Took mine out for a real world test run tonight, and was shocked that the battery gave out at about 300 shots. No flash was used. 10/20D regularly got between 500-700 with the same 300L IS mounted. 1D mkIIn's regularly click off 1000 plus. I ran around Atlanta trying to find anyone who sold spares, and no one had any. One dealer said he was not surprised they were so weak as he thought it was the same battery some of the older camcorders used. Anyway, lots of nice things about the camera, but battery life isn't one of them.
