Lens Serial # 1113726
Condition:
Pictured Camera is sold As Is, lack of battery and film limit my ability to test it's functionality but the camera appears to overall be in Average shape.
- The black finish of the rubbing off along the metal frame in quite a few places and there is a bit of residue in some spots from where there were once stickers.
- The Film case is a bit tricky to open (see below), but it does open and close properly.
- Someone has scratched the following on the inside of the Film case door just under the hinge: JK 11/5/87 1
- Adjusting the F-stop on the lens opens and closes the lens aperture
- The switches, dials and buttons all move and click nicely but without film I can't confirm their functionality.
- Since it can't advance because there is no film in the camera, the mirror is up, which prevents seeing anything through the viewfinder.
- The Lens appears clear and to have a working manual focus, but without looking through the viewfinder it's hard to be certain.
About the Camera (According to Camera Wiki)
The Mamiya M645 is the first series of 4.5×6 SLRs made by Mamiya. It features an electronic focal plane shutter. The finder and screens are interchangeable, but there is no magazine back, only pre-loadable film inserts. This made it easy to preload onto less expensive film magazines, but no mid-roll change is permitted. Up to 15 frames can be captured onto a 120 roll film.
The original M645 appeared in 1975. It has a knob advance with a flip out crank and shutter speeds from 8s to 1/500. It sports a mirror lockup and double exposure lever. There are dedicated flash sync terminals on the body. One for electronic X and the other for bulb FP. Flash sync is 1/60 sec. There are two shutter release buttons on the camera body. Both are useful depending on type of grips and viewfinders used in the system. The first one is on the front below the lens mount. It has a lockable collar and is threaded to accept a cable release. The second is on a small ledge on top of the camera to the right of the viewfinder. The shutter knob is on the left hand side of the body. The speeds marked in green are for full seconds they include 1, 2, 4 and 8 sec. For slower shutter speeds in hundredth of a second they are marked in orange 2, 4, 8, 15 of a sec. In white, 30, 125, 250, 500 of a sec. 60X shutter speed is in red and represents the maximum speed for electronic flash sync. There is also a circle marked in red between B and 500. Set to this position to use the shutter speed dial on the prism finder; the film-speed dial is incorporated in the finder's shutter-speed dial. The camera body has lugs instead of slots for the strap mount.
The film back has a memo clip to attach a roll film box top as a reminder of film type. Opening the film door requires pressing on to this memo area, while moving the lever to the right. Loading film onto inserts require aligning the paper leader start mark with an indicator on the insert. There are two inserts available, one for 120 film the other for 220. The number of exposures on the film counter is affected by they type of insert used. The counter is reset when the insert is removed from the film chamber.
The M645 takes a 6 volt battery that provides power for the camera body as well as finders. It can be accessed at the base of the camera body by the tripod socket. To use twist the knob on the plate in the direction indicated and it will pop-up. It takes PX28 or 4LR44 type batteries. The location of the battery compartment is not the best. Grips and or tripods plates can block access to the battery. There is also a red battery test button by the top shutter release. By pressing it, a lamp on the shutter knob side will light.
The lenses have rings for focus and aperture, along with focus and depth of field scales. There is one switch changeable from A to M by the lens barrel. This changes the lens from automatic to manual for stopping down the lens to the aperture selected for depth of field preview. The lens has a metal yoke at the mount end; the signal pin of the metering prism (if used) must engage with this yoke as the lens is mounted. Its position signals to the meter what aperture is set.
