Relative Humindity

As a last entry here I'd like to note just for the
record that my Canon 300D is claimed in the manual
to operate between 0 and 40C or 32 - 104F at 85% or
less humidity. I take the 40C as a too round number
so that testing likely shows almost perfect performance
a few degrees higher. Same with the 85%.

I know for a fact that the camera will operate down to
20F or about -7C.

I assume that other dSLRs are similar.
