Underwater Camera Shootout

If you're heading to the beach this winter, you might want to pack the Pentax Optio W20 or the Olympus Stylus 720SW in your beach bag to capture your underwater adventures.

If your upcoming travel plans include a tropical escape aboard a cruise ship or whiling away an afternoon on an azure beach on some speck of land in the Caribbean, you're in luck. Not just because you're going to be working on your tan while everyone else is bundled up for winter, but because Pentax and Olympus have now put underwater digital photography within everyone's reach.

With competing 7-megapixel 3x zoom compact digicams that can handle a snorkeling adventure right out of the box without any additional housings, you might want to consider packing either the Pentax Optio W20 or Olympus Stylus 720SW in your beach bag to capture your underwater adventures.

There's nothing on either camera that jumps right out and says "we're waterproof" in a dramatic manner, but if you look close, certain design elements -- such as locking battery compartments and rubberized control buttons -- hint at the secret life of these cameras.

The 7.1MP 3x zoom (38-114mm equivalent) Stylus 720SW ($300, street) is Olympus's first dive into the underwater realm. With a compact, shockproof build that's submersible up to 10 feet, the 720SW doubles the depth rating of Pentax's 4th generation aquacam, the  7.0MP 3x zoom (38-114mm equivalent) Pentax Optio W20 ($250, street), which upgrades circuitry, processing and megapixels of its predecessor, the 6MP W10.

So does the deeper-diving Olympus upstart have what it takes to unseat the Pentax Optio W20 as the king of the seas?
