想买数码单反了。去 rayi.cn 上看看价格，发现 EOS300D、20D 价格又比年初下落了600-1000元。

1、佳能EOS300D机身：5360元。单机＋手柄：6200元。
2、佳能EOS300D套机：6090元。套机＋手柄：6950元。
3、佳能EOS20D机身：11200元。机身＋手柄：12500元。
4、佳能EOS20D套机：11900元。套机＋手柄：13200元。

再查，350D 机身现价 7230元，黑色。买了它上半年的日子就不好过了。但现在又有挺强列的想买的欲望。

（上述产品皆为日货）

【摄影玩玩】一个扭曲照片的分析

没脾气2x — 2004-12-07 15:46:00Z

如图：

人走路的速度以时速 4km/h ～ 5km/h 计算 1.11m/s ～ 1.39m/s

一般相机从机械上来说大多只有 1/125 的快门。
快于 1/125 的快门是靠 1/125 的快门双幕帘移动模拟的.

设人的速度为 1.2m/s 人在 1/125 秒大该走 0.9cm。
0.9cm 应该不可能形成这么夸张的扭曲。除非他的机械快门跟本就没法这么快。

这张照片，在拍摄一瞬间，人大概移动了15-20cm（看上去大概10cm，照片的一半）。
以15cm计算， 1/125 * 15cm / 0.9cm 约等于 1/7.5

也就是说这个相机的机械快门速度大概是 1/7.5。

……据说这个照片是用爱普泰克网易拍拍的。

当然，如果这照片是ps出来的，我上面分析的全是放屁。
