Lean and Powerful
The EF 400mm f/2.8L IS III USM offers you the superb image quality of a Canon L series super telephoto in a new, lightweight form that makes it the world’s lightest 400mm f/2.8 lens*. A meticulous optical redesign means reduced flare and ghosting thanks to Super Spectra Coating (SSC) and Air Sphere (ASC), a shorter minimum focusing distance and additional comfort and portability.

Operation is made easy with full-time manual AF, while two focus presets to help you quickly dial in the spot you want. Combining sharp image quality with high operability, professionals and advanced photographers can take the EF 400mm f/2.8L IS III USM anywhere in order to capture masterful shots of nature, sports and beyond.

Customizable Electronic Focusing Ring
A customizable electronic manual focusing ring helps ensure you’ll get the shot that you want at the right moment. Three sensitivity levels are available to select how quick and precise you want to adjust the focus. 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, manual focus is still possible while autofocus is engaged, letting you finetune focus adjustments to suit your shooting preferences.

Up to Two Focus Presets Available
Quickly select between two points with focus presets. Especially useful for fixed-position sports photography, you can choose two exact focus distances, and with a simple twist of the recall ring, swap between them. If you’re on the sidelines of a soccer game, one focus point could be the home team’s goal, and the other point the visiting team’s goal. A twist of the recall ring will help ensure your most important photos are sharply in focus.

MTF Charts
A Modulation Transfer Function (MTF) chart measures a lens’ expected optical performance at the center of the picture area and measures repeatedly along the diagonal line, further and further toward the corners of the image. The higher a curve is shown on the chart, the better the lens is performing in the area the chart is measuring. As a curve moves from left to right, it displays the lens' results from center towards the corners.
