EF 600mm f4L IS II USM
from Canon information February 2011
Canon launches a new super-telephoto lens for its leading EOS Digital SLR (DSLR) range – the EF 600mm F/4L IS II USM. Designed to meet the needs of the most demanding sports and wildlife photographers, the lens offers breakthrough performance, delivering consistently high-quality images and incredible mobility. The launch of the lens follows a development announcement in August 2010, and the display of a prototype at Photokina 2010 in Cologne, Germany.
Launching into Canon’s professional L-series, the model replaces the widely-respected EF 600mm F/4L IS USM and is designed to achieve unparalleled levels of image quality. The lens includes the highest-quality optics and the latest Canon Image Stabilizer (IS) technology, while magnesium alloy constructions with titanium components make each lens significantly lighter and even more durable. Launching as the lightest lens in its class (according to Canon research in December 2010), the EF 600mm F/4L IS II USM benefits from an exceptional 27% reduction (1.4kg) in weight compared to its predecessor.
New levels of performance
The lens features completely redesigned optics, with 16 elements in 12 groups. Canon has over 40 years of experience in the manufacturing of fluorite lens elements, and has utilised two high performance fluorite elements – delivering high resolution, high contrast shots rich in detail across the frame.
Optical elements feature Canon’s Super Spectra Coatings and a SubWavelength Structure Coating (SWC), optimised to effectively reduce ghosting and flare. A water-repellent fluorine coating is also used on the surface of the front and rear elements, repelling dust and dirt for clearer shots, and keeping the front element free of marks by ensuring water droplets run off the lens quickly.
Enhanced IS, precise AF
The lens features Canon’s latest Image Stabilizer system, offering outstanding image quality during handheld shooting and allowing users to shoot at speeds up to four times slower than normally required. IS Mode 2 features new algorithms to improve performance when panning, and the new IS Mode 3 is also included, assisting users when switching between subjects by activating the IS unit only during exposure.
A constant f/4 aperture is given, allowing photographers to achieve excellent image quality in low light and capture clear, sharp 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 beautiful background blur that instantly adds atmosphere to an image.
Rapid, quiet Auto Focus (AF) is provided by a ring-type Ultrasonic Motor (USM). Photographers can also utilise full-time manual focusing functionality, which enables the fine-tuning of focus even when the AF system is activated, providing even greater control over image capture. Power Focus mode also assists users during video shooting, allowing the photographer to smoothly adjust focus during filming by twisting the focus recall ring.
Premium L-series design
The lens has been designed as part of Canon’s renowned elite L-series, combining exceptional-quality optics with stylish designs. It features a revised layout, with carefully-positioned controls that improve everyday operation. 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.
Mechanical improvements include optional long or short foot tripod mounts suitable for monopods or tripods. An improved tripod collar rotational mechanism provides a smoother movement when turning the lens from portrait to landscape orientation, and a Kensington-type wire security lock has also been included, keeping the lens secure during location-based shoots. The robust design is also weatherproof, making the lens suitable for use in extreme conditions when paired with a weatherproof EOS body.
