As with the rest of the Stylus line, the Olympus 720 SW design is based around a weatherproof body that ensures wherever you go, your camera will go right along with you, unhindered by rain, sleet, or snow that would see most digicams left at home or in a sealed case, unable to get that chance-of-a-lifetime photo. The "SW" in the model name hints at two more unusual features though: the 720 SW is shock-proof to the MIL-STD-810F standard (which means it can withstand a drop from 5 feet), and it's waterproof to a depth of three meters.
