Konica I Type Cs camera
The Konica I is a 35mm film rangefinder camera made in Japan by Konishiroku circa 1950. This is a Type Cs, identified by the Hexar 50mm f/3.5 lens set …
This was the first camera to use Agfas ratchet operation system. The camera opens to the left by sliding a switch on the bottom. Once a photo was taken, the camera has to be pushed back together and out again, which advances the film and cocks the shutter. The noise the camera makes during opening and closing led to it being called the ritsch-ratsch camera in Germany.
The camera is still usable. Lomography make a 110 film cartridge that fits it:
