I am selling a rare Shanghai 50mm F3.5 Collapsible lens for Leica thread mount. The lens is in very good condition except for what seems to be some faint thin fiberous lines around the rim of some internal element. I don't think this will impact images significantly (but everyone has their own opinion about glass!). The iris blades are clean and the mechanical motions normal. The cosmetic condition is very good. This lens is nicely machined and constructed, much more so than similar Elmar copies made in the former Soviet Union - nice metal work! Makes a really fine collectible that can be used as well. Price: $225 plus insured shipping I can take personal checks, money orders, bank checks, or PayPal.
