In Feb 2009, I had two bodies with me : 5D MkII and 1D Mk III using the 24-105mm and 70-200mm f/4 IS. Both cameras performed well in the wet snow for 3 days and never died on me. I just kept wiping the camera dry whenever I had the chance. The other 7 days had perfect weather.

I think the 5D Mk III would be a better camera if you can afford and would perform better in higher ISO range if the weather is dull and raining snow.
