DESC: The PowerShot S90 employs a 10-megapixel High Sensitivity System by combining a powerful CCD sensor and Canon’s DIGIC 4 Image Processor. Thanks to this, the S90 is dramatically more sensitive than cameras with identical megapixel counts, and delivers spectacular images with minimal noise. Increased sensitivity demands a higher ISO speed, and the PowerShot S90 delivers with a maximum setting of ISO 3,200. Blur and camera shake are notably reduced for the ultimate in sharpness and clarity.
