The Fujifilm GA645zi Professional is a autofocus medium format camera released by Fujifilm in 1998. A more uncommon black version was released one year later. It uses 120 / 220 roll film and captures images in a 645 format.
The GA645zi uses a 55-90mm zoom lens with a 52mm filter thread. There are four zoom lengths 55, 65, 75 and 90mm. In 55mm the aperture range is at f/4.5-22, 65mm f/5.2-27, 75mm f/6.2-32 and 90mm at 6.9-3.8. It has a minimum focus distance of 1.0 m. The shutter is electronically controlled with speeds of 2 sec to 1/700 of a sec. A electronic self-timer is available with a delay of 10 seconds.
The zooming 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. It has a adjustable diopter from -3 to +1.
The exposure system is a center-weighted system using a silicon photo diode. It has a range of 3 to 19 EV (ISO 100). The meter settings supports film speeds of 25 to 1600 ISO in 1/3 increments. Exposure compensation is available and can be changed from ± 3 EV in 1/3; increments. Exposure modes can be changed with the dial on the top shoulder of the camera. Exposure modes include (P) programmed auto, (A) aperture priority, (AS) aperture slow synchro mode and (M) manual exposure mode. Also on this dial is ISO; use the up and down dial on the shoulder to change a majority of settings. In (A) mode, the up down dial changes the aperture, in (M) mode pressing the exposure compensation button while rotating the up and down button changes the shutter settings. The settings are view able on the LCD screen on the camera back. A film tab reminder holder is also on the back. Exposure and date time information can be imprinted on the film outside the photo area. There is a handy built-in pop-up flash with a GN of 12 (ISO 100). A hot shoe is also available to attach an external flash strobe. A PC sync cord can also be used.
The GA645zi 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. A pressure plate is on the back to select between the two formats. Properly setting this plate is essential for 220 film. If improperly set, non bar code 220 film will automatically wind after the 16th exposure. Mid-roll rewind is possible with a button on the base of the camera. The camera is powered by 2x CR123A batteries.
