Is there a problem with taking cameras out to the extreme cold Like 0 degrees Fahrenheit?

In short, yes.
Most older film cameras were lubricated with water based lithium grease. It can freeze. It used to be the norm to have them cleaned and lubricated with cold weather type grease for extended periods out side.

Both of my digital SLR cameras (Nikon & Canon) say not to use them below 32f or above 104f.

Condensation can also become an issue with some cameras.

I would check with your camera manufacturer for more specific instructions on your particular camera.

Thanks for asking that question - I was not aware of the problems that may be incurred - I could think logically , but did not know- I assume If i can operate in that temperature , all else should be able

I can't operate at 0 degrees F, so if my cameras are outside, they are out there alone

I just checked 4 Canon manuals, the 3 dslr's say don't charge the batteries unless room temp. No mention is made about camera in cold temp other than the condensation problem when coming in from the cold. The Powershot SX110 IS says 0-104.

I have used all of these cameras in below 0 temps with no adverse consequences, other than really short battery life and slow autofocus on the SLR's.
I think the worst that would happen is it won't operate. Just keep spare batteries inside your coat.

You're right somewhereinusa. It does not specifically say "do not use them".
In my Nikon D90 manual on page 272 under camera operating conditions it shows an operating range of
Temperature - 0-40 degrees centigrade(32-104 F).
In my Canon 400D operators manual on page 170 under the heading of Operation Environment - Working Temperature range it says 0-40C (32-104F). Neither manual mentions battery charging in this section.
While it doesn't say not to, would that not be the assumption that you shouldn't for some reason? And that is why I suggested to contact his specific camera manufacturer for advice.

In addition to that, Olympus recently put out 2 P&S digital cameras they market as "freeze proof". I wonder why.
