Panasonic's Lumix line got further upgrades Tuesday with two new rugged cameras. The TS4 is its new, toughest camera and can withstand water depths of up to 40 feet, drops of up to 6.6 feet, most dust, and temperatures down to 14F. Like some of the newest rugged cameras, it has an altimeter and a barometer log, although it now has the new GPS system of the ZS20 to load map data from a DVD for advanced geotagging.
