The file '2×3 Lens Board For Kodak Zoom Ektanar C 102-152mm F/3.5 3D Printer Model' is (stl) file type, size is 4.1KB.
This is a lens board for my Miniature Speed Graphic to fit a Kodak Zoom Ektanar C 102-152mm f/3.5 designed to fit a Kodak slide projector. The lens has been modified by cutting off around an inch of the rear of the barrel. It does not reach infinity in this configuration but works well as a close-up lens. The lens simply friction fits into the lens board. This design theoretically fits other Kodak slide projector lens of the same rack and pinion design but this is untested.
The test shots were on Instax Mini (ISO 800) and a fixed f/3.5 and were:
HO Scale Trains: 1/40
Sony AVC-3400 Portapak Camera: 1/60
I think my exposure or lighting was off or maybe it is just Instax Mini being temperamental.
