Hi,
I am doing the denali west buttress route 2011 june. I have a Nikon D300 which i plan to take along with a Canon S90 with extra batteries and memory cards.I am a bit nutty about photography and am willing to carry this extra load on top of the 100 odd pounds.I am curious about the effects of high altitude and cold temperatures on these cameras,lenses,batteries,memory cards and what care needs to be taken.
I have never been this high ,my highest being mount whitney and wanted to know how easy or difficult is to handle these cameras above 17000 feet? All advice appreaciated.
