Nikon 50mm f1.4 Nikkor K Pre-AI - Lens

Manual focus normal lens made for F-mount SLR cameras by Nikon starting in 1974. These K-type lenses are from the transition from Pre-AI to AI lens designs and feature elements of both. Two 50mm f1.4 K lenses were made, one with the same optical formula of previous Pre-AI lenses in a new housing and one with the modernized AI optical formula. The second version is different externally as well. The letter K does not appear anywhere on either lens. Metal and plastic body available in black.
