Am I the only one having a battery life issue with the SD14? Starting with a fully charged battery, I have gotten as few as 18 shots and no more than about 75 shots before the low battery indicator begins to blink. I have had this problem with four different batteries and two different SD14 bodies. I generally shoot with AF and OS both on, and I usually remember to turn off the remote shutter function when I no longer need to use it. I have read several reviews of the SD14 where users claimed that they got anywhere from 200-300 shots from a fully charged battery. Why not me???
