We are on a quest to find a great, easy to hike with digital camera that likes the cold and can handle negative temps. Often when I take pictures to document our treks, I find my camera's batter power has been sapped. On two separate occasions when the battery lost power it wiped out the memory card with it. They were amazing pictures too... My husband is also venturing to summit Denali this spring and the last thing we want to have happen is for him to summit and not to have the pictures to prove such a once in a lifetime feat. We are seeking suggestions. Please leave a recommendation in the comment section if you have info that will help us.
