Light & compact camera body, replaces Mamiya Press bodies + M-mount. See the diagram in the gallery for the compatible backs. Not on there is the Model 3 back that goes great with this body. Takes all Mamiya Press, Super 23, Universal Press compatible lenses.
The assembly is 3 pieces, consisting of Body + top mounting lip + sliding back lock bar. A 2-piece body is also available (advised only for materials with strong layer fusion), consisting of Body + sliding back lock bar. Download the grip cable release clip in my designs.
Lens mount is designed for a tight enough fit on most lenses, and doesn’t always require a set screw. Use (1) M2x8 knurled hex screw & M2 nut as needed for the set screw.
Back lock requires (2) M3 knurled screws & (2) M3 nuts, M3x16 is ideal. Top lip requires (3) M2x16 countersunk screws & (3) M2 nuts. Upon test fitment of your completed assembly, leave the (3) M2 screws for the top lip slightly loose and adjust based on how much pressure is put on that lip.
“B” version incorporates the top lip, eliminating the need for the M2 screws, and is only recommended for Carbon PC, NylonX, or similar materials.
I designed this for Priline CFPC, which has different shrinkage than other materials. Included is a test print file for the back that will let you see what changes need to be made to fit your body. Lens infinity focus may also be an issue, but the body has resting pads that can be sanded down or removed as necessary. To go in the other direction just add felt tape on top.
Ideal distance from the first lip of the lens mount (where the lens tabs rest), to the film back's pressure plate should be 61.35mm, no more than 61.5mm, and no less than 61.25mm.
