Overview
High-performance, Wide-aperture 400mm f/2.8 Super-telephoto Lens, Exclusively for EOS R-series cameras.
Inheriting the optics of the EF 400mm f/2.8L IS III USM, the same high image quality is maintained in the RF400mm F2.8 L IS 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.
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. The extenders allow even more telephoto reach when it’s needed, yet allow the user to convert back to an f/2.8 lens for low-light situations by simply removing the extender.
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 (IS Mode 1); helping to correct camera shake when intentionally panning horizontally (or vertically), providing shake-correction perpendicular to the photographer’s panning movement (IS Mode 2); and stabilization that instantly goes into effect only when the shutter is released — no correction visible between shots, in the camera’s viewfinder (IS Mode 3).
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. The “1” position on the M.Focus Speed switch provides the fastest sensitivity (a small amount of focus ring rotation provides significant focus change in the lens); settings 2 and 3 reduce this sensitivity, allowing for finer manual focus adjustments.. This can help whether you need a slow speed to switch between someone’s eyes in a distant profile, or a fast speed to dial in on different birds in a large, swiftly moving flock. 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.
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. It delivers a dust- and water-resistant construction with 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
