The EF 400mm f/5.6 L USM is a professional quality fixed focal length telephoto lens for Canon EOS SLR cameras of all sorts (both film and digital).&nsbp; The 400mm f/5.6L is part of Canon's L-Series top level class of gear. With a narrow 6°10' angle of view delivering lots of magnification it's a lens well suited for outdoor wildlife or action photography such as large field sports
The classic optical design delivers superb results thanks to a design unburdened by the compromises inherent in zoom lenses, wise use of high grade optical materials (including a Super UD, a UD glass element, and excellent coatings), and excellent craftsmanship. Built solidly to take a lot of use the 400mm f/5.6L has a metal housing and removable rotating tripod collar. The built-in retractable lens hood is seriously convenient being both quick to deploy and stow.
The lenses uses a USM (UltraSonic Motor) to produce fast and quiet autofocus. The inner focus mechanism also allows full time manual focus override when needed. A focus range limit switch allows the choice of the full 3.5m-∞ focus range or a narrower 8.5m-∞ focus range which reduces AF seek time.
Originally released in 1993 the 400mm f/5.6L has been in Canon's line-up ever since. Newer zoom options like the 100-400mm L have been released but the 400mm f/5.6 is noticeable lighter and less expensive so it remains popular with users seeking high quality telephoto images who don't want/need less magnification
