這裡有一篇關於DP1速度不太行的評比：

All these small digicams are slow, but I found the DP-1 to be the most unresponsive camera I have ever handled. When you half-press the shutter button, it locks the focus. Unfortunately, it also locks the screen for about a second when focusing. A person can move right across the screen while the camera is focusing and the screen shows a still image for all that time!
