Product Description

 Spanning a popular and versatile range of focal lengths, the EF 24-70mm f 2.8L II USM is a Canon L-series zoom commonly thought of as the workhorse of lenses. Ranging from wide-angle to portrait length, this lens is also distinguished by its constant f 2.8 maximum aperture to benefit working in difficult lighting conditions and to afford greater control over depth of field. The lens is also characterized by its sophisticated optical design, which includes one Super UD element and two UD elements, which reduce color fringing and chromatic aberrations in order to realize a high degree of color accuracy and clarity. Three aspherical elements are also featured, and minimize distortion and spherical aberrations for improved sharpness. Additionally, a Super Spectra coating has been applied to individual elements to control flare and ghosting for high contrast and neutral color fidelity.

Balancing the refined optics, this 24-70mm f 2.8 also sports a ring-type USM and internal focusing mechanism to enable quick, quiet, and accurate autofocus performance, as well as full-time manual focus override. Additionally, this lens is weather-sealed and has a protective fluorine coating on the exposed elements for use in trying environmental conditions.
