Canon EF-S 17–55mm f/2.8 IS USM is a versatile APS-C zoom with constant f/2.8 aperture and three-stop image stabilization, suitable for events, general photography, and portraits. Two low-dispersion elements reduce aberrations. Ring-type USM autofocus is fast and silent, with a rounded diaphragm for smooth bokeh. The extending front barrel complicates use of circular filters. Included: Canon EF-S 17–55mm f/2.8 IS USM lens, front and rear caps, 77 mm UV filter, pouch.
