The 400mm f/2.8 is a high-end super telephoto lens with the optical and mechanical design that Canon integrates in any of its L lenses.

With a maximum aperture of f/2.8 and an excellent stabilizer, the 400mm f/2.8 L will always capture very tigh shots of any distant subjects even in low light.
In still photography, you can choose to enable stabilization only when the camera is triggered, thus avoiding any approximation when framing while ensuring pictures free of motion blur.

In video, the stabilizer will be deactivated automatically when it detects a pan, then leaving the camera operator perfect control of its composition during the entire camera move.

The USM technology provides for a fast and quiet autofocus.
