English: A Sputnik medium format stereo camera. The twin lower lenses take the picture, recording it on 120 roll film, while the middle lens is used to compose the shot through the top-down viewfinder. The lever on the front at the bottom of the camera is used to control the aperture of the two lenses, while the levers on the side of the lens are, going anti-clockwise from the top, the shutter release, timer and shutter speed selector. The gears connect the three lenses, so that focusing one moves all three in unison. 120 (medium format) roll film provided for scale.
