7d - life of LP-E6 Cannon battery?
There are weddings that we shoot almost non-stop for 12-14 hours. In addition, we now have the ability to add guick movies with this camera. We also use use the 580ex ii flash, not the camera's internal flash.
How many canon LP-E6 batteries do you go through in 12-14 hr day of shooting? How many shots (raw only-17.9M) do you average per battery?
