The Canon EF 400mm f/4 DO IS USM is a great lens for sports, nature, and wildlife photographers who require big results in a relatively compact size. Designed with diffractive optics (DO), this lens benefits from a smaller size and lighter weight while still maintaining a fast aperture and super telephoto reach. It is dust and moisture resistant due to its magnesium alloy lens barrel. This lens featured two-stage image stabilization with dual-axis camera shake correction or vertical axis only for panning. An AF Stop function shuts off autofocus when an obstruction appears. There is an additional focus preset function that allows you to return to a specifically set focus by turning a ring in front of the focus ring. It is nearly silent, sporting high speed autofocusing with full-time manual focus override. Because of its full compatibility with 1.4x and 2x extenders, you have the option of added focal length versatility. This lens is boasts a lightweight design enabling it to be handled for short periods of time, lending itself to added applications such as photojournalism. It is advised, however, to be paired with either a monopod or tripod with a gimbal-type tripod head for extended use.
