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

The Canon RF 100-400mm f/5.6-8 IS USM Lens is a versatile telephoto zoom lens designed for Canon EOS R-series mirrorless cameras. It provides an impressive 100-400mm focal length range in a compact and lightweight body, making it an excellent choice for photographers who want extended reach without carrying a large professional telephoto lens.

This lens is designed for photographers who enjoy wildlife photography, sports, travel, outdoor events, bird photography, and nature photography. The 400mm maximum focal length allows users to capture distant subjects with impressive detail while maintaining a comfortable shooting distance. 

The variable f/5.6-8 aperture design helps keep the lens compact, affordable, and portable while still delivering excellent telephoto performance. At 100mm, the lens provides flexibility for portraits and general telephoto shooting, while extending to 400mm gives photographers the reach needed for wildlife and action photography.

Canon designed this lens with an advanced optical construction featuring 12 elements in 9 groups, including a UD glass element and an aspherical element. These optical components help reduce chromatic aberration, distortion, and image imperfections while maintaining sharp and colorful images throughout the zoom range. 

The built-in Nano USM autofocus system delivers fast, accurate, and quiet focusing, making the lens suitable for both photography and video recording. Combined with Canon EOS R autofocus technologies, it provides reliable subject tracking for moving subjects.

The lens also includes Optical Image Stabilization with up to 5.5 stops of correction, helping photographers capture sharper handheld images. When paired with EOS R cameras featuring in-body stabilization, coordinated stabilization can provide up to 6 stops of correction.
