This easy-to-use standard zoom lens can cover a large zoom area
ranging from 24mm wide-angle to 105mm portrait-length telephoto,
and its Image Stabilizer Technology steadies camera shake up to
three stops. Constructed with one Super-UD glass element and three
aspherical lenses, this lens minimizes chromatic aberration and
distortion. The result is excellent picture quality, even at wide
apertures. Canon's ring-type USM gives silent but quick AF, along
with full-time manual focus. Moreover, with dust- and moisture-resistant
construction, this is a durable yet sophisticated lens that meets the
demands of advanced amateur photographers and professional photographers
alike.
