LOMO 135BC Edit
Also called the Cosmic 135MS and LOMO 135VS (Cyrillic: ЛОМО 135ВС), this is a 35mm camera generally sporting an Industar 73 40mm f/2.8 lens and clockwork motorised film advance. It was made by LOMO in the USSR from around 1980 to 1985. It has some relation to the Smena Symbol - with a similar lens barrel and weather symbols, but is more heavily built with metal top- and bottom-plates and top-plate release.
Shutter speeds from 1/15 to 1/250sec + B, with hot shoe flash sync. The hot shoe, rewind release and rewind crank are in the base, with only the knob to wind the motor, the exposure counter and the square shutter-release on the top plate.
The top of the motor winder features an exposure calculator, where the user selects the film speed, then reads off the aperture against row of "scene symbols", and sets the shutter speed to an appropriate weather symbol. The lens barrel has a shutter-speed ring with weather symbols on top, and speeds underneath. The aperture is set via a ring around the front of the lens.
The motor is capable of giving short runs of multiple shots, at 2 or 3 per second.
