For those who like to backpack, hike or camp, the least you want to worry about is damaging your digital camera. The Pentax Optio WS80 ($250) features a waterproof and dust proof construction for taking photographs under water or in less than optimum shooting conditions. This point-and-shoot camera can withstand depths up to 5 feet and features a 10-megapixel sensor, 5x internal optical zoom and a large 2.7-inch LCD display. The Optio WS80 is also capable of capturing HD video in 720p at 30fps, face detection and image stabilization.
