Cameras are not only getting smaller, they're getting tougher, with manufacturers producing ruggedized and airtight-to-dust versions for adventurers and klutzes alike. When it comes to the design of the external housings, different companies use different techniques to achieve the required protection.

Panasonic's Lumix TS1 (waterproof to about 10 feet and will withstand drops from nearly five feet) recesses the glass and buttons to keep them out of harm's way.

Canon's funky-looking D10 (waterproof to 33 feet, freezeproof down to 14 degrees Fahrenheit and will survive a four-foot drop) hacks the corners off completely, spreading out the potential points of impact.

Olympus' Stylus Tough 8000 and 1030SW (waterproof to 33 feet, freezeproof down to 14 degrees Fahrenheit, will survive a 6.6-foot drop, and crushproof up to 220 pounds) are embedded within a metal casing.

Photography reviews point out that all of these cameras take crappier photos than their wimpy non-tough counterparts, but in situations where no regular camera would last, crappier photos are better than no photos at all.
