Review based on a production Canon Digital IXUS 850 IS (SD800 IS)

The SD800 IS (IXUS 850 IS), announced just before Photokina 2006 back in September, is a sister model to the popular SD 700 IS (IXUS 800 IS), one of the better ultra compact models launched last year. As well as an extra million pixels or so, the new model has one very welcome new feature; a 28-105mm (equiv.) zoom lens, making it one of the few cameras in this sector of the market with true wideangle capabilities. Other changes include an ISO 1600 option, DIGIC III processor (complete with face detection focus mode) and a better screen. We liked the SD 700 IS a great deal, and on paper the SD 800 IS looks like another winner. So let's find out if it can deliver the goods, starting as ever with the headline specification:

• 7.1 Megapixels and 3.8x zoom
• Wide angle 28mm lens with Optical Image Stabilizer
• DIGIC III with Advanced Noise Reduction and Face Detection AF/AE
• Safety Zoom for extra telephoto reach
• ISO 1600
• High resolution 2.5" LCD
• 17 shooting modes including VGA movies (30 fps) with sound
• Range of optional accessories including Underwater Case
