DESC: The Seagull GC-104 is an inexpensive introduction into the world of medium format photography. This non-metered classically-styled twin-lens reflex camera is patterned in the time-honored design of older Yashicamats. Its lightweight simple design consists of a waist-level finder with pop-up magnifier, manual film wind advance and separate shutter speed and aperture levers. The built-in (non-interchangeable) 75mm f/3.5 Seagull lens produces surprisingly pleasing results. In addition to shooting in the 6 x 6cm format, the camera is supplied with a 6 x 4.5cm format mask which fits inside the camera and allows the photographer to obtain 16 exposures from 120 film
