Recently I was shooting a lot for the Flash 101 (Off Camera) course I'm currently taking and failed to notice one battery had become exhausted. In class, when we reviewed my shots I noticed a black band at the bottom of my pics. It was suggested that the low battery rather than my shutter at 200 might be the culprit. My question is why didn't the MBD80 auto switch to the fresh battery in the other slot?
My experience is that the camera often decides to switch a little too late. I can hear the difference in the mirror movement as the battery is getting low, and sometimes AF is slower, so I usually switch before the camera does. I do not think there is a way to specify the charge level when the switch should happen.
