Nikon 2.1cm f/4 NIKKOR-0 ultra-wide lens in very nice condition. Glass & coatings clean, less-than-average use marks, tight action.

Designed for use with Nikon SLRs & DSLRs with mirror lock-up (mandatory)

Includes case, finder, caps, & a generic replacement shade.

Note - Finder clips on base of rear cap broken - cap protects lens but can no longer carry finder

Makes a nice match for a vintage Nikon F or Nikkormat
