Fujifilm GA645i
The Fujifilm GA645i Professional is a autofocus medium format camera introduced by Fuji in 1997. It uses 120 / 220 roll film and captures images in a 645 format. It succeeded the Fujifilm GA645, released in 1995.
The body of the camera is looks nearly identical to the previous model, but it now supports an additional shutter release button on the face.
The GA645i uses a 60mm f/4 lens with a 52mm filter thread. It has a minimum focus distance of 0.7 m. 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 second. Smaller apertures 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, so exposures using lens filters need to be recalculated. The meter settings supports film speeds of 25 to 1600 ISO in 1/3 increments. Exposure compensation is available and can be changed from ± 2 EV in ½ incremnts. Exposure modes can be changed with the dial near the eyepiece. Exposure modes include (P) programmed auto, (A) aperture priority, and (M) manual exposure mode. Also on this knob is ISO; use the up and down dial on the shoulder to change a majority of settings. Exposure and date time information can be imprinted on the film outside the photo area.
The GA645i can capture 16 exposures on 120 and 32 exposures on 220 film. 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. Bar coded films is also supported, this allows the camera to detect the ISO speed of the film automatically. 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.
