This near mint condition Nikon UW-Nikkor 20mm f/2.8 underwater wide-angle lens comes with both caps, instructions and in its original box. It is for use with Nikonos cameras. The only thing holding it back from being mint are a couple of light scuff marks on its mount. Its focus and aperture adjustments are both smooth and its glass is free of nay fungus, haze or separation to its elements.
