Canon introduces three PowerShot compacts that come with the image stabilization feature. The SD770 IS, SD790 IS, and SD890 IS all shoot at 10 megapixels with an optical stabilization to produce clear shots.
The three model differences are separated by design and lenses rather than megapixel count. The SD770 IS is considered the starter with a standard 3X lens but is also the thinnest-ever IS camera. It can produce up to 300 shots on a full battery charge. It shoots at up to ISO 1600 sensitivity with a 2.5-inch LCD and optical viewfinder.
Moving to the higher-end SD790 IS primarily swaps out the optical preview in favor of a larger 3-inch LCD as well as a new-look set of rear controls that render the back almost entirely flat.
At the top end, the SD890 IS adds a 5X zoom lens and restores the optical viewfinder in exchange for a smaller 2.5-inch LCD.
