Canon EF 28 300mm f/3.5 5 6 L IS USM lens

A true all-in-one lensWith a zoom range covering everything from wide-angle to super-telephoto, Canon's latest professional series is designed for professional photographers looking to limit lens changes and reduce overall kit weight. Perfect for photojournalists and those shooting on the move. Ultrasonic focusingA ring-type ultrasonic motor drives autofocus extremely quickly, and in near silence. Excellent holding torque ensures the point of focus is reached accurately, without overshooting. Furthermore, full-time manual override is available, making it possible to adjust focus without leaving AF mode. Precision optics for high image qualityBeautiful contrast, low distortion and high corner-to-corner resolution is evident throughout the zoom range. An EMD (electromagnetic diaphragm) gives fast, quiet, highly precise aperture control. A circular aperture diaphragm affords pleasing background blur. Three-stop Image StabilizerThe IS technology built-in to the EF 28-300mm f/3.5-5.6L IS USM lens provides a three-stop advantage in low light conditions. This enables slower shutter speeds to be used without incurring blur from camera movement - useful when a situation does not permit the use of a tripod or flash. If the lens senses the photographer is panning to follow a moving subject, it switches off IS in this direction. Perfect for digitalLens shape and coatings have been optimised to suppress ghosting and flaring, making the EF 28-300mm ideal for use with digital cameras. When fitted to DSLRs with an APS-C size sensor, the lens has an equivalent focal length range of 45-480mm.
