Whether the action is fast or slow, close up or far away, you'll always get the shot you want with the PowerShot SX10 IS. This camera puts you on the cutting edge of advanced technology, with an incredibly powerful 20x optical zoom, 10-megapixel resolution, and DIGIC 4 image processor for high-performance face and motion detection. The PowerShot SX10 IS is equipped with a 20x optical zoom lens with a focal length of 5.0-100mm that allows you to shoot any scene from wide-angle to telephoto. The camera uses a VCM (Voice Coil Motor) for high-speed, quiet, energy-efficient lens movement with precise control. Focal length is conveniently indicated on the lens barrel. The lens is optimized to fully exploit its zoom length and wide shooting angle in concert with the camera's high 10.0-megapixel resolution. UD glass effectively suppresses chromatic aberration, while enhanced negative refractive power ensures that distortion at the wide-angle is also corrected. Further aberration is controlled with the inclusion of a double-sided aspherical glass-molded lens and ultra-high refraction index lens. The SX10 IS is equipped with Canon's acclaimed optical image stabilizer technology that automatically detects and corrects camera shake - one of the leading causes of fuzzy or blurred shots. Even when zoomed in, you can get the steady, crisp, brilliant images you'll be proud to shoot and share. And Canon's optical image stabilizer technology is convenient to use. It functions perfectly with or without a flash.
