Canon RF 100-400mm f/5.6-8 IS USM Lens

The Canon RF 100-400mm f/5.6-8 IS USM is a lightweight, versatile super-telephoto zoom lens designed for Canon RF-mount full-frame mirrorless cameras. Ideal for wildlife, sports, travel, and outdoor photography, this portable zoom delivers impressive reach in a compact form factor, making it an excellent choice for photographers who need flexibility without excess weight.

Covering a broad 100–400mm focal length range, the lens packs serious telephoto power while maintaining a modest f/5.6–8 maximum aperture to keep size and weight down. Optical performance is enhanced by an Ultra Low Dispersion (UD) element and an aspherical element, which work together to reduce chromatic aberrations, control distortion, and maintain high sharpness and clarity throughout the zoom range. Canon’s Super Spectra Coating further minimizes flare and ghosting, ensuring strong contrast and accurate color even in challenging lighting conditions.

For sharp handheld shooting, the Canon RF 100-400mm features Optical Image Stabilization rated up to 5.5 stops, with up to 6 stops available when paired with compatible Canon cameras using Coordinated IS with in-body image stabilization. Fast, accurate, and nearly silent autofocus is driven by a Nano USM system, combining the speed of ring-type USM with the smooth operation of STM—perfect for both still photography and video recording.

Despite its long reach, this lens also excels at close-up shooting. It offers close-focusing performance throughout the zoom range, with a maximum magnification of 0.41x at 400mm and a minimum focusing distance of just 2.9 feet at 200mm, allowing you to capture detailed images of smaller subjects. A rounded 9-blade diaphragm produces smooth, pleasing background blur, while the customizable Control Ring provides quick access to exposure settings such as aperture, ISO, or exposure compensation.

For even greater reach, the Canon RF 100-400mm f/5.6-8 IS USM is compatible with the optional Canon RF 1.4x and RF 2x extenders, making it a highly adaptable telephoto solution for photographers who need maximum versatility in the field.
