I have a Carl Zeiss 100mm f2.0 planar in Contax (c/y) mount. It is the mm version. The glass is perfect, no cleaning marks, scratches, haze, seperation, fungus, etc. The body is in excellent condition with very few microscopic marks. The metal hood has seen better days, but has no dents. here is a good review on the lens:http://www.pebbleplace.com/Personal/Contax_100mm_Planar.html It is definitely the sharpest telephoto I've ever owned and the bokeh is amazing. It focuses really close so there's almost no need for an extension ring. I can't find one on eBay for under $1000 and I've seen these sell on Fred Miranda (some without the hood) for ~$950. Asking $850 OBO Would consider trades on a Leica 35mm RF body (m2, m4, m5 or m6) or Leica 35mm lens. Partial or full trade will depend on many factors.
