Fogging

[bvsolutions]

Has anyone out there figured out how to keep the polar-pro lenses from condensation fogging in very cold conditions? -25 to -30.

It is hard to get sharp photos, and the ND lens freezes to the camera lens.

Set the craft out in the cold for a few minutes before flying - to equalize the temperature. Keep the batteries nice and warm during this time.

Put both the aircraft and filter outside separately, and only install the filter when both have cooled. If you install the filter inside you'll get warm humid air trapped between filter and camera that will condense when it cools...
