Hi All, I just was given a mint Minolta Maxxum 7000i, 3200i flash, remote shutter release cable,35-105 and 70-210 Minolta AF lenses and all of the user manuals as well as a Tiffen haze filter for each lens and a Tiffen circular polarizer filter. My father in law bought this system new and said he ran probably five rolls of film through it. Other than the whitish residue on the rubber part of the built in grip on the body, this entire system looks brand new. Can anyone tell me about this system? How to clean the residue off the grip? Can I still get a battery for it? I know nothing about Minolta Cameras. I have a Nikon EM, Nikon D300 and Leica M8. Thanks!
