I work at a camera store, and an older gentleman brought in a mamiya 645 1000s. At first i looked all right, but then i noticed it had fungus or something growing in the lens, and the shutter has mold on it as well. The lens focus but its a little snug, but not too bad. The shutter appears to fire correctly (though i haven't had it professionally tested) I shot a test roll at my work and it seems to work well, though since i was inside i shot everythign at 2.8 and i assume that at 11 or 16 the fungus will start to make a difference. Since it needs a lot of work the older guy wanted to see if it was worth fixing for him, and its a lot of work he just gave the camera to me. I remember reading of some way of killing the fungus or whatever it is without taking the lens apart. And I'm sure its a silly question, but how difficult is it to take the camera apart and clean it? (i've taken alot of things apart, but never a camera)
PS: I know your all going to tell me not to attempt it, but I just needed to hear it from you all Grazie!
