Canon EF-S 17-85mm f/4-5.6 Image Stabilized USM

The EF-S 17-85mm f/4-5.6 IS USM provides an effective focal length range of approximately 27-136mm in 35mm format. This provides plenty of framing options, making it the perfect all-purpose lens that allows you to express your creativity in a vast range of shooting situations.

Light and fast
The small size and low weight of the EF-S 17-85mm f/4-5.6 IS USM make it ideal for fast moving photography and travel, where it is not practical to carry around a heavy bag of kit. Its ring-type USM works in concert with EF-S mount EOS cameras to provide super-fast, precision auto focusing and predictive tracking - with full manual override available at any time.

Go steady
Image Stabilizer technology compensates for a full three stops, giving the lens an effective maximum aperture of f1.4-2.0; excellent for hand-held and low light photography.

Designed for digital
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. An exclusive optional lens hood can further reduce the incidence of flare.

Background blur
A circular aperture provides a pleasing background blur when shooting with a wide aperture; ideal for creating a sense of depth and getting your subject or model to stand out from the background.
