The Canon EF-S 17-55mm f/2.8 IS USM is a high-performance standard zoom lens designed for APS-C Canon DSLRs, offering a versatile 27.2-88mm equivalent focal range suitable for landscapes, portraits, events, and everyday shooting. Its constant f/2.8 maximum aperture provides consistent exposure across the zoom range and enables shallow depth of field control for creative subject isolation. The optical design features two ultra-low dispersion elements and three aspherical elements to reduce chromatic and spherical aberrations, delivering sharp images with accurate color and contrast. A Super Spectra coating minimizes flare and ghosting when working in bright or backlit environments, preserving image clarity. Optical image stabilization compensates for up to three shutter speed stops, improving handheld shooting in low-light conditions. A ring-type Ultrasonic Motor provides fast, quiet autofocus with full-time manual focus override for precise control. The internal focusing design enhances handling and maintains lens balance during operation. A rounded seven-blade diaphragm produces smooth background blur for pleasing bokeh effects. Combining reliable performance, optical clarity, and flexible framing, this lens serves as an ideal everyday zoom for photographers seeking professional results across a wide range of shooting situations and lighting conditions.Manufacturer Items Include:Canon EF-S 17-55mm f/2.8 IS USM LensCanon E-77 II Lens CapCanon Lens Dust Cap E (Rear)Bundle Items Include:Canon EF-S 17-55mm f/2.8 IS USM LensLens Case77mm Filter KitLens Cap Keeper
