“The move to more megapixels has compromised the overall image quality at higher ISO speeds, limiting this camera’s ability in low-light environments.”
PhotographyBLOG has posted their review of the Canon PowerShot SX20 IS [Specs], a compact ultra zoom digital camera that "remains a likeable and easy-to-use camera" with its 12.1MP resolution (1/2.3-in. CCD), 20x wide-angle optical zoom (28-560mm equiv.), optical image stabilization, 2.5-in. LCD (230K dots), PASM modes, Smart AUTO, Scene Modes, and HD movie (1280×720) @ 30fps.
