The Nikon F-501 is a simple and stylish camera with autofocus. Although it is an old item, it has very little signs of use and a beautiful body. After inserting test batteries, I checked the functions of each part and they are in good working order. The viewfinder is also clear. The AF focus and flash contacts have also been checked with a test strobe. The batteries used are AA batteries. - Model: F-501 - Brand: Nikon - Autofocus: Yes - Back Design: Simple design - Body Color: Black Thank you for viewing.
