The Busch Verascope F-40 is a well-made, 35mm stereo camera produced by French camera maker Jules Richard and marketed in the United States by Busch in the 1950s. Prior to the Verascope F-40, Richard had a history of being a pioneer in the design and production of stereo cameras and stereo photography equipment. The F-40 was a continuation of the popular Verascope line, which had begun over a decade earlier with a glass plate camera that made 45mm x 107mm exposures.
The Verascope F-40 was built to use standard 35mm film, allowing it to be much more accessible to hobbyist photographers. It exposes a pair of 24mm x 30mm frames simultaneously, but like other high end stereo cameras of the time, a dark slide behind one lens can be closed to allow the Verascope F-40 to produce single images. The camera uses a pair of 40mm f3.5 Berthiot lenses with a guillotine-style shutter capable of speeds from 1 second to 1/250, plus Bulb and Time. Aperture selection is done via a dial on the face of the camera and allows for f-stops between f3.5 to f16. A focus dial is centrally located at the back top of the camera and moves the entire front lens standard focusing both lenses simultaneously. Separate viewfinder and rangefinder windows provide for framing and accurate focusing. Other than that, there is not much else to state about the Verascope F-40 in terms of its functionality. It is considered one of the better designed stereo cameras for the mid 20th century, competing with the Stereo Realist. Though unlike the Stereo Realist which can easily be found, the Verascope F-40 is a pretty uncommon camera and fetches much higher prices.
