The Seagull GC-107 is one of the top Seagull medium format cameras. Like the GC-105, 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 crank advance and separate shutter speed and aperture levers.
The GC-107 has all the features of the GC-105 but includes an improved 4 element "picture taking lens" plus a shutter lock lever. The mechanical lens shutter design provides flash synchronization at all speeds up to 1/300 second and there is also Bulb exposure. This camera also features a cold flash shoe and PC terminal for external electronic flash connection.
