The Nikon F-mount lens legacy NIKON is one of the few camera manufacturers to offer mount compatibility with its lenses going back to its first SLR cameras in the late 1950s. Photographers have bought into the Nikon F-mount lens system because of its compatibility with legacy lenses. Professionals, enthusiast, and amateur photographers have enjoyed the great optics, handling characteristics, and unique image “signature” of Nikkor lenses for over six decades.

While Nikon has retained the F-mount into the digital era, the company has tiered their camera bodies in part by limiting interoperability among camera, metering system, and lens. As a result, Nikon users of cameras like the D3xxx and D5xxx,  and others lacking mechanical F-stop coupling, cannot fully enjoy legacy F-mount manual focus lenses with a Nikon DSLR. Nikon increasingly has made manual focus lens compatibility a feature of the prosumer and professional level bodies only, such as the D300/7000 and D1-D4. But even with a pro level body, each manual lens must first be programed into the non-CPU lens database and then selected each time it is used. Despite this clumsy work-around to accommodate classic Nikkors, there are limitations with exposure modes and the need to manually coordinate lens choice with the database.
