The EF-S 17-55mm f/2.8 IS USM Lens from Canon
is a large-aperture lens compatible with APS-C format digital SLR
cameras, and offers a versatile wide-angle to short telephoto zoom
range. The focal length is equivalent to approximately 27-88mm in 35mm
format and its constant f/2.8 maximum aperture is effective in low light
throughout the zoom range. A wide maximum aperture also enables shallow
depth of field control.
This lens features Canon's optical Image
Stabilizer technology, providing up to 3-stop compensation for image
blur caused by camera shake at slow shutter speeds. This enables clear
images, even in dim light. An ultrasonic autofocus motor (USM) provides
fast and quiet AF action which is particularly important when shooting
video and manual focus override allows precise manual focus at any
moment, even in autofocus mode.
Designed specifically for digital
photography, the lens has specially shaped lens elements and Super
Spectra coatings to suppress ghosting and flare, which can be caused by
reflections off digital camera sensors.
