Some new lower-end A series cameras tonight as well, including the PowerShot A590 IS (8 megapixel sensor, 4x zoom with image stabilization, optional optical converter lenses), PowerShot A580 (8 megapixel sensor, 4x zoom, but no stabilization here -- it's got an "easy to hold grip), and the PowerShot A470 (7.1 megapixel sensor, 3.4x zoom, f/2.0 wide-angle aperture. All feature facial recognition, motion detection, high ISO, 2.5-inch LCDs, auto red-eye correction, DICI III processors, and affordable prices ($180, $150, and $130, respectively).
