEX 18x24 camera and matching Summicron 2/35mm lens is completely different to all other Leica cameras. It is equipped with a Rotor shutter, the mechanics resemble the Olympus Pen F half-frame cameras. According to the development order from April 1962, Leica started to built a half-frame SLR prototype. In January 1967 the project was stopped, due to the worldwide sales slowdown of half-frame cameras. This is the only completely finished camera built by Willi Franke in 5 years of development. Unique and sensational collectors item, historically very important.
