A:Answer I have found these batteries to last a good long time. I can go out nature walking for the better part of the day, and come home with hundreds of shots from macros to landscapes to 30x zoom and still have battery left. Of course, videos and lots of zooming can wear a battery down faster than standard shots.
I think this would be an awesome unit to take on vacation, but I would never leave home without an extra battery & SD card!! Not even when I go for a nature walk :)
