The RF70-200mm F4 L IS USM is a telephoto zoom lens delivering impressive image quality along with superb mobility as our shortest and lightest 70-200mm f/4 lens to date. Designed for the EOS R System, this lens takes advantage of the large diameter mount and short back focus distance of the RF mount to maintain high image quality while being more compact and portable so you'll be even more inclined to take it with you on your travels. Results are stunning thanks to 4 UD lenses which help correct chromatic aberration and keep colors vivid, reduced ghosting provided by Air-Sphere Coating (ASC), and Optical Image Stabilization* plus coordinated Optical Image Stabilizer and In-Body Image Stabilizer** for amazingly clear, crisp images at slow shutter speeds and smooth video footage. There's also dual Nano USMs contributing to a short minimum focusing distance and high-speed autofocus for still shooting and near-silent, smooth autofocus during movie shooting. These features and more, combined with the confidence to shoot in almost any condition with dust- and weather resistant seals and fluorine coating, make the RF70-200mm F4 L IS USM lens a solid performer for any situation.
