You see them all the time at sporting events: long-range lenses the size of an artillery shell with a little camera bolted on the back. And in the hands of many spectators, you see smaller versions of the same thing: compact digital cameras with great big lenses.
I’ve been trying out one of the latest, the Coolpix P520 from Nikon Corp. It’s a limited but decent camera that’s most noteworthy for a big-time lens with 42X optical zoom that will deliver high-quality images of people and objects a block away. This $430 camera also shoots very good high-definition video, made even more impressive by excellent audio recording that gives movies a surround-sound feel. With its built-in GPS for geotagging your photos and an optional $60 Wi-Fi transmitter, the Coolpix P520 is a major step up from the average point-and-shoot.
