I'm building a box camera and I want to incorporate a focusing mount. I might be able to use the focusing parts out of a 35mm lens, so I'm looking for a <$10, possibly broken 35mm lens that I could dissect.
As I was looking for parts to fix my sink drain, I saw some 1.5in. black abs fittings that would work as a focusing mechanism. Might want to check them out.
I don't have a 35mm lens I can give you, but I do have a junk Olympus OM10 and M645Super bodies only. If you want the lens mount, I could potentially take one of them apart for you. I also have some junk enlarger lens if you want to adopt one for your project. Let me know if you are interested.
