Hi, There aren't too many users of the Rollei 6000 system but I am posting these lenses for sale anyway: Rollei Zeiss 50mm f4.0 Distagon HFT - $300. Rollei Zeiss 80mm f2.8 Planar PQ - $200. Rollei Zeiss 250mm f5.6 Sonnar HFT - $200. Schneider-Kreuznach 180mm f2.8 Tele-Xenar PQ - $1000. 9, 17, 68mm extension tubes - $50. Pictures for the Schneider 180mm are below. I have pictures for other lenses if anyone is interested. All lenses are optically perfect with no scratches, haze, fungus or other nasties. All leaf shutters are fully operational. Shipping will be via FedEx at around $30 or so depending on your location. Thanks folks.
