To answer this, the imaging window will not fog up, and i know this because i used a fridge like this in the winter time.
The cmos will stay about 10C while the inside of the box can be about -12.

At the moment i am modding my 40D to directly cool the cmos with an peltier and i can get the cmos as cold as -14C when working, or about 25C below ambient, have to make it better regulated to keep it at 5C.

Hope i didn't dwell too far of this thread
