Canon EF - Zoom lens

With an ultra-high approx. 11x zoom range covering everything from wide-angle to super-telephoto, Canon's latest professional series 'white lens' is designed for professional photographers looking to limit lens changes and overall kit weight. With Image Stabilization (IS) and high speed, silent auto focus, this superbly specified lens delivers what others can only imagine.

Canon's renowned IS technology compensates for approximately three stops with no perceptible increase in image blur. This vastly increases the range of circumstances in which hand-held photography is possible, limiting the need to carry a tripod. Major movement in a specific direction is detected as conscious panning and correction is halted in the relevant direction, thereby preventing shake-return.

The ultrasonic motor (USM) converts ultrasonic vibration energy into rotational force to deliver high-speed, high-precision, super efficient and virtually noiseless auto focusing, with good holding torque for rapid response, accurate stopping. The lens has full-time manual override. The 0.7m minimum focusing distance throughout the entire zoom range also makes it ideal for close-up magnifications.

Lens shape and coatings have been optimized to suppress ghosting and flaring, making the lens ideal for use with digital cameras that can be susceptible to reflections off the recording sensor. When fitted to digital cameras with an APS-C size sensor such as the EOS 10D, the lens has an equivalent focal length range of 45-480mm.

Beautiful contrast, low distortion and high corner-to-corner resolution is evident throughout the zoom range. An EMD (electromagnetic diaphragm) controls aperture for fast, quiet, highly precise control. A circular aperture diaphragm affords pleasing background blur, from full aperture to two stops down.

The EF 28-300mm features a rugged dust-proof and drip-proof construction, designed for professionals working under a wide range of harsh conditions.

The drive pattern is tailored to match the latest EOS range, extracting maximum benefit from the lens' speed advantage. Distance information offers higher precision focus-linked E-TTL II flash photography metering.
