This Nikon Nikkor-S Auto 5cm f2 (Pre-AI) is in excellent condition with only minor cosmetic wear. This lens is an early 7 element/5 group design, with later six-bladed diaphragm. Distance scale exclusively in feet. Smooth focus and glass is great for its age with only moderate dust. Aperture blades show a bit of staining but are snappy. Both a unique historical piece and a great everyday user.
