E-Warmer Defog Filter
Features
Product Detail
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.
A semiconductor-based sensor was built-in the control that connects to the filter on the one side and connect to the power bank on the other side. You can choose flash light mode or heat-up mode in different temperature of your free choice.
And the filter itself is like those STC filter peer of multiple coating and is of high level transmittance and strong enough to protect of your lens.
