Nikon Nikkor 50mm f/1.4 Pre-Ai - Nikon F Mount

The Nikkor 50mm f/1.4 Pre-Ai is a vintage standard lens dating from the late 1960s to the early 1970s. Known for its solid metal construction and scalloped 'diamond' focus ring, it offers a distinct vintage aesthetic. As a Pre-Ai (Non-Ai) lens, it features the original Nikon F-mount coupling prong. It is important to note that this lens will physically damage the aperture indexing tab on many modern Nikon DSLRs unless it has been professionally converted to Ai. When sourcing a Pre-Ai model, focus on the smoothness of the manual focus helical, which can become stiff over decades as the original grease dries out. The aperture blades should be snappy and dry. SDS performs a visual check for 'balsam separation' in the rear elements, a common trait in optics of this age. Verify the mount type before attempting to use it on a digital body to avoid mechanical interference.
