My battery died on my camera, that annoying red blinking light in the viewfinder, never a good thing when your in the middle of photographing a live action subject. I popped out that battery and watched in horror as I reached for a fully charged one, it was Tommy doing a cartwheel, 3 full somersaults and a synchronized swimming routine that would make any professional proud. I popped that fresh battery in, clicked the on switch and aimed that 400mm right at him; he was back to suntanning. I think only other nature photographers are going to actually get this.
