Hmm, F1, F1n, F1N, so which one is the 84 Olympics model I just acquired? Are there different models of the 17mm lens that came attached to it? Bill Barber
'84 Olympics I would assume is the New F-1, because it was already in production for a couple of years by then, though there was an Olympics model of the F-1n as well, but must have been 1980. If the rewind knob is on top and there is a battery door on the front, then you've got a New F-1. If there is a self-timer/stop down lever on the face of the camera, then it would be an F-1n.
