Nikon 200mm f4 micro Ai-S , fair used condition, barrel has some wears, nothing major. Front lens element has kind of oil like surrounding the outer side front lens ,hard to take a picture of it,see last pic, doesn't affect picture quality. No caps, will pack securely. Aperture ring and focusing ring works great and smooth, built in hood retracted smoothly. Perfectly usable. Compact dimension for 200mm micro, sharp result as well. last pic is sample pic took from this lens.
