Photographers may be disturbed by condensation on camera lens in night time and cold weather, happening on 10℉(5℃) temperature difference of dew-point and ambient temperature. STC E-warmer Defog Filter is the one and only solution that applies ITO(Indium Tin Oxide) coating on 1mm optical glass that you can warm up the glass evenly and reduce the fog on your lens.
