Hey, I'm new to medium format photography but have been looking around to buy a Hasselblad. I'm pretty good at knowing prices for 35mm film camera's but I haven't a clue about medium format film camera's. So I recently saw an add for a Hasselblad 500C/M. The guy send me a snapshot of it, but can't tell me too much about it since he is no expert. So it's a 500C/M with the waist-level viewfinder and (I think) a NC3 prism viewfinder based on the shape and the Hasselblad logo. There are three film backs. It has a 100mm F3.5 lens with a rectangular hood. Looks like a C lens with ribbed focus ring. It comes with a neck strap and a case. Since I've got no idea what a set like this would be worth, I would like to ask you before I make a bid. Thanks!
