嗯…我看中了Sanyo Xacti VPC-J4…
但又不知道到底好不好用……
同埋抵唔抵買……

各位高手可唔可以俾d意見我喔?
我係新手黎架咋……

我有J1，3m pixels，開機快，對焦速度都算係咁，shutter lag小。存相睇相都快，Playback可放大到45倍咁誇，影得好唔好可以即時知道，good！加上拍到640x480@30fps，短片拍得住DV，隨身袋，snapshot一流。

J4有4m的pixels，mpeg4短片(壓縮比例高，但質素唔及motion jpeg)，其餘和J1J2分別唔大！

As I know J4 also use motion Jpeg, not Mpeg4.

I have an interesting comparison on Mpeg4 and Motion Jpeg:
I have downloaded a video from a website. They provide 2 versions: One is 320X240 Motion Jpeg and the other is 640X480 Mpeg4. The file sizes are about the same. It seems that the Mpeg4 wins as the resolution is 640X480 in a similar file size, but in fact, when you enlarge the 320X240 motion Jpeg to the size of 640X480, you will get a very similar picture quality.

Thanks for the correction! Maybe I get confused of the 770!
