E-330 DSLR today, Olympus also announced an overhaul of its popular Stylus line (known as mju outside of the US). The Stylus 710 is a lightweight compact with a 7.1 megapixel imager, 3x optical zoom, 2.5-inch LCD, and -- at least according to Olympus -- the ability to take sharp, flash-free pictures under low light at speeds as high as ISO 2500. The Stylus 710 is expected to sell for about $349. The Stylus 720SW (above, left) matches the 710's features, and adds a raft of its own, including image stabilization, a ruggedized casing that Olympus says can withstand 5-foot drops, and a waterproof housing that allows underwater shooting in depths of up to 10 feet. Pricing is estimated at $399. Finally, the Stylus 810 (above, right) bumps the sensor up to 8 megapixels, and the ISO up to 3200, and includes image stabilization, VGA movie mode and a weatherproof (but not waterproof) housing, for an expected price of about $429. All models are expected to be available in February.
