The PowerShot SX40 HS is equipped with a Genuine Canon 35x Zoom lens that provides the telephoto power to bring your distant subjects incredibly close. It also features a useful zoom range that begins at 24mm wide-angle and extends to 840mm telephoto (35mm equivalent). The 24mm ultra Wide-Angle allows you to create shots with dramatic perspective and makes it easy to shoot sweeping landscapes, large groups of people and tall buildings. This superb lens delivers outstanding optical performance throughout its zoom range. It's advanced design employs UD glass, double-sided aspherical glass-molded and ultra-high-refraction-index glass lens elements to effectively suppress chromatic aberration while maintaining a remarkably compact size. The camera uses a VCM (Voice Coil Motor) for high-speed, quiet, energy-efficient lens movement with precise control.
Optical Image Stabilizer
Handheld shooting can often lead to camera shake, making photos and videos blurry. Canon's Optical Image Stabilizer is a sophisticated system that uses lens-shift technology to correct for unwanted camera movement. It makes handheld photography more practical, providing excellent image quality in many difficult shooting situations: outdoors at dusk, inside without a flash, and even at the telephoto end of the zoom range without a tripod. For photos, it enables shooting at slower shutter speeds, accommodating more low-light shooting situations than ever before without having to boost ISO sensitivity. With camera shake and vibration reduced, you get a sharper, steadier image. And because it is an optical system, there is none of the image degradation typical with electronic image stabilizers.
