One of the big attractions of the Canon EF-S 17-55mm f/2.8 IS USM is the large maximum aperture. This gives you the ability to use faster shutter speeds. You are likely to find this particularly useful when light is fading as you will be able to handhold your camera for longer without blurring your photos. The f/2.8 aperture is available throughout the zoom range.
Canon have also included image stabilisation as a further measure to counter unwanted blur. In addition the EF-S 17-55mm f/2.8 IS USM has a ultrasonic motor (USM). This helps to ensure focusing times are kept to a minimum.
