Topcons early fifties 35mm viewfinder and rangefinder models: The Minion 35 and Topcon 35a viewfinders and the Topcon 35S and 35L rangefinders. These sample the following up of the market request to 35mm cameras, and the development out form the Minion folding camera in to an up to date 35mm rangefinder. Not many of these cameras were produced, but particular with the Topcon 35L with its relatively fast lens Topcon managed to produce a very fine rangefinder camera.
The Topcor aux lens set for the Kodak Brownie 8mm film camera is a curious and rare sample of Tokyo Kokagu lens production for other companies. Most likely these sets were only distributed on the US market.
