A truly versatile lens, the EF 70-200mm f/2.8L USM is a Canon L-series zoom spanning a flexible range of telephoto focal lengths. Beyond its portrait-length to medium tele range, this lens is also characterized by its bright f/2.8 constant maximum aperture, which affords notable control over depth of field and benefits working in challenging lighting conditions. Supporting the versatility is a sophisticated optical design, which utilizes four ultra-low dispersion elements to suppress color fringing and chromatic aberrations throughout the zoom range for high clarity. Also, a Super Spectra coating has been applied to help reduce lens flare and ghosting for greater contrast and color neutrality. Complementing its optical assets, this 70-200mm f/2.8 also sports a ring-type USM and internal focusing mechanism for quick, quiet, and accurate autofocus performance, as well as full-time manual focus override. Additionally, a removable rotating tripod collar is included for stable use of the lens atop a tripod or monopod.
