I think that the Nikon F2 was the best SLR camera until 1996 when Nikon produced the F5*
The F2 is the successor to the Nikon F, their first SLR camera, released in 1970. The F2 featured many revisions of the inner and outer workings of their SLR template. The black one above is a Photomic F2 which means it came with a light meter built into the removable viewfinder. The Nikon F system was a modular design system catering to professional photographers. You can remove or swap out the back cover, viewfinder, eye piece, focussing screen and the lens of course. Each of the removable parts had a wide range of replacements which were designed for specific applications such as high volume film backs and photometric grid focus screens. Its really weird seeing your camera stripped down to just a mirror and a shutter.
