A streamlined super-telephoto lens, the Canon EF 400mm f/2.8L IS III USM features state-of-the-art optics and image stabilization to help you achieve clear, beautiful imagery—from a distance. This L-series lens maintains a constant f/2.8 aperture, generating bright video and stills, even in low-light situations. The dust- and weather-resistant construction of the Canon EF 400mm f/2.8L IS III USM lens is perfect for wildlife, landscape and sports photographers. The USM provides fast, quiet autofocus performance, while Canon’s proprietary system of lens element coatings deliver clear, accurate color. Three available separate stabilization modes help minimize the appearance of camera shake for consistent, sharp imagery, even while shooting handheld.
Strong and stable
Just like its predecessor, the Canon EF 400mm f/2.8L IS III USM is comfortable to handle; however, a redistribution of weight from the front of the lens to the center makes it much easier to balance when shooting without a tripod. Carefully refined optics, including Super Ultra-low Dispersion (UD) lens elements, significantly reduce the size and the weight of the lens, without sacrificing quality. Reduction in weight of the Image Stabilizer unit also helps contribute to the 25% (about 2.2 pounds) lighter lens. Designed for use even in inclement weather conditions, the Canon EF 400mm f/2.8L IS III USM features dust- and water-resistant seals around the mount, switches and rings, as well as a specially designed fluorine coating on its front and rear surfaces. A reformulated paint helps reflect heat from the sun, and a two-layer barrel structure helps minimize thermal effects on the lens elements.
Precision focusing
The Ultrasonic Motor (USM) in the Canon EF 400mm f/2.8L IS III USM delivers quick, quiet autofocus performance, while a full-time manual focus override is also available. The lens also features a customizable electronic manual focusing ring with three sensitivity levels for different shooting scenarios, as well as two focus presets.
Crisp, clear color
Canon’s proprietary Super Spectra Coating (SSC) and Air Sphere Coating (ASC) have been applied to individual elements in the Canon EF 400mm f/2.8L IS III USM lens. These coatings help eliminate unwanted light wavelengths, minimize flare and ghosting to improve overall image clarity and color fidelity.
Steady, solid performance
To help deliver sharp, consistent imagery, the Canon EF 400mm f/2.8L IS III USM lens features an Optical Image Stabilizer that helps minimize the appearance of camera shake by up to five shutter speed stops. Three separate stabilization modes help provide reliable handheld performance, even in low-light situations.
