Let me be clear: I love the Nikon D800. But there is something that really bugs me. And that is the battery life. I took my camera on a business trip this week. The battery ran out after 250 photos. Granted a lot of them were long exposure (5-15 seconds), but this is almost ridiculous. My D300s seemed to last for weeks.
However, the battery is on re-call. I just found out. Will call Nikon on Monday to get a replacement. I do hope that this will fix the problem. 250 photos is not enough.
