I have a broken Yashica Auto Yashinon DS-M 50mm 1:1.7 lens. Neither focus nor aperture work. I would like to take the lens apart to use the glass for a diy project, but I can't get into the thing! I have removed the three tiny screws next to the aperture ring, but that doesn't seem to have done anything.
Does anyone know of any manuals or resources for this lens?
