This camera is the first 35mm SLR ever manufactured, although it's contested by German Kine-Exakta.
Mass produced model of the GELVETA. The back of the camera is like the CONTAX. The system of changing film was by 35mm automatic film cassette designed especially for the SPORT. A fully loaded film cassette gave 50 exposures 24x36. The front of the viewfinder was engraved with the GOMZ sign and the glass finder was coloured yellow/orange. The viewfinder strap pins replaced by a decorative rectangular ring surrounding the eye-piece. The top-plate held first by 6 screws and then by 2. In spite of the bayonet, no other focals other than the f3.5/50mm.
Please note that the cassettes pictured here may not be original to the Sport camera
