The 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. A Super Spectra coating is also featured and minimizes flare and ghosting in order to produce greater contrast when working in bright lighting conditions. Benefitting both photo and video applications, an STM stepping AF motor is used to realize quick and near-silent autofocus performance along with full-time manual focus override. One Ultra-Low Dispersion glass element noticeably reduces color fringing and chromatic aberrations for high clarity and color fidelity. 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.
