B&W 30mm Ultraviolet (UV) Glass Filter are wise initial investments. They help protect your valuable investment from dust, moisture and scratches, which can lead to costly repairs.
This UV filter blocks the invisible UV component of light from the sky which can cause blur and to which many color films react with a blue cast. Because the glass is colorless, color rendition is not altered, aside from the elimination of the unwanted blue cast. No increase in exposure is required.
