Delivering high-performance for professional photographers as well as inheriting the optics of the EF 400mm f/2.8L IS III USM model, the RF400mm 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.
Compatible with most Canon EOS mirrorless cameras
For use with your existing RF mount Canon Camera.
Telephoto lens provides detailed photos from a distance
Magnify distant subjects and isolate a small field of view for vivid close-up shots.
400mm focal length for intense magnification
Ideal for wildlife photography, sporting events and any photo shoot that prevents you from getting close to your subject.
f/2.8 maximum aperture
Creates sharp, detailed images with shallow depth of field and softly blurred background. Performs best in moderate-to-bright light settings or outdoors on overcast days.
Optical Image Stabilization with up to 5.5 Stops* of Shake Correction, Including Three IS Operation Modes
Whether hand-held or mounted on a monopod (or other devices allowing mobile positioning), the lens’s Image Stabilization can deliver clear image detail in low-light situations or at lower ISOs.
Three IS Operation Modes
Three image stabilization modes provide shake-correction for outstanding results in a wide range of shooting situations. These include traditional stabilization, with the correction visible any time IS is active in the camera’s viewfinder
Customizable Electronic Focus Ring, with Manual Focus Capability during SERVO AF
The lens’s large manual focus ring is located directly on the lens barrel, and allows you to select from three different manual focus speed levels, to adjust the focus ring rotation to your desired preference.
9-blade Circular Aperture for Beautiful Bokeh
Thanks to its 9-blade, circular aperture, it is capable of gorgeous, evocative out-of-focus areas and soft backgrounds. With rounded rendering of background blur, the 9-blade circular aperture helps create intimacy and intensity in both photos & video.
Two Focus Presets Available — Instantly Return to One or Two Memorized Focus Distances
Quickly select between one or two memorized focus distances, with focus presets. Especially useful for fixed-position sports photography, you can focus upon and memorize two separate focus distances.
Super Spectra Coating (SSC) and Air Sphere Coating (ASC) Helps Minimize Ghosting and Flare
This helps maintain overall image quality and color fidelity, as well as Air Sphere Coating (ASC), which significantly helps to reduce the occurrence of lens flare and ghosting.
Minimum Focusing Distance of 8.20 ft. / 2.5 m.
At its closest focus distance, users can fill the frame with a subject roughly the size of an adult’s extended hand, from wrist to fingertips.
Dust- and Water-resistant Design, with Fluorine Coating on Front Element for Easy Cleaning.
Accommodates 52mm filters
Compatible with Canon RF 1.4x and 2x Extenders
