Combining exceptional optical performance with an extremely popular focal length range, the EF-S 17-55mm f/2.8 IS USM is a superbly built standard zoom lens that could easily find a home in any professional or amateur photographer's kit. Nicely sized, this mid-weight lens is comfortable to carry and to handle. Combine that easy weight with a wide f/2.8 aperture and excellent 3-stop Image Stabilisation, and handholdability becomes a breeze. With its handy focal length range, you will find a million and one uses for this lens, from landscapes and portraits, to events and family days out. Of course, a useful focal length range is nothing without image quality. Luckily, the EF-S17-55mm f/2.8 IS USM excels at both. Utilising L-series grade UD lens elements, a fast, accurate ring-type USM autofocus and a circular seven-blade aperture, this lens delivers razor sharp images, beautiful bokeh, and well controlled chromatic aberration, distortion and vignetting.
