Canon A640。500張可能太過，當有8折的話，都可拍400張。一般來說，都?一整天用。

As with all A series PowerShots, the A640 is powered by AA batteries (four). Rechargeable (NiMH) batteries are not supplied in the box, so you'll need to budget for at least one set. The good news is that battery life is superb - Canon quotes 500 shots (using the CIPA standard, LCD monitor on) from a fully charged set of NiMH cells, and up to 1500 shots if you turn the LCD off and use the viewfinder. Our experience bore this out. Impressive.
