Praise the Lord, ths ski season is fast approaching. I am hoping to get out shooting this winter, get some powder shots and some snowpark action and I was wondering about the associated health risks to my beloved camera. Sitting in my backpack at - 20 celcius all day. I've heard that below freezing is actually good for the film but i was wondering more about the fine mechanics of the camera, i.e the autofocus motor and stuff like that. Will she survive?
