The Canon RF 100-400mm f/5.6-8 IS USM is an agile telephoto-zoom with a portable body factor that is ideal for shooting animals, sports, and travel. This zoom's expanded range allows it to achieve super-telephoto reach while maintaining a relatively slim, light design and supporting both Nano USM AF and Coordinated IS, which work together to improve focus performance and reduce camera shake by up to 6 stops.
Throughout the zoom range, the lens' optical design makes use of specialised features to control a number of aberrations and generate images with exceptional sharpness and clarity. With a maximum magnification of 0.41x at the 400mm setting, close-focusing performance is also available for up-close photography of objects as small as a credit card.
- Long-reaching telephoto zoom lens is designed for use with full-frame Canon RF-mount mirrorless cameras.
- Modest f/5.6-8 maximum aperture range promotes a relatively compact, lightweight form factor.
- 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.
- One aspherical element helps control distortion and promotes a high degree of sharpness.
- Super Spectra Coating has been applied to minimize flare and ghosting for improved contrast and color fidelity when working in strong lighting conditions.
- An Optical Image Stabilizer helps to minimize the appearance of camera shake by 5.5 stops to better enable working in low-light conditions and with slower shutter speeds. 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. This focusing system also affords full-time manual focus control when working in the one-shot AF mode.
- 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.
- Rounded 9-blade diaphragm contributes to a pleasing bokeh quality.
- Configurable Control Ring can be used to adjust a variety of exposure settings, including aperture, ISO, and exposure compensation.
- Compatible with optional Extender RF 1.4x and Extender RF 2x teleconverters to further increase the effective focal length.
