Canon EF 400mm f/2.8L IS III USM Lens

EF Mount Telephoto Lens

Pairing a favoured super telephoto focal length with a bright f/2.8 maximum aperture, the EF 400mm f/2.8L IS III USM is a Canon L-series optic well-suited for outdoor, wildlife, and sports applications. This version III of this prized lens features a lighter weight design along with a sophisticated optical layout and updated handling capabilities. The fast maximum aperture enables extensive control over depth of field for isolating subjects using selective focus, and it also benefits working in difficult lighting conditions. Both Super UD and fluorite elements are used in the optical design to help reduce colour fringing and chromatic aberrations for high clarity and colour accuracy and a Super Spectra and Air Sphere Coatings have been applied to individual elements to suppress flare and ghosting for increased contrast and colour neutrality when working in backlit conditions.

Beyond the optical attributes, this 400mm f/2.8 is also characterised by its advanced five stop-effective Image Stabiliser system, which has three separate stabilisation modes to suit various shooting applications. Also complementing handling is a sophisticated ring-type USM, which provides quick, quiet, and accurate autofocus performance along with full-time manual focus override. A customisable electronic focusing ring further contributes to precise manual focus control, by affording three focusing sensitivity levels for different applications. Additionally, this lens is weather-sealed for use in trying environmental conditions and it has a removable rotating tripod collar to benefit working atop a tripod or monopod.
