The Fuji GSW690 is a fully mechanical medium format rangefinder camera, designed for professional use and introduced as the first iteration of the GSW690 series in 1978. It features a fixed EBC Fujinon SW 65mm f/5.6 lens (providing a field of view equivalent to 28mm on 35mm film) and uses a Copal-type leaf shutter with speeds from T and 1s up to 1/500s. The camera shoots 6x9 cm images on 120 or 220 roll film, with selectable frame counters for 4, 8, or 16 exposures per roll, depending on film type. With no built-in light meter and entirely manual controls, the GSW690 emphasizes mechanical reliability and photographic basics. The viewfinder is clear with a vernier-style rangefinder patch for focusing, and the camera body, weighing approximately 1485 grams, is constructed from a die-cast metal frame clad with some plastic. Known for its large negative size and sharp fixed lens, the GSW690 is popular for landscape and panoramic work, and its straightforward operation makes it a favored tool for film photography enthusiasts seeking high image quality in a rangefinder format.
