I've used my D200 in colder temps. While I have no complaints normally
of battery life, it does drop quickly at cold temps . Best to ahve
another in your pocket. Once the battery is warmed up you get some
more shots from the battery that was near 0 charge at 10 degrees F.
Haven't had any problems with the auto focus.

Chances are pretty good the problem was the lense instead of the
camera. It's worth trying a different lense to find out.
It is also possible that a brand new camera or lense might be a
little tight... and that after a bit of use it will loosen up.
For cold weather operation that is significant. Hence, next
winter it may work a lot better!
Regardless, the real trick is to figure out how to keep the
camera warmer. That can be tough when skiing or doing something
else that causes a lot of perspiration. Keeping the camera
under a coat works well, but if you are working and sweating it
should be inside a plastic bag too.

I was using my D100 this past weekend at -30C. Didn't have any problems
with it.

Which lens? Was it one of the older ones with the "screwdriver
drive" for the autofocus, or a newer one with the ultrasonic motor built
into the lens? I would expect the latter to work a bit better at low
temperatures -- but it may depend on the grease used in the mechanism.

Keep a spare battery warm in an inside pocket -- and the camera
warm by putting it under the coat (if possible).
Check the mechanical behavior of the lens' focus mechanism when
it is that cold. (Switch the camera body to manual, and see whether it
is more difficult to turn the focus ring.) If it is more difficult, you
may have to take the lens to a pro shop and get it re-lubed for low
temperature operation.

You don't say whether you were using the same lens in both
cases. If so, it may be that the limitation is in the lens, not the
camera body.
Good Luck,
DoN.

Don,
For me, the trick must be to keep a camera out of extreme climates, and quick changes in temperature. That may be very hard to do skiing!
In Antarctica, I momentarily took my camera out of a plastic bag from under my coat when taking a photo, and would immediately return the camera to the plastic bag next to my body heat under my insulated coat. I suppose a pro would have better ways of coping with quick/extreme changes.
In very hot climates in Africa, while traveling in an air conditioned bus, I would follow the same process of putting the camera in a plastic bag before entering the cool air inside the airconditioned bus. Otherwise, I would get dropplets of water on my lens with the temperature changes.
At the present time, I use a Nikon D200 most of the time, but have not used it in extreme climates. I still think about temperature changes even in the DC area when going outside in freezing air from a warm 70 degrees inside the house.
