闪光灯同步变为1/300秒，iso可扩展到6400
其他的一些翻译：
1）See the Whole Picture with a Live View LCD
One of the landmark functions of the EOS-1D Mark III Digital SLR is the introduction of a Live View shooting mode, tweaked to meet the needs of professional shooters. Photographers who use point-and-shoot digital cameras are familiar with looking at the LCD screen on the back of the camera to compose their images. Normally, a single lens reflex cannot do this because the mirror that lets you look through the lens is in the way.

翻译一下： 1D MARK3其中一个里程碑式的功能是拍摄实时预览模式。那些用DC的摄影师对液晶取景都很熟悉。正常来说，SLR的反光镜构造不能实现这种功能。 1D MARK3 的出现令摄影师在取景上有更多的选择。利用全新的“LICE VIEW SHOOTING”模式，您手上的DSLR能在3寸的液晶上完成对焦和构图，并能把图象放大5倍和10倍，以达到理想对焦。如果用户在相机几米以外（离机拍摄），例如在影室，相机能用USB2.0连到电脑。
如果摄影师离相机很远，例如在体育馆里的另一头，或者摄影师因为某些原因不能碰触到相机，1D MARK3可以用新的“WFT-E2A”无线文件传输模块进行远程操作。………………
作为附带的好处，“LIVE VIEW”拍摄模式能减少低速快门由于反光镜震动带来的影响，因此可以提高图象质量。 （不就是反光板预升取景嘛，说的真玄乎，还没E330的两个CCD革新。估计这种模式巨费电，而且长时间用肯定增加噪点）
（2） “Major advances have also been made in recording, storage, and playback. For example, in addition to the RAW and JPEG options found in previous EOS Digital SLRs, the EOS-1D Mark III Digital SLR now offers the “sRAW” recording format. “sRAW” has all the flexibility of standard RAW data recording, but at one quarter the resolution and approximately half the file size of conventional RAW images. ”
启用一种新的RAW模式，叫做“SRAW”，这种模式有RAW所有的易用性，但只有1 /4的分辨率（不知道啥意思），和原始RAW一半的大小。（1千万象素变250万，大小才降了一半，岂不是亏大了）
（3）“Speedlite 580EX II Flash
The popular Speedlite 580EX Flash is being replaced by the new Speedlite 580EX II Flash, which features a host of improvements, including a metal hot shoe with an improved locking mechanism for added durability, an external metering sensor for non-TTL automatic flash exposure control and a PC socket for use with non-dedicated slave triggers. Fully compatible with all EOS SLRs, the new Speedlite 580EX II is gasketed for dust and moisture resistance, making it possible for users of EOS-1 class digital SLRs and many L-series EF lenses to use flash safely when shooting in dusty or wet environments.”
16-35L的改进好像没什么特别，倒是二代580有点意思，翻译一下：
2代580有很多进步，包括改进的灯脚锁，为非TTL自动闪光设计的感光器和一个无线引闪的闪光灯座。 和全部单反都能配合良好，2代580防水防滴，使得EOS1系列相机和很多L镜头配合2代580在恶劣环境下能正常工作。
（4）“brand-new autofocus system in the EOS-1D Mark III Digital SLR represents a complete reconsideration of professional AF. Like previous EOS 1-Series Canon cameras, the EOS-1D Mark III Digital SLR has 45 AF points, but unlike its predecessors, 19 of them, rather than seven, are of the high-precision cross-type configuration”
像前一代的1系列相机，MARK3有45个焦点，但是其中的19个焦点，而不是以前的7个，是高精确十字对焦！！
