The Simda Panorascope was a stereo camera taking either 120 stereo pairs or 240 monophonic photos on a 25 ft. roll of either 16mm or double-8 cine film, made by Parisian company Simda c.1955. There was a switch on top of the camera that the photographer could set to "M" for mono or "S" for stereo. Processed transparencies were mounted in proprietory Panorascope mounts, which could be viewed through one of two viewers offered by Simda. One viewer was basic and of the 'steal the light' variety, with the other viewer being a battery-powered Deluxe affair. The Deluxe model was designed to also 'steal the light' if batteries weren't available.
