The LensCoat Nikon Lens Cover (Digital Army Camo) is designed to fit a Nikon 800mm f/5.6 AIS manual focus lens. It covers the lens with a 100% closed-cell neoprene coat that protects the lens from bumps and scratches. Ideal for nature and outdoor photographers, and for sports shooters and photojournalists. It also provides a thermal barrier, protecting your hands from cold lenses in lower temperatures. The cover is waterproof, providing protection in inclement weather. The Digital Army Camo is an advanced computer generated camouflage pattern. It is modeled after the U.S. Army's standard-issue ACU pattern, which provides a pixilated pattern that maximizes visual break up. The pattern, constructed from small rectangular pixels of color, mimics naturally occurring dappled textures and rough boundaries.
