Optically identical to the super-telephoto EF 400mm f/2.8L IS III USM lens, the Canon RF 400mm f/2.8L IS USM Lens delivers high-performance results and is a go-to choice for capturing professional-quality shots of sports, wildlife, and more.
Designed exclusively for EOS R-series cameras, the lens features three modes of optical image stabilization with up to 5.5 stops of shake correction to deliver extremely sharp results whether hand-held or mounted on a monopod. A circular nine-blade aperture provides beautiful bokeh at smaller lens apertures, and Super Spectra and Air Sphere Coatings minimize ghosting and flare for exceptionally clear results when shooting in backlit situations. Additionally, Super UD and fluorite elements used in the optical design reduce colour fringing and chromatic aberrations for high clarity and colour accuracy.
Two focus presets allow you to instantly return to one or two memorized focus distances, and a customizable electronic focus ring allows manual focusing during SERVO AF. The RF 400mm f/2.8L IS USM Lens is also compatible with Canon RF 1.4x and 2x Extenders, and the lens incorporates a dust and water-resistant design with a fluorine coating on the front element for easy cleaning.
The same high image quality is maintained in the RF400mm F2.8 L IS USM as of of the EF 400mm f/2.8L IS III USM with outstanding sharpness and contrast, center to corner, even at maximum aperture.
A combination of Fluorite and Super UD (Ultra-low Dispersion) glass is at the heart of this lens’s outstanding optical performance. At the widest aperture of f/2.8, chromatic aberration is significantly reduced, to achieve tack-sharp images with minimal colour fringing. This means detailed results in any shooting condition, particularly in low light levels.
Optically Identical to EF 400mm f/2.8L IS III USM lens
The latest EF version of the 400mm f/2.8L IS lens, preserved the legendary sharpness of previous EF 400mm f/2.8L lenses, but with a dramatic reduction in overall weight. The RF version preserves this advantage, providing outstanding handling for a super-telephoto lens with an f/2.8 maximum aperture. And, since it uses the same optical design as the EF version III lens, the same superb image quality can also be expected.
Minimum Focusing Distance of 2.5 m
With a minimum focusing distance of approx. 2.5m, the RF 400mm F2.8 L IS USM helps you get close to your subjects. At its closest focus distance, you can fill the frame with a subject roughly the size of an adult’s extended hand, from wrist to fingertips.
Compatible with Canon RF 1.4x and 2x Extenders
To help get you even closer to the subject, attach the compatible Extender RF 1.4x or Extender RF2x to the RF400mm F2.8 L IS USM. Expand effective telephoto power to 560mm at f/4 with the Extender RF 1.4x, or to effective 800mm at f/5.6 using the Extender RF2x.
9-blade Circular Aperture for Beautiful Bokeh
Thanks to its 9-blade, circular aperture, the RF 400mm F2.8 L IS USM 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 and videos for impactful results.
Dust- and Water-resistant Design, with Fluorine Coating on Front Element for Easy Cleaning
Built to L series lens specifications, the RF400mm F2.8 L IS USM features a highly durable design for excellent performance even in inclement weather conditions. The dust- and water-resistant construction includes seals around the mount, switches, rings and more.
To help maintain a clean lens, even after multiple lens changes in sub-optimal conditions, the RF400mm F2.8 L IS USM has a specially designed fluorine coating on its front and rear surfaces. The coating helps to prevent water, oil and other surface residue like fingerprints from sticking to the lens, which facilitates quick and easy wiping, without the use of solvents.
The RF400mm F2.8 L IS USM features an Optical Image Stabilizer system that provides up to 5.5 stops of shake correction, delivering consistent and sharp results. Whether hand-held or mounted on a monopod, the lens’s Image Stabilization can deliver clear image detail in low-light situations or at lower ISOs for both stills and video.
Three IS Operation Modes
Three image stabilization modes provide shake-correction for outstanding results in a wide range of shooting situations.
The Canon RF 400mm F2.8 L IS USM lens delivers outstanding images and video, even at maximum aperture, in harsh back-lighting conditions - thanks to Canon's Super Spectra Coating (SSC) maintaining overall image quality and colour fidelity, as well as Air Sphere Coating (ASC), which significantly helps to reduce the occurrence of lens flare and ghosting.
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. Additionally, depending on camera settings, manual focus is still possible while AF is engaged, letting you fine-tune focus adjustments to suit your shooting preferences.
Two Focus Presets Available
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. Then, with a simple twist of the playback ring, immediately jump back to one or the other.
