As if introducing a 10.2-megapixel SLR wasn't enough, Pentax has also announced its newest Optio point-and-shoot, the Optio T20. The 7-megapixel ultracompact boasts a 3-inch touch screen LCD, a 3X optical zoom lens, and 12 shooting modes. At 0.77 inch thick, the camera is set to compete against the ever-growing bounty of extremely thin, pocketable cameras that have been saturating the market for the last couple of years. The T20 has 12MB of built-in memory, though most folks will want to take advantage of the SD card slot if they're planning to shoot more than just a few images. Pentax expects the T20 to hit stores in October for about $350.
