Digicamreview has recently posted a review on Pentax Optio S6, a 6.0 Megapixel point-and-shoot digital camera with 3x optical zoom lens and 2.5″ LCD Screen.
“Noise is acceptable upto ISO200. At ISO400 noise is clearly visible, and this setting should be avoided – beware of the auto mode choosing this in dark conditions. The Candlelight mode is best avoided as well, but could be used for acceptable 6×4 prints when you didn’t want to use the flash. The best results are achieved by sticking with the lowest ISO settings, such as ISO64 and ISO100.”
