Canon 400mm lens
Photokina 2010 News - Canon enhances 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 Canon 400mm lens combines super-telephoto focal lengths, fast aperture and outstanding image quality, providing photographers with reliability and exceptional results. Succeeding the well-respected Canon 400mm f/2.8L IS USM, the new model will appeal to nature, wildlife and sports photographers. The Canon EF 400mm features a completely redesigned optical system and the latest iteration of Canonís original Image Stabilizer (IS) technology.
Canon 400mm lens
Manufactured using the very best optical components, the new Canon 400mm f/2.8L IS II USM marks a significant step forward for Canonís L-series, which is already renowned for its outstanding quality. The Canon 400mm lens features 16 elements in 12 different groups, using high performance fluorite lens elements that correct chromatic aberration to deliver high resolution and high contrast shots of the best possible quality - allowing photographers to capture images rich with edge-to-edge detail. The optical elements also feature Canonís 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.
Canon 400mm lens with Image Stabilizer technology
The Canon 400mm lens features Canonís new Image Stabilizer system, providing outstanding results when the photographer is moving around and when capturing moving subjects. A 4-stop advantage offers greater image quality during handheld shooting, allowing users to shoot at speeds up for four times slower than normally required with minimal additional blur. Operation of IS mode 2 has been improved when shooting panning motion and a new third IS mode has been added, assisting users when quickly switching between subjects by activating the IS unit only during exposure. Developed in line with Canonís philosophy for the elite L-series, the Canon 400mm f/2.8L IS II USM lens boasts a refined design that reflects their status as market-leading, benchmark lens. The Canon 400mm lens features a new design layout, with carefully-positioned controls that improve operation in everyday use. The AF stop buttons are now location-adjustable, improving ergonomics by allowing users to custom-select the position of the lens grip, where the AF stop buttons are located.
Canon 400mm Auto Focus System
The Canon 400mm super-telephoto 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.
Tripod mounts for the Canon 400mm lens
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, the Canon 400mm telephoto lens features 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 lens secure during location-based shoots. A robust weatherproof design makes the Canon 400mm lens suitable for use in extreme conditions when paired with a weatherproof Canon EOS body.
