Rapid changes in temperature can
cause problems with condensation. When taking a warm camera to a
cold environment any warm moist air accumulated inside the camera
body and lens can cause condensation. The opposite happens when a
cold camera is brought inside to a warm moist environment resulting
in condensation on the exterior surfaces.
A well known photography tip is to
place the camera inside a plastic bag before taking it from one
temperature extreme to another. This allows the camera acclimate to
the new temperature inside the plastic bag.

photography tip to avoid lens fogging and potential condensation
