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.
Image Stabilization
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.
Ultra Sonic Motor
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.
Perfect for digital
Lens shape and coatings have been optimised 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.
Precision optics for high image quality
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.
Environmental protection
The EF 28-300mm features a rugged dust-proof and drip-proof construction,
designed for professionals working under a wide range of harsh conditions.
Working with EOS
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.
