When water hits the filter, it spreads into a film over the glass instead of forming droplets. This helps to maintain a clear view under a variety of weather conditions and for taking photos or video around water.
Through a special treatment of the hydrophilic surface, this filter is also extraordinarily durable.
This self-cleaning filter helps to keep dust and debris away with exposure to the sun or UV light, prolonging the life and performance of the filter.
