Capture the moment this summer with the latest waterproof digital cameras. Designed to seal out moisture, they can take a dip when you do. The Pentax Optio W30 (pentaximaging.com) can go 10 feet below the surface for up to two hours. For extreme travelers, the Olympus's Stylus 770 SW (olympusamerica.com) can endure 33-foot depths, frigid temperatures or 220 pounds of crushing pressure. Vivitar's 6-megapixel ViviCam 6200w (vivitar.com) features big buttons for easy shooting. Prefer moving pictures? Sanyo (sanyodigital.com) comes out with the first waterproof consumer camcorder, the Xacti E1, later this month. It doesn't get any wetter than that.
