The EF-S 17-85mm f/4-5.6 IS USM Lens from Canon is a lightweight, compact all-purpose "standard" zoom lens with a focal length equivalent
to 27-136mm in the 35mm format. It is compatible with DSLR cameras that use the APS-C format and provides a versatile set of focal lengths
from wide-angle to telephoto.

This lens features Canon's optical Image Stabilization technology, providing up to a 3-stop compensation for image blur caused by camera
shake at slow shutter speeds. A ring-type ultrasonic autofocus motor provides fast and silent autofocus action and full-time manual focus
is supported even when in the AF mode.

Designed specifically for digital photography, it has a 17 element, 12 group construction, including one double-sided aspherical element
for reduced aberrations and crisp, high contrast corner-to-corner detail. Canon's specialized lens coatings suppress ghosting and flare and
an optional dedicated lens hood can further reduce the incidence of flare. A rounded 6-blade aperture provides pleasing out-of-focus
backgrounds when shooting with a shallow depth of field.

    Uses optics made to take full advantage of the small image circle and short back focus in EF-S lenses designed for APS-C format cameras.
    Image Stabilizer gives equivalent effect of a shutter speed three stops faster during hand-held shooting.
    Ring-type ultrasonic autofocus motor (USM) provides quiet, fast, precision auto focusing and predictive tracking.
    Manual focus override allows precise manual focus control even when shooting in AF mode.
    Aspherical lens elements minimize aberrations for high image quality at all focal lengths.
    Optimized lens coating minimizing flare and ghosting prone to occur with digital cameras.
    Circular aperture diaphragm produces brilliant out-of-focus characteristics
