Powered by Nikon proprietary Phase Fresnel (PF) technology, This 9.2 inch, 3.2 pound powerhouse frees you to shoot wildlife, sports and action with unmatched mobility. Pack light, move fast and catch the shots others might miss. When photographing birds, wildlife, sports or action, mobility can make the difference between nailing the shot or missing it altogether.
