With an approx. 11x zoom range covering everything from wide-angle to telephoto this latest dust and moisture proof \'white lens\' is designed to appeal to professional EOS photographers looking to reduce lens changes and the number of lenses they need to carry. Image Stabilisation The lens incorporates Canon\'s Image Stabilisation (IS) technology allowing you to shoot at slower shutter speeds without seeing any increase in the effects of camera shake. This increases the range of circumstances in which hand-held photography is possible limiting the need to carry a tripod. With major movement in a single direction such as panning the camera IS Mode 2 automatically determines that the movement is intentional and does not try to overcome it. The system also automatically detects a lack of movement/vibration in order to prevent over-correction when a tripod is used. Fast Auto-Focus The ring-type ultrasonic motor (USM) converts ultrasonic vibrational energy into rotational force to deliver high-speed high-precision super efficient and virtually noiseless auto focusing. It offers good holding torque for rapid response and accurate stopping. Full-time manual override without damage to the autofocus mechanism is featured. Minimum focusing distance is just 0.7m throughout the entire zoom range. Ideal for digital The lens element design and coatings have been optimised to suppress ghosting and flaring. This makes the lens ideal for use with digital cameras that are more susceptible to reflections off the recording media than film cameras. Precision optics for high image quality 22 lens elements in 16 groups offer low distortion and high corner-to-corner resolution throughout the entire zoom range. As with all EF lenses the aperture is controlled by an EMD (electromagnetic diaphragm) for fast quiet and precise control. A circular aperture diaphragm is used to give attractive background blur from full aperture to two stops down. The use of three ultra-low dispersion (UD) glass elements effectively reduces the residual chromatic aberrations that can plague lesser quality long lenses. At the same time aspherical elements correct various kinds of aberration that occur during zooming to give the lens the unsurpassed clarity and resolving power that are expected from Canon\'s professional L-series lenses. Zoom Adjust A zoom adjust mechanism allows sensitivity of the zoom movement to be adjusted to suit personal preferences. The zoom can be locked at any focal length. Environmental protection The EF 28-300mm f/3.55.6L IS USM features a rugged dust and water resistant construction designed for professional photographers working in harsh environments under a wide range of operating temperatures and humidities. Working with EOS The drive pattern of the lens is tailored to match that of the latest EOS camera range extracting maximum benefit from the speed advantage of the lens. Environmental control In keeping with Canon\'s stringent environmental policy only lead-free glass is used in the optics. ?
