A tremendously flexible standard zoom for aps-c-format dslrs, the canon ef-s 17-55mm f 2.8 Is usm lens pairs the 27.2-88Mm equivalent focal length range with a bright f 2.8 Constant maximum aperture. Benefitting this design is a sophisticated optical layout, which includes both ultra-low dispersion glass and aspherical elements to significantly reduce chromatic and spherical aberrations for improved clarity and sharpness throughout the zoom range. A super spectra coating has also been applied to individual elements to suppress flare and ghosting for increased contrast when working in bright environments.
Beyond the optical attributes, this 17-55mm is also characterized by its advanced three stop-effective image stabilizer system to minimize the appearance of camera shake. Also complementing handling is a sophisticated ring-type usm, which provides quick, quiet, and accurate autofocus performance along with full-time manual focus override. Key features
