Hi- Looking to trade my Mamiya 645 AF and Hasselblad 500cm for your Mamiya 6, 7, or 7II. Hasselblad 500cm has 80mm Zeiss Planar, A24 back, and waist level finder. It is the 50th anniversary (1991) model. Lens is free of any fungus or abnormalities. Does have some paint rub on the lens markings (very slight), and a small amount of 'pitting' on the chrome. Not really worth mentioning, but want to be as upfront as possible. Functions perfectly. Mamiya 645AF comes with 80mm 2.8 lens, and film back. Looks great and functions perfectly. I have an extra film back for the Mamiya that I'll throw in, but i never used it, so i cannot vouch for its performance. I would trade both of these for your Mamiya 6, 7 with lens(es). Additionally, I might be willing to pay for both of our shipping, if it is not an astronomical amount. Please let me know if you have any questions I can answer- thanks!
