I'd also recommend the Pentax K5 and it's more recent incarnations, the K5II or K5IIs (which lacks an AA filter). They're a very well featured, well built, reliable, water, dust and cold resistant, small DSLR. They're rated to -10C. Pentax's lens range is well suited to the outdoor photographer (in the sense that you can buy some excellent small light primes). The range caters for most needs, but they don't offer TS lenses or have the range of options that C&N do in very long lenses.

Suggest you read the DPR review.

Cheers, Rod

The ratings don't really mean anything in terms of actual performance, just how much liability that their lawyers are prepared to accept. In the past, the commercial temperature range for electronic components was quoted a 0-70C, which means that the manufacturers wouldn't have a claim against the component suppliers if the component failed being used outside that range, so, 0-70C has become the default warranty range for most electronic equipment (usually cut at the top end to allow for imperfect cooling, etc). More recently, with the change from bipolar to CMOS technologies, the range has got higher, -40-85C being typical - nonetheless it only takes one component to have a 0 limit to limit the whole thing. What is more likely to cause a low temperature limit is freezing of lubricants, and you have no information in which lubricants have been used or what is their limit.
