The Olympus Tough TG-2 iHS is a solid, all-round waterproof camera that produces images on par with regular compact cameras. Underwater photos come out without any color distortion. Video is good, and it has three panoramic options. You can use extra lenses for more varied shots. The GPS lets you track and log your photos.

The Sony Cyber-Shot DSC-TX30 is stylish as well as ultra-slim and light. It’s a basic camera, lacking both GPS and Wi-Fi, though it does have some other neat features, including iSweep Panorama. Photo quality is very good. The TX30’s touch screen is great for use on land, but impossible to use underwater, making this a great waterproof, not underwater, camera.

The Panasonic Lumix DMC-TS5 has a tough, sturdy body and an extensive feature set, including some manual controls. Its fully featured GPS has a compass, a manometer and a landmark database. Image quality is good, both on land and underwater. Wi-Fi is elaborate, with Near Field Communication. Its long battery life makes it ideal for travel.
