Canon EF 70-200mm f/4L USM Lens

The Canon EF 70-200mm f/4L USM is a telephoto zoom lens built around Canon’s L-series optical standards, covering a versatile range suitable for portraiture, sports, wildlife, and event photography. The constant f/4 maximum aperture is maintained throughout the zoom range, providing consistent exposure and depth of field control. Canon’s Ring-type USM (Ultrasonic Motor) delivers fast, quiet autofocus with full-time manual focus override. The optical design incorporates fluorite and Ultra-low Dispersion (UD) glass elements to minimize chromatic aberration and maintain sharpness and contrast across the frame. At a relatively compact size and weight for its class, the lens balances well on a range of EF-mount bodies and is compatible with Canon EF teleconverters for extended reach.
