In 1978, the designer of the Rollei 35, Hienz Waaske, sigined a contract to design a Minox 6x45 camera, with many of hte features of the Minox 35.
The aim:
FILM: 120 roll film (16 exposures), nominal size 4,5x6 cm.
FOCAL LENGTH: 60-65 mm
MAX.APERTURE: 2,8.
EXPOSURE: Aperture priority with automatic electronic shutter and shutter speed indicator in the viewfinder.
FILM-TRANSPORT: Only no turning knob!
RANGE-FINDER: Dual image, better still, split image range finder.
VIEWFINDER: Bright frame viewfinder with automatic parallax balance, rangefinder measuring field, time and shutter indication.
SIZE: Flat! (max. 45 mm greatest thickness, better 42 mm). The camera should easily fit into the side- or inner pocket of a normal man's jacket. Very rounded edges.
BODY: Matte-black varnished synthetic material like the 35EL, no leathering or scarring.
WEIGHT: 300-350gr.
It was never built, and Minox bankruptcy in 1988 finished off the idea. The new owners of Minox were shocked when plans and development costs of this project was found.
It would have been considerably smaller than the Fuji GS645 folding camera. A digitlal version smaller still.
