The Canon RF 100-400mm f/5.6-8 IS USM is a nimble lens perfect for wildlife, sports, and travel shooting. Optically, the lens uses specialized elements to control a variety of aberrations and produce images with high sharpness and clarity throughout the zoom range. A Long-reaching telephoto zoom lens is designed for use with full-frame Canon RF-mount mirrorless cameras. One Ultra-Low Dispersion element is featured toward the front of the optical design and helps to reduce chromatic aberrations and color fringing throughout the zoom range. Super Spectra Coating has been applied to minimize flare and ghosting for improved contrast and color fidelity when working in strong lighting conditions. Also, when working with select cameras, up to 6 stops of stabilization may be available with the Coordinated Optical Image Stabilizer and In-Body Image Stabilizer. Nano USM system utilizes both a ring-type USM and an STM mechanism to realize quick and accurate focusing that is also smooth and near-silent to suit both photography and video applications. Close focusing capabilities are available throughout the zoom range, with a maximum magnification of 0.41x available at the 400mm position and a minimum focusing distance of 2.9' possible at the 200mm position. Configurable Control Ring can be used to adjust a variety of exposure settings, including aperture, ISO, and exposure compensation.
