Features: The lens mount adapter allows Minolta MD mount manual focus lenses to be used with Nikon AI F mount cameras. It is compatible with Nikon DSLR cameras. Aperture-priority metering works on most cameras, though manual exposure compensation may be required on some models. This is a 1:1 mechanical adapter; however, the optical elements do not provide exact 1:1 magnification. Includes a corrective lens that enables focusing to infinity.
