Canon Digital IXUS 55 SD450 Review

Imaging-Resource review the new Canon Digital IXUS 55 / Powershot SD450 - it features a 2.5" screen, a 3x optical zoom lens and a 5 megapixel sensor:

"The Canon SD450 features a 3x, 5.8-17.4mm zoom lens, equivalent to a 35-105mm zoom on a 35mm camera. Aperture is automatically controlled, but the maximum setting ranges from f/2.8 at full wide angle to f/4.9 at full telephoto. A maximum 4x digital zoom option increases the SD450's zoom capability to 12x, but keep in mind that digital zoom decreases the overall image quality, because it simply crops out and enlarges the center pixels of the CCD's image. Image details are thus likely to be softer when using digital zoom. Focus ranges from 1.0 feet (30 centimeters) to infinity in normal AF mode, and from 1.2 inches to 1.6 feet (3 to 50 centimeters) in Macro mode."
