The Coolpix P5100 is the latest in Nikon’s "Performance Series" with 12.1 megapixels, full manual controls, and perks like a hot shoe and conversion lens compatibility. The P5100 follows the P5000 with the same 2.5-inch LCD screen and 3.5x optical zoom lens, but more resolution. The $399 Nikon Coolpix P5100 is designed to be the compact camera for DSLR owners who don’t want to haul their chunky cameras to casual occasions.
