i have here a very nice Zeiss Biogon 35mm with the T coating. It will fit the earlier Contax ii and iii cameras, and I believe the Kiev as well. It will not fit the iia or iiia cameras. This lens does not have fungus, haze, or scratches. Focus is smooth. Aperture works correctly. No oil on blades. This is a vintage lens. There is some very minor cleaning marks on the outer surfaces. There are some dust particles inside. I would rate it as excellent. I will give 15days to accept returns for any reason, but I do not pay return shipping. $300 plus shipping. Thank you.
