Canon EF-S 10-22mm f/3.5-4.5 USM Lens - The EF-S 10-22mm f/3.5-4.5 USM Lens from Canon is an ultra wide-angle zoom lens with dynamic expressive capability and a lightweight build for all EF-S mount digital EOS cameras.With an effective focal length range of approximately 16-35mm in 35mm format, this lens allows you to get extremely close to subjects, exaggerating the difference in size between a near object and its background. Creative photographers can use this phenomenon to create excellent separation between subject and background for a strong sense of presence, or for a pan-focus effect with everything from foreground to background sharply in focus. An Ultrasonic Motor (USM) provides fast, smooth and quiet autofocus action and manual focus override in the One Shot AF mode enables precise focusing at all times.
