I'm trying to determine the serial batches. The lined presentation box includes a special 50th Anniversary neck strap. It is not the regular Nikon SLR style, but a reversion to the type style used on the Nikon One. This change also means that a standard F5 prism can not be used to replace a damaged F5 Anniversary prism. Likewise notice the special color body cap.
Top plates are titanium.
Shown is the white outer shipping box. Note the return of the Nippon Kogaku logo on the back of the camera. Unfortunately a special serial number, such as 50-0001 was not used. My thanks to Mr. Koichi Nimura, who originally brought the F5 Anniversary to my attention, months before Nikon USA admitted it existed. My thanks to Kazuo Koga for solving the mystery of the two production runs.
