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

Versatile telephoto zoom lens is designed for use with full-frame Canon RF-mount mirrorless cameras. Bright f/2.8 constant maximum aperture maintains consistent illumination throughout the zoom range and suits working in low-light conditions as well as affords increased control over depth of field for working with selective focus techniques. One UD (Ultra-Low Dispersion) element and one Super UD element help to minimize chromatic aberrations and color fringing in order to provide greater clarity and color accuracy. Two aspherical elements are used to correct spherical aberrations and distortion for improved sharpness and accurate rendering. An Air Sphere Coating (ASC) has been applied to lens elements to reduce backlit flaring and ghosting for maintained light transmission and high contrast in strong lighting conditions. An Optical Image Stabilizer helps to minimize the appearance of camera shake by five stops to better enable working in low-light conditions and with slower shutter speeds. Three distinct IS modes are available: standard single-shot mode, a panning-optimized mode, and a mode that only activates the Image Stabilizer during the exposure. Dual Nano USM system utilizes both a ring type USM and an STM mechanism to realize quick and accurate focusing that is also smooth and nearly silent to suit both photography and video applications. This focusing system also affords full-time manual focus control when working in the one-shot AF mode. Configurable Control Ring can be used to adjust a variety of exposure settings, including aperture, ISO, and exposure compensation. Protective fluorine coating has been applied to the front and rear element to resist fingerprints and smudges and to make cleaning these elements significantly easier. As a member of the esteemed L-series, this lens has a weather-resistant design that protects against dust and moisture to enable its use in inclement conditions. Rounded nine-blade diaphragm contributes to a pleasing bokeh quality. Removable rotating tripod collar is included and benefits working with the lens atop a tripod or monopod.
