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. All the M645 models covered here share the same accessories (finders, screens, lenses, grips and inserts). The lenses and inserts (but not the viewfinders) can also be attached on later manual-focus cameras such as the M645 Super.
M645
The original M645 appeared in 1975. It has 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 is a 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 which has a lockable collar. 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 available marked in green for full seconds 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 8 sec and 500. Set to this position to use the metered prism finders shutter speed dial.
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. 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 a it will pop-up. It takes PX28 or 4LR44 type batteries.
M645 1000S
The M645 1000S (1976) adds the 1/1000 top speed, a selftimer, a depth of field preview button and other details.
M645J
The M645 J (1979) is like the original model with shutter speeds from 1s to 1/500 but with the mirror lockup feature removed. The J is for Junior. It also lacks the upper shutter-release button of the other M645 models. It was only made for export.
