I just picked up a Pentax ME Super. I mostly shoot Minoltas, but I thought I'd branch out a bit. Seems like a nice camera, but I can't seem to get the shutter to fire. This is the situation: I have fresh batteries in the battery compartment, and the light meter lights up, and displays correctly in both auto and manual modes. But the film advance lever does not advance, and the shutter does not fire. I have tried this in A, M, 125x, and B modes, and nothing happens. Is there something I'm missing here? Some setting that I need to unlock, or is this camera just DOA? (Not a huge tragedy, since I only paid $10 for it and the glass is from my K1000, but still...) Thanks in advance.
