Flexible APS-C standard zoom
The Canon EF-S 17-55mm f/2.8 IS USM is a constant-aperture zoom designed for APS-C DSLRs. Its 17-55mm focal range delivers a 27.2-88mm equivalent view suited to everyday photography. The bright f/2.8 maximum aperture stays constant throughout the range, aiding low-light work and depth-of-field control. Two UD and three aspherical elements plus Super Spectra coating reduce aberrations, flare and ghosting.
Check mount and sensor format
This lens uses the EF-S mount and covers only APS-C image circles, so it will not function on full-frame Canon bodies. Confirm your camera accepts EF-S lenses before ordering. The aperture stops down to f/22 for extended depth of field when needed. No adapter or firmware update is mentioned in the supplied data.
Ring USM focus with stabilisation
A ring-type ultrasonic motor provides quick, quiet autofocus with full-time manual override for tactile adjustments. The built-in optical Image Stabilizer is rated for three stops of shake correction during handheld shooting. A rounded seven-blade diaphragm produces smooth background blur. The lens is supplied new in its original packaging.
