I have a problem with my Nikon N75 i was hoping someone could help me with. It seems like the zoom is jammed. I can't turn the lens zoom in or out. It's locked in at 80mm. The camera did fall off of a nightstand onto the carpet about 2 feet, so i'm worried it has something to do with this. But its possible i pressed something to lock the zoom and i just don't know what i did. It's a relatively new camera. Could someone help me? I'm not quite sure what to do. Thanks so much!
