Canon EF 600mm f/4L IS II USMСлед двете нови светкавици от Canon пуснаха и два нови обектива. Това са Canon EF 500mm f/4L IS II USM и Canon EF 600mm f/4L IS II USM. И двата обектива са с напълно преработена оптика, с 16 елемента в 12 групи. Всеки от тях е с имплеметирана фирмената технология Canon Image Stabiliser (IS). Конструкцията им от магнезиева сплав с титаниеви компоненти прави и двата обектива значимо по-леки и по-здрави от техните предшественици. Бързият и тих автофокус се осигурява от кръгов ултразвуков мотор (USM). И двата обектива са водозащитени и ще бъдат налични на пазара в средата на 2011 година.

Canon EF 500mm f/4L IS II USM ще бъде на цена £8,999/€10,799/$9,499, докато Canon EF 600mm F/4L IS II USM ще се продава срещу £11,299/ €13,549/$11,999...

Canon Press Release

Benchmark performance, superior design – Canon launches the lightweight, super-telephoto EF 500mm f/4L IS II USM and EF 600mm f/4L IS II USM lenses

United Kingdom, Republic of Ireland, 7th February 2011 – Canon today launches two new super-telephoto lenses for its leading EOS Digital SLR (DSLR) range – the EF 500mm f/4L IS II USM and the EF 600mm f/4L IS II USM. Designed to meet the needs of the most demanding sports and wildlife photographers, both lenses offer breakthrough performance, delivering consistently high-quality images and incredible mobility. The launch of the models follows a development announcement in August 2010, and the display of prototypes at Photokina 2010 in Cologne, Germany.

Launching into Canon’s professional L-series, the models replace the widely-respected EF 500mm f/4L IS USM and EF 600mm f/4L IS USM, and are designed to achieve unparalleled levels of image quality. Each 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 market research conducted 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, while the EF 500mm f/4L IS II USM offers an impressive reduction of 17% (680g).

New levels of performance
Both lenses feature 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 in these lenses– delivering high resolution, high contrast shots rich in detail across the frame.

Both lens’ 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
Both models feature 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.

Both lenses offer a constant f/4 aperture, 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
Both lenses have been designed as part of Canon’s renowned elite L-series, combining exceptional-quality optics with stylish designs. Both also feature 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 lenses secure during location-based shoots. The robust design is also weatherproof, making both lenses suitable for use in extreme conditions when paired with a weatherproof EOS body.

Pricing and Availability
The EF 500mm f/4L IS II USM is available from mid 2011, priced at £8,999.00/€10,799.00 RRP incl. VAT.
The EF 600mm f/4L IS II USM is available from mid 2011, priced at £11,299.00/ €13,549.00 RRP incl. VAT.
