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.
What to say here...this lens is great. Though its only an f/4 which, yes, is a bummer. There's a reason why this lens is the go-to workhorse for just about every low-budget doc or reality shoot. I haven't been on a reality shoot in the last 5 years where this lens wasn't there. It's perfect for exterior, run-and-gun shooting. With image stabilization, going handheld is no issue. A must have for any Canon DSLR camera or low-budget shooting.
