Canon RF 70-200mm f/2.8L IS USM Lens

Designed for use with the full-frame Canon RF-mount mirrorless cameras, the notably sleek Canon RF 70-200mm f/2.8L IS USM offers a standard to telephoto focal length range suitable for a myriad of photography applications. Its constant bright f/2.8 maximum aperture makes it possible to work in a variety of available lighting and affords a greater control over depth of field. Optically, the lens design incorporates one UD (Ultra-Low Dispersion) element, one Super UD element, and two aspherical elements to correct various abberations for clearer, sharper and more accurate imagery. To reduce backlit flaring and ghosting in harsher lighting conditions, an Air-Sphere Coating (ASC) has been applied to the lens elements.

This versatile lens is driven by a Dual Nano USM (Ultrasonic Motor) focus system which combines both a ring-type USM and the STM (Stepper Motor) mechanism to achieve fast, smooth, and almost silent autofocusing capabilities that benefits both still and video shooting; If required, full-time manual override for refined focusing is available when working in the the one-shot AF mode. An integrated Control Ring provides intuitive control over exposure settings, including aperture, ISO, and exposure compensation, from the lens itself. An Optical Image Stabiliser, which helps to minimise the appearance of camera shake by five stops, is built into the lens design for sharper handheld shooting, especially in challenging lighting conditions and slower shutter speed. In addition to the weather-sealing that renders the lens dust- and moisture-resistant, the front and rear elements of the lens received a fluorine coating to resist fingerprints and smudges as well as to significantly ease the cleaning of the lens. The lens features a rounded nine-blade diaphragm that contributes to a pleasing bokeh quality.
