300焦距2.8跟4差一档差的还是蛮大的……
600这个段想做到2.8技术难以实施

真出了 价格不虚高就入 不过估计至少一年

这两个也没啥关联啊，看对手应该是最好的办法，估计24-70修改提升一下是可能的，is感觉才不会这么傻搞出来呢。

这个逻辑还挺新颖的
我一直以为200-400是拿来跟328比的。。。

Canon has released a successor to its professional workhorse fast telezoom, in the shape of the EF 70-200mm F2.8 L IS II USM. Although outwardly similar to its predecessor, the new lens features a revised optical design, incorporating a fluorite element and no fewer than 5 UD elements for the correction of chromatic aberrations. The minimum focus distance has been reduced to 1.2m, with a corresponding increase in maximum magnification to 0.21x. The mechanical design has also been modified, with the most obvious external change being a wider focusing ring. As usual for an L series design, the lens features dust- and drip-proof construction. It's also fully compatible with Canon's existing teleconverters and extension tubes.
5th January 2010 – Canon today adds to its acclaimed L-series with the launch of the new EF 70-200mm f/2.8L IS II USM telephoto zoom lens. The lens launches as the successor to the immensely popular EF 70-200mm f/2.8L IS USM, offering improved performance in every area.

True to the L-series’ heritage, the EF 70-200mm f/2.8L IS II USM delivers optical excellence in the most challenging situations. As well as a revamp of the internal optical system, the lens has also been structurally re-developed as a direct result of user feedback, making it as robust and reliable as it is optically advanced.

“Reuters’ photographers have used the EF 70-200mm f/2.8L IS USM for a number of years and it allows photographers a great level of flexibility,” said Reuters Production Editor Kevin Coombs. “The focal length, fast aperture and Image Stabilizer all contribute to it being a workhorse lens and you’ll find it in many professional photographers’ camera bags. I’m very much looking forward to seeing the improvements offered by the EF 70-200mm f/2.8L IS II USM.”

Premium quality, premium performance

The EF 70-200mm f/2.8L IS II USM features a re-designed optical system, consisting of 23 elements in 19 groups to deliver truly impressive results. A high-performance fluorite element is used at the heart of the lens path, coupled with no fewer than five ultra-low dispersion (UD) elements, drastically reducing chromatic aberration throughout the zoom range to produce high contrast images with edge-to-edge definition.

A high-speed Auto Focus (AF) system perfectly matches the abilities of the recently-launched EOS-1D Mark IV and EOS 7D Digital SLR (DSLR) cameras. The new model also features a ring-type USM AF motor, which combines with a new high-speed CPU and an optimised AF algorithm to make auto focusing both faster and quieter.

A reduced minimum focusing distance of 1.2 metres (3.9 ft) and improved 0.21x magnification will allow photographers to get closer to subjects without needing to swap lenses – greatly benefitting time-pressured news and events photographers who require flexibility. An updated Image Stabilizer mechanism also offers a shutter speed advantage equivalent to four-stops, reducing the effect of image blur resulting from camera shake in busy shooting environments.

Enhanced design, exceptional ease of use

As well as an update to the internal construction, the EF 70-200mm f/2.8L IS II USM features an enhanced external appearance to improve lens operation. The thickness of protruding exterior parts and switches has been significantly reduced, guarding against accidental switching and creating an improved overall look. The rubber focusing grip has also been redesigned and widened; with finely-patterned grooves making it easier to manually focus.

Being an L-series lens, the EF 70-200mm f/2.8L IS II USM is fully weatherproof, making it ideal for use in all weather conditions. The mount, focus mode switch and focusing ring all feature a completely dust and drip-proof structure, preventing dust or water from getting inside the camera and lens when used with accompanying weatherproof EOS bodies. The lens has been designed to stand up to the daily wear and tear of professional usage, making it a highly durable, reliable lens for use day-to-day by professional photographers.

High quality L-series accessories

The EF 70-200mm f/2.8L IS II USM is supplied with several accessories, including the new ET-87 Lens Hood and the Ring-Type Tripod Collar B (W). A brand new Lens Case LZ1326 is also included as standard, offering quick and easy access when users need to switch lenses in time-pressured situations.

Compatibility with a range of optional Canon accessories also allows users to pair the EF 70-200mm f/2.8L IS II USM with the Lens Extender EF 1.4x II, Lens Extender EF 2x II, Extension Tube EF 12 II, Extension Tube EF 25 II, and 77mm filters.

大炮做到4求的是轻便
所以200 400是个有技术不符合实用的玩意
一炮顶仨，确实，200 400一炮差不多顶C228 340IS 456IS的重量之和，价钱之和还多

我到希望24-70L的头改善镜片把2.8的锐度不够这个缺点改进。。让这个头更完美。。

- -这样的话估计那堆红圈定焦是没指望更新了~消费市场上没什么对手~

等2470，情绪稳定

但是很值得。

N200-400价格超贵。。。

真的？

啥都敢说啊，真不怕风大扇了舌头

小白终于用上萤石镜片了。

又得贵好几千了

尼康早就是4剑客了，14－24 24－70 70－200 200－400，超希望佳能出一个200－400。

据说佳能图谋把变焦三剑客变成四剑客，真是够奸

看娱乐圈三人组合最后还是比四人组合红哦

我现在深信你是ｃ的推手，尽管方式比较另类。

24-70 2.8俺早已经见过试用镜了，但70-200先发不知道为啥，一定是战略问题

真棒，期待中

吼吼~这个东西不知道什么时候上市啊

佳能的策略是后发制人，别人不动，他打死不动。

希望如此
