The Fujifilm GA645 Professional is an autofocus medium format camera introduced by Fuji circa 1995. It uses 120 / 220 roll film and captures images in a 645 format. It is succeeded by the Fujifilm GA645i, released in 1997.
The GA645 uses a 60mm f/4 lens while the similar GA645W uses a wider 45mm f/5.6 lens. The shutter is electronically controlled with speeds of 2 sec to 1/700 of a sec. but for the aperture range of f/4 to f/9.5 can only go as fast as 1/400 of a sec. smaller apertures of f/11 and f/22 can use the faster shutter speeds. A electronic self-timer is available with a delay of 10 seconds.
The finder is in a portrait format orientation instead of the more common landscape format. It has bright lines and parallax correction. It has additional information including aperture, shutter speed, focus distance (m or ft), as well as exposure meter information.
The exposure system is a center-weighted system using a silicon photo diode. It has a range of 3 to 19 EV (ISO 100). It is not a TTL type system. The meter settings supports film speeds of 25 to 1600 ISO in 1/3 increments. Exposure modes include (P) programmed auto, (A) aperture priority, and (M) manual exposure mode. Exposure modes can be changed with the dial near the eyepiece. Exposure and date time information can be imprinted on the film outside the photo area.
The film transport is motorized with a automatic film advance. It also supports fully automatic film loading. This does not require matching the backing paper start mark to a body indicator for first frame loading. The main up and down setting dial can be used to rotate the take up spool for easier leader insertion. Close the back and the camera detects the first frame. A electronic warning beep is emitted on the last frame of the roll. This sound can also be disabled. When the last exposure is complete, the film is wound automatically to the take up spool. Mid-roll rewind is possible with a button on the base of the camera. The camera is powered by 2x CR123A battery.
Fujifilm GA645W
The Fujifilm GA645W or Fuji 6x45Wide is another available version sharing a similar body specifications but with a 45mm f/4 lens.
