flash cams use the least batteries, but no matter what cam you will probably need another battery. for good low light you pretty much need a high def cam. if you want, you can still shoot in standard def with most high def cams.
My friend is looking for a new camcorder to take on a trip:
She is wants to spend under $700.
She will be shooting action (dancing and capoeira), maybe some low-light shots.
And she needs something where the battery will last awhile and the quality is good enough to put onto a DVD for a school.
Beyond what you would choose under these conditions, I am curious to know what would be better for battery life: a hard drive camcorder, a DV tape camcorder, or a flash based camcorder?
I would assume the flash based but I haven't worked with any besides the Pure Digital Mini cameras and those are short of the quality that she is looking for anyways.
