This specialty point-and-shoot is pricey for an ultracompact, but it lets you take pictures in places where few other cameras can go: underwater. The Olympus Stylus 770 SW is submersible to a depth of 33 feet and will withstand temperatures as low as 14 degrees Fahrenheit. It's pretty rugged, too: The camera can be dropped from a height of 5 feet, which I confirmed in my testing, and is designed to shrug off 220 pounds of direct force.
