Can't load the film in the F80 leader won't take up

Open the camera-back. Look to the right where the take spool is there is a red mark. The leader should go to the red mark not any more. Now look at the inside of the camera-door, you should see close to the hinge a springy thingy-bob. If that is missing then when you close the door there is nothing to push on the film to seat it. On that spring is a chrome pin as well. Hope this helps you.

Previously, I was never a fan of the lower-priced Nikon SLR bodies. The F50/N50 was remarkably featureless, the F60/N60 had the nagging problem of hiding what it was doing (like switching to center-weighted metering when you pressed the exposure lock button!), the F65/N65 doesn't allow use of older AI-S lenses, and the F70/N70 featured a funky user interface and lacked depth of field preview. Virtually everywhere you looked, Nikon's inexpensive bodies lacked a key feature, didn't provide enough control, or did things automatically that you didn't necessarily want them to.
