Delivering high-performance for professional photographers as well as inheriting the optics of the EF 400mm f/2.8L IS III USM model, the RF 400mm F2.8 L IS USM is the go-to choice to help capture superb shots of sports, wildlife and more. Its optical image stabilization system with up to 5.5 stops* of shake correction, including three IS operation modes, helps to deliver sharp results – whether hand-held or mounted on a monopod. For brilliantly clear results even in challenging situations, Super Spectra Coatings (SSC) and Air Sphere Coatings (ASC) help minimize ghosting and flare. The RF400mm F2.8 L IS USM is also compatible with both the RF 1.4x and 2x Extenders to get you even closer to the subject.
