Mamiya C-series adapter for Kiev88/Salyut prism viewfinders

thingiverse

A Mamiya TLR with TTL Spot metering! This adapter makes it easy to mount a Kiev 88/Salyut prism viewfinder onto a Mamiya TLR. The fit is secure and tight, the entire frame is visible and sharp, you get accurate TTL metering (including spot) depending on the type of prism used, and the image is significantly brighter and larger than with Mamiya's own porro-viewfinder. So far, it has been tested successfully with a Mamiya C3. Other Mamiya TLRs may also work, but I don't have any to test them with. Prisms for Hasselblad 500-series cameras might fit as well. If you've tried this adapter with other Mamiya C-series bodies, please let me know so I can add more information on compatibility. EDIT 19.7.2019: An additional version has been added which fits the Mamiya C330. The first version is recommended for the Mamiya C3. No modifications are needed to the camera body or prism. Print upside down, supports touching buildplate only. THIS ITEM HAS BEEN TESTED AND FOUND FULLY FUNCTIONAL. IT TOOK HOURS OF DESIGNING, MODIFYING, AND SEVERAL TEST PRINTS TO GET EVERYTHING RIGHT.
