I'm living in Finland,in very could area. Is there any differences in camera use and operations between CCD and CMOS sensors, if you have a temperature from -15C- -35C.
Everybody knows battery probloms and so .

This thread beats the "cold" issue to death. No comments on CMOS vs CCD from what I read, just tips on how to handle cold
Below is some info form post 25
There has been a lot of stuff in this thread by people who are theorising and there has been a lot of pseudo science about pressure etc.
It is primarily the cold and not the pressure that will affect the camera in terms of:
- reduced power from batteries (consider keeping them in your clothing to keep them warm)
- increased viscosity (stiffness) of lubricants (affects aperture leaves the most)
- possible LCD problems (dont really need it)
- condensation and icing (most serious problem)
- memory card problems
My suggestions are to keep the camera at ambient temperature, i.e. in your pack and the battery/s in your jacket. A spare battery is a good idea and so is a high performance memory card. Definitely avoid pulling a warm humid camera out of your clothing into sub zero temps. All the moisture will instantly ice up the optics and it will stay that way. So the camera must stay close to ambient temperature all the way up so as to gradually equalise the internal/external humidity.
On the subject of altitude effects, if you haven't been above 5000m before then I would not advise attempting Aconcagua as your first big mountain but it sounds like you have done a bit more climbing than I have. Acclimatisation and a very solid, longstanding base of fitness are good assets for high altitude.
I am planning to try Aconcagua sometime in the next few years after gaining a bit more alpine experience first and I will not hesitate to take a DSLR when I do.
Good luck and stay focused
