Was going to use this for a pinhole camera and has been sitting around since. One would make a plate to mount the pinhole on and sandwich in between the adapter and the lenshood. I'll even include the 600 micron pinhole I was going to use.
I can't remember what i paid for it, I only remember that it took awhile for it to come up on ebay. Lets say $30 or so plus shipping. I'm also looking for darkroom stuff. 5x7 paper trays, 4x5 contact printing frame, small safelight, etc.
