Pre-Photokina 2008: Canon has announced a pair of 10 megapixel successors to its PowerShot S5IS 'super zoom' compact digital camera. Both the PowerShot SX10 IS and PowerShot SX1 IS feature 28-560mm (equivalent) 20x zoom lenses, DIGIC IV processors, improved image stabilization system and wealth of new features. The SX1 IS is particularly interesting as it is the first PowerShot to feature a Canon CMOS sensor, which allows the camera to offer 4.0 fps (full resolution) continuous shooting and true 1080p HDTV movie capture at 30fps. UPDATE: The SX1 has now been launched in the US and RAW capability added for existing users.
