The EF 400mm f/2.8L IS III USM is the world’s lightest¹ 400mm f/2.8 lens, designed to give professional sports and wildlife photographers the freedom they need on location. It’s light enough to be used handheld, and the fast f/2.8 maximum aperture with 5-stop Image Stabilizer help create brighter, sharper images even in low-light. A responsive USM AF motor keeps fast-moving objects sharp, and customisable fingertip controls allow instant AF start, AF lock or focus recall. Part of the Canon professional L-series flagship range, its designed for robust handling and resistant to dust and moisture.
