I just bought a used N80 via eBay. The camera arrived today, and it seems to be in a great shape, except that there's a strange, see-through "gap" beneath the bottom of the viewfinder where the aperture and shutter speeds are displayed. Here's a couple of pictures of the viewfinder: I've looked inside the mirror chamber of the camera, but can't see anything obviously wrong. The camera seems to work OK with a lens attached. I haven't shot a roll through yet, I'm going to do that later today and see how they turn out. In the meantime, does anyone know what the abnormal showing above may be?
