You can cross underwater housings off the packing list for your snorkeling vacation -- Pentax's Optio W30 ($263, street) can take wet shots up to 10 feet deep without the hassle of those big, clumsy shells. The 7.1MP compact is dust-proof, too, so dropping it in sand, mud, or ice cream won't wreck it. Its 2.5-inch LCD has an antireflective coating and Bright mode so you won't have to hide under a towel to see what you're shooting. The small camera also packs a 3X optical zoom, Digital Shake Reduction, and Face Recognition autofocus. At this price, you won't get soaked.
