Nikon DW-2 6x Focusing Finder for the Nikon F2. This finder offers a magnified viewfinder image that is vertically corrected and laterally reversed.  Great for macro work, astro, and any other application which requires the utmost focus precision. This finder is in superb cosmetic condition, and diopter adjustment is smooth.  Optics are clean. The rubber eyecup has not aged well and has a permanent deformation, but the finder is perfectly usable without it.  Comes with protective cap, original box, and foam insert.
