EF24-70 f/2.8L II Announced
Finally Announced! London, UK, 7th February 2012 – Canon today adds to its world-famous EF lens series with the launch of three new lenses for photography professionals and enthusiasts. The new EF 24-70mm f/2.8L II USM professional zoom lens is an update to the popular EF 24-70mm f/2.8L USM, while the new EF 24mm f/2.8 IS USM and EF 28mm f/2.8 IS USM are the world’s first1 wide-angle prime lenses to feature optical Image Stabilizer (IS) technology. All three provide the highest levels of performance for modern digital photographers, combining premium image quality with durable, userfriendly designs. EF 24-70mm f/2.8L II USM: the ultra-high performance standard zoom The new EF 24-70mm f/2.8L II USM features completely redesigned optics to provide outstanding clarity, image quality and durability. A compact design makes it ideal for carrying on every shoot, and a range of optical enhancements provide improved performance – capturing greater detail across the frame while reducing distortion throughout the entire zoom range, particularly at the maximum 70mm focal length. With a redesigned optical system that includes two Ultra-low Dispersion (UD) and one Super UD aspheric elements to minimise chromatic aberration and colour blurring, the lens delivers consistently sharp, high-contrast images. Each lens element also features Canon’s optimised Super Spectra coatings to reduce ghosting and flare and ensure excellent colour balance. Additionally, a fluorine coating minimises the amount of dust, dirt and fingerprints that adhere to the front and rear of the lens, helping to maintain superior image quality. The EF 24-70mm f/2.8L II USM also enables photographers to capture their subjects up close, with a minimum focusing distance of 0.38m at all focal lengths throughout the zoom range. A ring-type Ultrasonic Motor (USM) works in combination with a highperformance CPU and advanced AF algorithms to ensure accurate, silent and ultraresponsive autofocus. For those who prefer to maintain full control in every shot, fulltime manual focusing allows photographers to precisely tweak or alter the focus of their shot at any time, even when AF is engaged. Distinguished L-series design The EF 24-70mm f/2.8L II USM is the latest lens from the elite L-series to offer Canon’s high-grade and user-focused design enhancements. The mechanical structure of the lens has been improved to offer enhanced zoom durability and greater shake and shock resistance within the lens barrel. The size of the lens has also been reduced by 10mm compared to the previous model, providing enhanced portability and greater convenience in everyday use. A new Zoom Lock lever also enables photographers to lock the zoom position at the extreme wide end to prevent damage to the lens in transit, while a water and dustproof construction2 enables users to continue shooting in harsh conditions. Available April 2012 EF 24-70mm f/2.8L II USM $2299 Available June 2012 EF 24mm f/2.8 IS USM $849 EF 28mm f/2.8 IS USM $799

新24-70终于内对焦啦.锐度不详.微距没变. 价格一个黑就别提了 而且,滤镜升级到了82MM.不但所有滤镜都要升级到82MM,而且17-40 F4也留不住了,的上16-35 II才能保持滤镜的通用性.否则就带两套滤镜? 佳能逼着大伙全向82MM口径靠拢,82MM的所有东西都要贵一大截啊! 太TMD的黑啦!不但是抢钱,简直是要逼着去抢银行啊! |

我比较支持口径变大,哪怕花更多钱上滤镜 氟涂层也使得裸镜成为可能 口径变大是改善周边成像的最有效的捷径 比特殊镜片管用,设计能力弱些的死马常常用到这个办法 同时锐度改善也很明显 我们常看到死马新镜的评测往往在锐度一个指标上强过原厂.死马的5014 8514 2470都如此,价格还亲民. 原厂终于注视到这个问题了,而且还成为涨价的理由 这个价格估计能收的只有老兵了 款! |
