Terry,
I recommend strongly against this. When water freezes, it expands and
the expanding pressure inside a camera could crack glass lenses and even
metal structural elements. Note how the expansion of water when it
freezes even causes rock to fracture. It would seem counterproductive to
do this inside a precision instrument such as a camera.
When "winterizing" normal cameras for use in extreme cold temperatures,
technicians even remove the normal grease on gears and motors, and
replace it with a "dry" lubricant such as graphite. This prevents
freezing and any resulting damage inside the camera or lens.
