Canon is expanding its Digital Ixus range of compact cameras with three new 10Mp models. The 10Mp Canon Digital Ixus 85 IS replaces the 70 IS - the best selling digital camera of last year.

The Digital Ixus 970 IS sits at the top of the range and is described by Canon as its "most optically advanced" digital camera. It is priced at £299. The 10Mp camera has a 5x optical zoom, 2.5in LCD screen and a multi-control dial for scrolling through menus, changing settings and reviewing images. It comes in a two-tone metallic finish.

The Canon Digital Ixus 85 IS is a direct replacement for the popular (Canon says it sold 2.8 million of them last year) Digital Ixus 70 IS.

The new model costs £239 and has a 3x optical zoom lens, a 2.5in LCD screen and 19 shooting modes. The Ixus 85 IS sports the same silver casing as its predecessor but Canon has tweaked its looks to give the Ixus line-up "softer curves". There's also a bold lens ring and edging details in piano black or silver.

The final addition to the range is the Canon Digital Ixus 90 IS. The 10Mp camera features a 3x optical zoom lens and 19 shooting modes like its sister model the Ixus 85 IS but it also benefits from a flat key control panel and thumb wheel and has a slightly larger 3in LCD screen.

All three cameras will be available from the end of March. Each has face-recognition capabilities and is able to track subjects so they remain the focus of the shot. Motion Detection and Image Stabilising technology to ensure that all images are clear, sharp and blur-free.
