The Canon EF 24-70mm f/2.8L II USM Lens from Canon ups the ante for optical performance for a professional standard zoom lens. It has one Super UD lens element and two UD lens elements that minimize chromatic aberrations in the periphery at wide-angle, as well as reducing color blurring around the edges of the subject. In addition, two types of aspherical lenses are combined to help reduce spherical aberration over the entire image area, as well as through the full zoom range. Optimized lens coatings help ensure exceptional color balance while minimizing ghosting.
