Welcometo the world of NiMH, or even worse, Li-Ion....
No high-end digicam will keep working way below zero, since all have 
NiMH- or Li-Ion-packs....
All this even apart from the question whether the image sensor (whether 
CCD or CMOS) will keep working.

For an impression of how much worse NiMH is in cold than NiCd, see 
the last alinea's on an EOS-battery chapter in general (involving the 
1V, since the same problem applies to its NiMH booster pack):

A possible solution would be retrofitting such a digicam with NiCd 
cells, but that requires quite a bit of homebrew tinkering....
(and possibly problems with charger-incompatibilities; although 
the other way around would be worse (NiCd->NiMH))

So, if you ever hear someone say that there is no need for analog
camera's anymore, send them up a mountain in mid-winter, and see them
cry, as their camera fails on them at the most precious
moments....;)) 

CC to IR-list, there's a tendency there too to regard digi-IR as the
best thing since sliced bread (while they would cry even harder,
since the preparation for IR is a lot more tedious)....;))
