Nikon Nikkor-S.C 50mm F1.4 Lens for Rangefinder S Mount -Read-
What is a Nikkor-S.C? Back in the day Nikon had a system of letters for different numbers of elements in the lens. "S" is short for "Sept." which indicates seven elements. "C" indicates that it is the later version with multicoating. This is the best version of this classic lens.
This one is in good condition with moderate wear. There are a few small cleaning marks on the front element and a light amount of dust inside, but it will not affect your image quality.
