A relative came across a Polaroid 103 a few weeks ago; not knowing what to do with it, I inherited it. However, after doing a few test snaps with Fuji FP100 and a 123 battery, I find that the rangefinder doesn't seem to be calibrated properly. That is, I focus and take the picture, but each one comes out completely blurry, too much so to be caused by shaking. Any ideas as to what the problem might be? I am not much of a Polaroid user, and so don't really know what sort of things to look out for. Perhaps the film pack wasn't inserted properly/on the right plane? Thanks!
