Hi there,
I signed up for APUG so I can respond to your post as I am in the market for the 80mm lens. I am looking for a Contax 645 primarily for use in "special" occasions. Im not a pro by any means but am looking to get a medium format setup as a lot of memorable moments are in the near future (family weddings, babyshowers, etc). I don't have either lens you are looking for because I don't shoot MF at the moment, but am wondering if you are interested to simply sell the lens. Im located in Los Angeles, California. Please let me know
