The RF 100-400mm F5.6-8 IS USM is designed for photography enthusiasts who need more focal length but do not want the cost, extra weight, and size of a more specialized lens. As an entry-level model in the RF zoom lens lineup, it sits below the RF 100-500mm F4.5-7.1 L IS USM. It is the lightest super-telephoto zoom in its class, weighing only 635 g and is extremely compact. The optical image stabilizer offers 5.5 stops (6 stops of coordinated IS), and the very fast Nano USM autofocus ensures outstanding performance. The minimum focusing distance reaches a scale of 1:2.4 (0.41x). A separate control ring makes operation easy. It is the ideal complement to the RF 24-105mm F4-7.1 IS STM, compatible with RF extenders, and perfect for professionals and enthusiasts, suitable for travel, wildlife, sports, and train/plane spotting.
