Overview

The Canon EF 400mm ƒ/5.6 L USM Photography Lens with EF-Mount is a super-telephoto prime covering Full Frame sensors. Super-telephoto focal lengths reach subjects that cannot be approached, the working range of wildlife and field sports. A ƒ/5.6 maximum aperture suits well-lit work and subjects that want more depth of field, closing to ƒ/32. Autofocus lets the camera's own subject detection drive the lens, which is what makes it usable for tracking moving subjects and for video. It mounts via EF-Mount. Closest focus is 11.5 ft, for a maximum magnification of 1:8.3.

Key Features

Super Telephoto Full Frame Coverage

The lens covers Full Frame sensors. A super-telephoto field of view reaches subjects far outside the action, which wildlife and field sports depend on.

ƒ/5.6 Maximum Aperture

ƒ/5.6 is a moderate maximum aperture, suited to well-lit conditions and to work that wants deeper depth of field, such as landscape and product photography. It closes to ƒ/32.

Autofocus

The lens focuses under the camera's control, so hybrid shooters can use the body's own subject detection and tracking rather than pulling focus by hand — the difference between catching a moving subject and losing it.

1:8.3 Maximum Magnification

A maximum magnification of 1:8.3 sets how large a small subject renders on the sensor, with a closest focus of 11.5 ft.

Mount & Build

EF-Mount

The lens mounts via EF-Mount, which sets the bodies it fits directly and those it reaches through an adapter.

Electronic Lens Communication

Contacts in the mount pass aperture, focus and focal length between lens and body, so exposure data is recorded to EXIF and in-camera corrections for distortion and vignetting apply automatically.
