The PowerShot S90 employs a newly-developed, 10.0 Megapixel High Sensitivity System by combining a powerful CCD sensor and Canon's DIGIC 4 Image Processor. Thanks to this technological advancement, 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 new maximum setting of ISO 3200. Blur and camera shake are notably reduced for the ultimate in sharpness and clarity.
In addition, a new Low Light mode lets you capture images in an astonishing range of conditions. The camera automatically adjusts the ISO speed from ISO 320 to ISO 12800 in relation to ambient brightness, subject movement and camera shake.
