prmolina: The "tough" cameras I've seen are for Freezebabies:
14 F is just not tough enough for routine cold in the Upper Midwest of the US. Adventure cameras have been stuck there for too long while manufacturers are infatuated with other specs. Those of us who routinely leave the house up here need something tougher, let alone for weinter adventuring. Give us something to use when we go ice skating, snowmobiling, xc skiing, snowshoeing, winter camping, winter carnivals, innertubing, ice sculpting, winter walks, shoveling, polar plunges, ice fishing and fercristsake just day in day out activities. For those of us who know and love winter, 14 F just doesn't really cut it.

Yes, you are right - I forgot the whole range of automotive grade comps qualified to AEC-Q101 (requires -40 min op. temp). Military comps are still normally specced at -55 C min though.
The Automotive grade comps are special qualification lines at various vendors, applied to specific lines that are in demand by the auto industry, and are more expensive than the industrial-range components. They are used for important functions in cars - e.g. engine control / safety. I doubt that you radio contains such comps - it may or may not work at -40.
Now, for your original question - yes, it is possible to produce DSLR or P&S electronic camera to work at below 13F, but in addition to appropriate discrete components it demands a whole different system engineering and qualification e.g. the operation of the focusing/zoom mechanism (advanced lubrication etc), stresses due to different thermal expansion coeff., distortion of optical path atc. Probably not cost effective for the general public.

For that, you need to go the the "old school" film camera Nikon FM2. Good to -40 F/C and can take a beating.
I doubt that any advanced electronic camera can stand -10 F or below w/o heating - industrial grade components aren't normally specced below that - LCD especially. And no vendor would use military grade comps for the consumer space.
