EF 400mm f/2.8L IS II USM
Canon has enhanced its premium L-series with the launch of the new EF 400mm f/2.8L IS II USM – a high quality super-telephoto lens designed to meet the demands of professional photographers. Offering optical excellence and consistently high performance, the new lens combines a super-telephoto focal length, fast aperture and outstanding image quality, providing photographers with reliability and exceptional results.
Succeeding the EF 400mm f/2.8L IS USM, the new version will appeal to nature, wildlife and sports photographers. It features a completely redesigned optical system and the latest iteration of Canon’s original Image Stabilizer (IS) technology. An all-new magnesium alloy construction and titanium components ensure the design is both robust and lightweight. The EF 400mm f/2.8L IS II USM is the lightest lens in its class (as of August 2010) offering unrivalled mobility due to a 28% reduction in weight (1.5KG) compared to its predecessor.
Ultra high performance optics
The optical elements also feature Canon’s latest Super Spectra Coatings, optimised for both the position and type of each lens element. A SubWavelength Structure Coating (SWC), which uses microscopic cone-shaped structures smaller than a wavelength of visible light, reduces ghosting caused by light bouncing back from the imaging sensor. Fluorine coating is also used on the front and rear elements of the lens, repelling dust and dirt for clearer shots. The coating is also water repellent, keeping the front element free of water marks and smearing by ensuring water runs off the lens quickly.
New, improved IS and rapid AF
The lens offers a constant f/2.8 aperture, allowing photographers to shoot at faster shutter speeds and capture clear shots of fast-moving subjects. The wide aperture also allows users to creatively isolate their subjects from the background, with a nine-blade circular iris creating dramatic and striking background blur that instantly adds beauty to an image.
Fast, quiet Auto Focusing (AF) is provided by a ring-type USM, new dedicated AF algorithms and a new high-speed CPU, which offer quick and accurate focusing during shooting. Photographers can also utilise full-time manual focusing functionality, which enables the adjustment and fine-tuning of focus even when the AF system is activated, providing even greater control over image capture. A new Power Focus mode aids focusing during video shooting, allowing the photographer to smoothly adjust focus during filming by twisting the focus recall ring.
All-new premium L-series design
A choice of dedicated tripod mounts provides added flexibility, allowing photographers to use a long or short foot suitable for monopods or tripods. A new rotational mechanism for the tripod collar also provides a smoother movement when turning the lens from portrait to landscape orientation. In addition, both models feature a new high quality exterior texture, while a new shade of white casing indicates the new advanced design and higher precision that the lens offers. A new Kensington-type wire security lock has also been added, allowing photographers to keep their lenses secure during location-based shoots.
A robust weatherproof design makes the lens suitable for use in extreme conditions when paired with a weatherproof EOS body.
