How many shots is the standard battery good for?
My MkIII battery if the camera is used continuously (Ie not intermittent use over several days when the natural discharge and the repeated switch on/off has some effect) is good for between 4000 and 5000 shots. Some have had over 6000 on a single charge. The official specs say 1800shots. I can't believe the 7D battery life is as officially quoted - ie I would expect 1500 shots on a charge, based on an official life of ~800. I've only taken 3000+ shots in a day a few times - so two batteries for the 7D should be enough.
Of course, I guess video/live view would kill the battery quicker, so more might be needed in that situation.
Anyway, you knew the cost of the batteries before you bought the camera didn't you? Don't like the cost of spares/accessories, get a different camera.
