I'm selling a 135mm F4 Elmar-M lens, with attached tripod mount, in very nice user condition. The glass is free from scratches and cleaning marks. There are some dust particles trapped inside, along with one small fleck of something (dust, flake?) that's perhaps one mm. No caps, but there's a Leitz hood that also fits 90mm lenses, and the Leica leather case, both in good shape. I don't know much about this lens--it came with an M3 kit I bought. Price is $200 net to me (after PayPal and postage).
