This is a brand new, updated version of the classic Canon wide zoom lens. Featuring a series of specialized elements, this lens utilizes a trio of aspherical elements and two ultra-low dispersion glass elements to control a variety of aberrations for high sharpness and clarity. Both SWC and ASC coatings have also been applied to the elements in order to reduce lens flare and ghosting for increased contrast and color accuracy.
