The Canon EF-S 55-250mm f/4-5.6 IS STM is an 88-400mm-equivalent zoom for Canon APS-C DSLRs. This lens's long reach is enhanced by the inclusion of an Ultra-Low Dispersion element, which helps to greatly reduce color fringing and chromatic aberrations for greater clarity and color accuracy throughout the zoom range. Canon EF-S-mount DSLRs provide an 88-400mm equivalent focal length range. An Optical Image Stabilizer helps to minimize the appearance of camera shake by up to 3.5 stops to better enable working in low-light conditions and with slower shutter speeds. Enhanced lens coatings minimize flare and ghosting in order to produce true colors with maintained contrast. An STM stepping AF motor realizes smooth, near-silent autofocus that is complemented by a rear focus system advanced AF algorithms, and a high-speed CPU for fast AF performance. The rounded seven-blade diaphragm contributes to a pleasing out-of-focus quality that benefits the use of shallow depth of field and selective focus techniques.
