Nikon CPU lenses on your DSLR Nikon camera. Enjoy all metering and exposure modes and full EXIF data using classic manual focus lenses.
Are you a Nikon digital SLR user who wants access to the millions of manual focus Nikkor lenses? Frustrated by the difficulties getting your camera to work properly with manual lenses? Tired of limited functionality, no metering, or having to rely on the cumbersome manual lens database? Read on!
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 D40, D60, D90, D3100, D5100, and others, cannot fully enjoy legacy F-mount manual focus lenses with the convenience of digital imaging. Nikon increasingly has made manual focus lens compatibility a feature of the professional level bodies only, such as the D1-D3, and more recently D300 and D7000 series cameras. 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 work-around to accommodate classic Nikkors, there are limitations with exposure modes and the need to manually coordinate lens choice with the database.
