I was in Death Valley this morning. Got up to take some sunrise pictures and could not navigate any of my menus to change settings, no response from the multi-selector pad. It was only in the low 30's, so don't think it was the cold. Luckily, I had the settings I wanted and was able to take some pictures, but if I had been taking star pictures the night before, many of my settings would have need to be changed. I'm home now and everything is ok, but I certainly don't want that to happen again. I make a lot of changes during the day.
