Coupling a camera with binoculars was not uncommon, especially in the era when subminiature cameras were all the rage. This one, made in Japan by the Toko Photo Company, took 16mm film in its own unique twin cassettes. Rings on the rear of each lens focused the binoculars, which acted as the viewfinder. The camera was mounted above the binocular lenses with its own lens between them, focused by a ring on the barrel. Behind that, another ring set apertures of f/4.5-16. Shutter speeds of 1/25-/1/100 second were set on a sliding control beside the shutter release. This was one of the better subminiature binocular cameras.
