I've had my camera out in all kinds of conditions: sun, cold, snow, rain. Earlier this week I was out shooting some urban stuff for several hours while the temp hovered around 0. I've only run into two problems... condensation that occurs when I go from warm to cold environments and rain. Rain and really wet snow shut my camera down for three days while it dried out. Snow (if falling well below freezing) tends not to be a problem. I just wipe or blow it off. And yes, cold weather kills your batts much faster.
