i find it costly every time i need to buy batteries. somemore
eventhough they are still 3/4 full, they cannot be use liao as the
camera needs more power, especially for flash.
rechargable batteries takes a long time to charge. and if not use
for a period of time, will slowly lose it power.
i prefer Lithium Ion myself. if need to use the camera, just
remember to charge it 1 day in advance.
