The Nikon 105mm f4 AI-S Micro-Nikkor is a manual focus macro lens for the Nikon F mount. Cosmetic condition is fair, with some surface wear. Diaphragm blades move well, glass is clean, with some dust. Not the most pristine Micro-Nikkor you’ll ever see, but it’s in good working order. Provides 1:2 magnification without the use of extension tubes.
