Help the movie camera! Pretty Please!?
Therefore, I have an old Nikon N70 (film) camera has been working hard during the time I had, until recently. Suddenly I got an error on the LCD screen with a flashing empty battery. Assuming that the rule will replace the batteries. However, despite the fact that the batteries are new and fresh I'm still getting the infamous "err" empty battery and LCD screen and refuses to close the shutter. Any ideas?
ERR is the message that the camera is not set and locked to its smallest aperture, f/16 f/22 that the film oo is properly installed.
