这个功能就是在摄像的时候，能够不断地自动对焦。不用不断按快门了。canon 5dII
应该是没有这个功能的。
不知道这个功能好用不好用。能不能像真的摄像机一样。新出的5d3和d800是不是有这
个功能。 |

都慢吧...

A57的摄像自动对焦功能基本完美。

发帖数: 331 | 4 这是dpreview上的描述: 看来是镜头的问题。不过有总比没有强。
希望新出的d800和5d3也能有这个功能。
Just like the D3100, the D5100's AF-F continuous focusing mode has to count
as a qualified success - in the samples below you can see it twitching in
and out of focus, and occasionally failing to establish the correct focus
for a second or two on what is a relatively undemanding subject. Obviously
it's better then not being able to refocus at all, but it can't match its
mirrorless competitors such as the Sony NEXs or Panasonic G series,
substantially because these have lenses specifically designed for the job. |

刚看了sony a55 的一个中文介绍。
http://www.pcpop.com/doc/0/578/578883_all.shtml
泡泡网数码相机频道9月21日 之所以称A55开创了数码拍摄的新纪元，原因是A55采用了
“半透镜”（Translucent Mirror Technology）技术，实现了足以媲美专业单反的追
焦和连拍能力。更重要的是，该技术的加入突破了单反/单电摄像的瓶颈，实现了摄像
模式下连续自动对焦，令DV的地位也遭遇威胁。
貌似半透镜可以解决这个问题。那nikon 7000， 5100, 3100 是如何如何摄像追焦呢。
