(http://img2.fengniao.com/product/13/416/ceZ2A6P1Z9zgI.jpg)　　作者拍摄了标准色板，使用最大JPEG，色彩风格、锐度和降噪都为缺省值，向索尼α700的高感降噪就设置为了Normal。作者在原图的100％基础上截取了右下角部分，蓝色和黑色各占一半。

　　从上面的样张来看，α700的控噪比α100好了很多，特别是在高感下，这种差别更加明显。有趣的是，α700的画面在感光度较低时看上去比EOS 5D还要干净，不过在高感的时候，5D就表现出了一个全画幅相机应该有的表现，噪点控制更好。
　　作者声明，这只是α700工程样机的表现，至于真机的效果我们还是等到实机到达时做更详尽的评测。

我吹捧5D的控躁，是因为比D200强多了。

D80的控躁比D200更强，

700应该是和D300一个感光吧？

[outuo]

要注意这里的D80应该没有开高ISO降噪，实际效果更好。

不知道，有可能是

[outuo]

不过alpha100跟d80是同一颗CCD

如果是alpha700噪控超过40D，可以说D80的噪控超过20D跟30D
哈哈

[heavywind]

80的控躁都超过200了。
