Available in black or bright purple models, the Pentax Optio WG-1 ($350) is a rugged outdoor camera that can withstand 5-foot drops, 220 pounds of weight and underwater submersion to 33 feet. I found that the 14-megapixel camera, which measures 4.5 by 2.3 by 1.1 in. and weighs 5 oz., took surprisingly clear pictures for a pocket camera.
The Optio WG-1 also offers a bevy of picture-taking options. For example, you can adjust colors for underwater photos; shoot optimally for candlelight, fireworks or other tricky lighting situations; and record 720p high-def video. My favorite feature was the smile detector. The camera waits to see a smile and then shows an indicator that you can snap the photo.
A higher-end version, the Optio WG-1 GPS ($400), adds GPS and geo-tagging functionality; it's available in gray or neon green.
