The Canon EF 70-200mm f/2.8L USM lens extension for the EOS single-lens reflex camera is a telephoto zoom lens that performs excellent over the entire zoom range. The lens is part of the L-series, which makes it extremely suitable for professional photography. The quality is sharply monitored by 4 UD elements. They ensure that chromatic aberrations won't influence
the contrast and color of your photos. The Inner and Rear Focusing really boost the AF system. Your subject is focussed at high speed and with great precision. Of course, this process takes place peacefully. The silent Ultra Sonic Motor (USM) technique works the focus system hard but silently.
