FUJIFILM FUJICA GS645 Pro Medium Format Film camera 75mm F3.4 Hood with Case The Fuji GS645 series of compact medium format cameras was released in the early 1980's. They share a nearly identical body and available with fixed lenses of various focal lengths. The GS645 and GS645S uses rangefinder type focusing while the GS645W is scale focusing.
They take 120 and 220 film using a 6 x 4.5 format and were known for very sharp lenses. The design of the cameras results in the viewfinder being in a portrait format orientation instead of the more common landscape format. They feature a leaf shutter based design using a Copal #00 shutter with speeds of 1 to 1/500 of a sec.
The shutter can be a bit sticky and inconsistent. I did some tests and sometimes it doesn’t fire. The built-in light meter is activated by pressing the shutter release button half way. The meters ISO settings are adjusted on the lens barrel, it's setting window is sandwiched between the aperture and shutter speed rings. The meter uses three LED lights +, o and -; in the viewfinder to aid in exposure. The film transport is manually operated with a single stroke film advance lever on the top plate of the camera.
Advancing the film also cocks the shutter. Surrounding the shutter release button is a release lock. A hot shoe is provided for external flash and can be synced at any shutter speed. The film counter is on the back of the top plate. These cameras are powered by 2x LR44 batteries located on the bottom base plate. A tripod mount is also provided. Meter display LED status + 1 or more over o and + 1 over o and + (half) 1/3 over o correct exposure o and - (half) 1/3 under o and - 1 under - 1 or more under The camera back contains a film box reminder holder and a 120/220 indicator. Inside the back a pressure plate to switch between 120 and 220 film.
Press and move the plate so the desired film type is indicated. When the cameras are loaded with 120 film it will produce 15 exposures, 220 will do 30 exposures and half roll 120 will produce 7 exposures. Loading the film is very easy with these cameras, with the back open; press the red spool release buttons. Remember the take up spool is located on the right, the same side as the film advance lever and the film is on the eyepiece side. Insert the spools using the top spindles and lock with the spool buttons. Draw the paper leader from the film side to the take up reel; inserting the head into the spool slot. Advance the film until the start mark on the film is lined up with the indicator on the body. The Fujica GS645 Professional was released in March 1983 and is a folding rangefinder camera utilizing a bellows for focusing.
It has a EBC Fujion S 75mm f/3.4 lens comprised of 5 elements with the closest focus distance at 1m. Aperture stops on the lens include 22, 16, 11, 8, 5.6, 4, and 3.4. To open the camera pull the lock button on the front cover, and swing it till it locks with a snap. To close make sure the lens focus ring is set to infinity and the shutter is cocked. Press the knobs on the inside of the lens cover to release the lock and swing the cover towards the body.
The light meters has a measuring range of 3.5 to 18 EV and can be set from 25 to 1600 ISO in 1/3 stops. The finder contains a coupled type double image rangefinder for focusing. A 0.63x magnification with a 39.5 mm baseline which is a 24.9 mm effective baseline. Bright lines are present with automatic parallax correction to assist in framing.
