All good info to know. I hadn't thought about the gears in the auto-focus or battery life. I had a Canon S1 IS, an S5 IS, and a Powershot A650 and I'm sure I took one or all of them outside in the cold (probably in the 30 degree range). I now have a Canon T3i dSLR and was starting to worry about cold temps. I guess I'm a little anxious since it is new and don't want to ruin it.
Thanks All!
