Canon EF 400mm f/2.8L IS III USM Lens

Canon's new EF 400mm f/2.8L IS III USM lens has been redesigned to be significantly lighter than its Mark II predecessor, making it the world's lightest 400mm f/2.8 lens. This reduced weight lends itself to better handling and balance, allowing you to shoot comfortably for longer. The fast f/2.8 aperture lets in more light to compensate for dim environments, perfect for indoor sports. Image stabilisation helps counteract camera shake and movement, especially when shooting handheld.

400mm Super Telephoto Focal Length

The Canon EF 400mm f/2.8 mark III is a super telephoto lens designed for full frame sensor cameras or APS-C size sensors where it provides a 35mm equivalent focal length of 640mm. At up to 25% lighter than its predecessor, this purpose built lens is perfect for sports or wildlife photography where getting physically close to your subjects may not be safe or possible.

Fast f/2.8 Aperture

A bright f/2.8 aperture really works a treat in dimly lit conditions. Whether you're shooting outdoors at dusk or indoors at a sports stadium, the wide aperture gathers more light and allows you to use the quicker shutter speeds often needed to capture moving or distant subjects. It also creates a beautifully shallow depth of field for more dramatic looking action images.

Image Stabilisation

Building on the above features, the lens also has powerful image stabilisation (up to 5 stops) to help counteract any camera shake and movement. As this is especially noticeable in the longer focal lengths, IS goes a long way toward ensuring your images remain sharp and detailed, even when shooting handheld.

Ring-Type USM Autofocus Motor

Driving the 400mm f/2.8 lens's autofocus system is a ring-type Ultra Sonic Motor (USM) and high-speed CPU. This combination provides fast, accurate, and quiet autofocus that tracks well, especially with image stabilisation. For more control, moving into manual focus is as easy as flicking a switch.

Customisable Electronic Focus Control

The electronic manual focusing ring is also incredibly customisable, with 3 sensitivity levels that let you choose how fast and how precisely to adjust your focus. This can be helpful when shooting different types of subjects depending on how much or how quickly they're moving. Two presets can be assigned to the focus recall ring which only needs a simple twist to switch between them.

Canon L Series Optical Quality

Following in the footsteps of L series lenses before it, the EF 400mm f/2.8 III is made with the same impeccable optics and attention to detail. The lens perfectly complements Canon's high-resolution image sensors, delivering detailed, professional quality results every time.

17 Elements in 13 Groups

A newly arranged optical design consists of 17 elements in 13 groups, including 2 Flourite elements and 1 Super Ultra-Low Dispersion element. These help control chromatic aberrations and distortion for images with better edge-to-edge contrast and detail.

Anti-Reflective Multi-Coated Optics

Special coatings have also been applied to the lens optics including an Air Sphere Coating to minimise glare and reflections for sharp images with better detail. There's also Canon's Super Spectra Coating (SSC) for improved colour fidelity and contrast.

9 Aperture Blades for Better Bokeh

A rounded 9-blade aperture creates a more circular looking 'bokeh' effect in out of focus areas and highlights of your image. Combined with the compression of a telephoto lens, this results in a smooth, softly blurred background that contrasts beautifully against your in-focus subject while eliminating any distracting background elements.

Durable, Water-Resistant Construction

Of course, it wouldn't be an L series lens without mentioning build quality. The Canon 400mm f/2.8L USM is no exception, with a rugged dust and water-resistant construction that lets you shoot confidently in harsh weather. Even the paint formula is new and, together with its two-layer barrel structure, is designed to reflect more heat than ever before to keep your lens working reliably.
