A few months ago I posted asking about digital verses film for a backpacking trip in the Rockies in Feb. I have two options right now. I have a Pentax K100 and a Canon Rebel Xs. The Rebel fits my canon EOS lenses that I have which means I have nice glass for that camera. The Pentax only has a 50mm stock lens so if I use that one I need to get some other lenses. The Rebel Xs of course has more battery operated parts. But that means auto focus and a better metering system. Anyone have experience with a film SLR like the rebel in cold weather? How do the batteries hold up? Does the digital info screen have any problems?
