This near-mint condition Nikon Micro-Nikkor 55mm f/2.8 Ai-S macro lens comes with its rear cap. The only thing holding it back from being mint are a few dust particles inside of it and a couple of extremely light scuff marks on the barrel's exterior. Its focus and aperture are both very smooth and its glass is excellent with no fungus, haze, or separation to its elements. There is no oil on its aperture blades.
