Nikon mount Sigma manual focus 16mm f/2.8 fisheye multi-coated lens in excellent condition, showing just a few minor scuffs on the barrel. (see photos!) The glass looks clean with no visible haze or fungus, but a few marks/faint scratches can be seen on the front element's coating. The rings turn fine and the aperture is snappy and oil-free.The thin rubber aperture ring moves around freely so the ring needs to be hold tighter when changing aperture settings. This nice lens will fit Nikon F-mount cameras and other models with a proper adapter. Made in Japan. It comes with shade and front & rear caps. This sale is final. Shipping to approved US address or with Ebay Global. Thanks for looking!
