Canon 400mm f/2.8 L IS III USM Prime - EF Mount

Featuring carefully refined optics, the EF 400mm f/2.8L IS III USM offers a familiar feel to its predecessor while being even more comfortable to handle, thanks to its significantly lighter design. Super UD lens elements provide improved image quality while being more compact in size, and the Image Stabilizer unit weight has also been reduced. Subsequently, this lens is more than 25% (approx. 2.2 lb / 0.99 kg) lighter than its predecessor. Placement of optical elements has also been improved, with the center of gravity now closer to the rear of the lens housing. This allows users to guide the lens more naturally for fast framing of moving subjects.

Super Spectra Coating (SSC) and Air Sphere Coating (ASC) Minimize Ghosting & Flare

To create memorable images with vibrant colors and deep, lifelike contrast, minimizing unwanted flare and ghosting is crucial. Canon’s Super Spectra Coating (SSC) helps reject extraneous light wavelengths, maintaining overall image quality and color fidelity. Additionally, Air Sphere Coating (ASC) minimizes unwanted glare and reflections.

Increased Heat Shielding for Reliable & Longer Outdoor Shooting

The EF 400mm f/2.8L IS III USM delivers consistent and reliable performance, even when used in direct sunlight for extended periods of time. A new paint formulation reflects even more heat than before, while a two-layer barrel structure helps reduce thermal effects on the lens elements. Together, these technologies work to maintain image quality and lens reliability even during long shoots under the hot sun or artificial lighting.

Dust & Water-Resistant with Fluorine Coatings for Use in Harsh Conditions

Built to L-Series specifications, the EF 400mm f/2.8L IS III USM features a highly durable design for excellent performance in inclement weather conditions. It is dust/water-resistant, with seals around the mount, switches, rings, and more. To help maintain a clean lens after multiple lens changes in sub-optimal conditions, the EF 400mm f/2.8L IS III USM features a specially designed fluorine coating on its front and rear elements. This coating helps to prevent water, oil, and other surface residue (e.g., fingerprints) from sticking to the lens, which facilitates quick and easy cleaning without the use of solvents.

Customizable Electronic Focusing Ring

A customizable electronic manual focusing ring helps the user capture the desired shot at precisely the right moment. Three sensitivity levels are available to set how quickly and precisely the user needs to adjust focus. This is helpful when needing a slower speed to move between a subject's eyes in a distant profile, or a faster speed to concentrate on different birds in a large, swiftly moving flock. Manual focus is still available while autofocus is engaged, allowing the user to fine tune focus adjustments to suit shooting style and preference.

Up to Two Focus Presets Available

Quickly select between two points with focus presets. This feature is especially useful for fixed-position sports photography, as you can choose two exact focal distances and switch between them with a simple twist of the recall ring (e.g., if you’re on the sidelines of a soccer game, this feature allows you to rapidly transition between either team's goal for quick acquisition of important shots).

Optical Image Stabilization at up to 5 Stops* of Shake Correction

The EF 400mm f/2.8L IS III USM features an Optical Image Stabilizer system that provides shake reduction for up to 5 shutter speed stops*. This helps provide reliable handheld performance and clear image detail in low-light situations or at lower ISOs.

*NOTE: Based on CIPA (Camera & Imaging Products Association) standards; testing performed at a focal length of 200mm using the EOS-1D X Mark II digital SLR camera.

Minimum Focusing Distance

This lens features  a minimum focusing distance of approx. 8.2' (2.5m), making it easy to fill the frame with details or capture action-packed scenes for dynamic and impressive imagery.

9-Blade Circular Aperture for Beautiful Bokeh

The EF 400mm f/2.8L IS III USM features a 9-blade, circular aperture to create gorgeous, evocative out-of-focus areas and soft backgrounds. With an incredible level of control over bokeh, the 9-blade circular aperture helps the user create intimacy and intensity in photos and videos.
