Thread: Need Help Identifying Obsucre Cinema Mount

    Need Help Identifying Obsucre Cinema Mount

    So I just picked up these two obscure lenses on eBay. One is an Elgeet Cine Navitar 35mm f/2.0 and the other an Elgeet Cine Navitar 8mm f/1.5. From what I could deduce they were made for Fairchild high-speed 16mm cameras, but information on those cameras is scant (all I could find: ). The registration (mount to sensor) distance is somewhere in the 36mm area, and the mount's diameter is 35mm minus the flanges. There are 3 flanges and each is notched kind of like an Arri PL mount.

    I checked through these two lists of cinema and other lens mounts and the numbers and design don't quite match anything out there:

    I really hope this isn't a mount unique to those Fairchild cameras because I'd have to fashion some sort of adapter myself. Anyone have any ideas? Pictures:

    Try to see if there is another mount under the Fairchild one?

    Do this on a flat surface with news paper etc underneath to catch anything that falls out, just in case! Unscrew the odd mount and see if there is a C=mount there?

    Thanks. With that recessed screw removed the flange mount and wide ring screwed right off. No errant parts fell out and the rest of the lens appears intact. Now I've got a 30mm thread (so non-C-mount) to work with. I've got a M42-m4/3 focusing helicoid on the way from Hong Kong. Now I just need to figure out how to adapt 30mm to 42mm, and since they don't make filter step down rings at those measurements....

    Anyone have any recommendations for a machine shop that takes mail orders for camera-related work?
