Perfect for wildlife, sports, travel and more, the RF 100-400mm f/5.6-8 IS USM is a compact, lightweight telephoto lens for EOS R Series cameras, offering a versatile zoom range that brings subjects closer with ease. The RF 100-400mm f/5.6-8 IS USM is similar in size to the EF 70-300mm f/4.5-5.6 IS II USM lens, and not only reaches to 400mm, but also has fast Nano USM focusing and up to 6 stops of Coordinated IS when used in combination with an EOS R series camera featuring In-body Image Stabilization, like the EOS R5 and EOS R6, or 5.5 stops with an EOS R/RP camera. Using a single Ultra Low Dispersion lens element towards the front of the lens group corrects chromatic aberration throughout the entire zoom range, making your images look crisp and colorful with minimal color blur. The RF 100-400mm f/5.6-8 IS USM lens can also accept both the RF 1.4x and RF 2x tele extenders giving you the effective maximum focal length of 560mm and 800mm respectively. With a control ring that allows for quick setting changes, including shutter speed and aperture, the RF 100-400mm f/5.6-8 IS USM lens puts quality, convenience and control in your hands.
