I picked up a working Cyclop M10A Russian-made night vision scope with a Cyclop 85mm ƒ1.2 lens at a flea market for $45, hoping I could adapt the aperture-less but super fast lens. Unfortunately this earlier version has a protruding rear element that extends too far through my m32>m32 adaptor to mount. I can add m42 extension tubes, but the lens really doesn't lend itself to macro work. Removing the rear element lets me take photos w/o extension tubes but closest focus is somewhere short of infinity, but that's not super useful, either. I've not had much luck thus far Googling, anyone ever run across info on adapting these protruding versions to m43?
