Pentax Optio 330RS review
I went into the store with intentions to buy a Canon S200 (I had borrowed one for a week and liked the small pocketable size and image quality) but got sidetracked into buying an Optio 330RS because it was the same size as the S200 with more features and a 3x zoom (versus the 2x zoom on the S200). I had the Optio for a day and took it back and bought the S200. The Optio image quality was just not on par with the S200, too much noise, etc.
Image quality is poor, too much noise. General performance is also slow such as zooming and panning captured images compared to the Canon S200.
