The EF 400mm f/2.8 L IS USM is a high end pro level large aperture super telephoto lens for Canon EOS SLR cameras (film & digital). The 400mm 2.8L IS is a premium lens for demanding photographers who want the best possible high magnification images.
The EF 400mm f/2.8 L IS USM is one of Canon's very best L-Series lenses. This top of the line design produces outstanding images with world class sharpness contrast and color. Delivering an f/2.8 aperture in a high quality 400mm lens up to Canon's L-Series standards requires a tremendous amount of optical engineering and material; very few lenses in the world use more glass. The lens also incorporates Canon's IS (Optical Image Stabilizer) technology to help reduce loss of image sharpness due to camera and lens movement. Even on tripod and monopods telephotos magnify the slightest movement and the IS system helps counteract the effect.
The EF 400mm f/2.8 L IS USM is one of the very best sports and action photography lenses made. The f/2.8 aperture coupled with it's very narrow 6° angle of view (diagonal) place this lens in a very select league of ultra-pro telephotos able to produce the highest magnifications with the fastest shutter speeds. The AF system is ultra fast and offers several amenities for customizing set up including a focus limit switch, focus preset/recall, AF stop button, and full time manual focus override.
The 400mm f/2.8 L IS USM is also a really remarkable portrait lens. You can select a narrow sliver of a background, compress perspective, and deliver a jaw dropping amount of background blur.
Canon introduced the EF 400mm 2.8L IS in late 1999 as a replacement for the professional favorite Canon 400mm f/2.8 L II USM. This all new design is over a pound lighter than it's predecessor even though it uses six more lens elements, incorporates Optical Image Stabilization, and focuses a meter closer. In 2011 Canon introduced a newer Canon 400mm f/2.8 L IS II that features further weight reduction, faster Image Stabilizer technology, and shorter close focus. The EF 400mm 2.8L IS remains quite popular with shooters because it's performance is simply superlative and it's less expensive than the IS II. It's one of the ultimate sports & action photography lenses ever made for Canon.
