Dead battery! Yargh!
Like others I always carry a second battery, but in cold environments they tend to go temporarily dead and often the spare then is also dead :/
What frustrated me the other day was I set up a long exposure 20 minutes, walked away sat in my car for that time then came back to discover the shutter had closed early but I have no idea when it died.. :/
