The Canon RF 70-200mm F4 L IS USM is a telephoto zoom lens designed for the EOS R System. It offers impressive image quality and superb mobility, being one of the shortest and lightest 70-200mm f/4 lenses available. Its compact and portable design makes it ideal for travel. The lens features 4 UD elements to correct chromatic aberration and enhance color vividness, Air-Sphere Coating (ASC) to reduce ghosting, and Optical Image Stabilization (IS) combined with coordinated IS for clear, crisp images and smooth video, even at slow shutter speeds. Dual Nano USMs provide a short minimum focusing distance and high-speed autofocus for stills, as well as near-silent, smooth autofocus for video. With dust- and weather-resistant seals and fluorine coating, this lens is built to perform reliably in various conditions.
