The UV-IR Cut #486 MRC Basic Filter from B+W is a 72mm ultraviolet and infrared control filter that is useful for digital cinematography and still photography. When used, 88% of ultraviolet light waves are blocked at 380 nanometres, along with 95% of infrared light waves at 700 nanometres, ensuring that light limited to the visible spectrum is recorded. When used along with multi-stop neutral-density filters, potential infrared colour shifts are prevented or minimized, preserving colour accuracy throughout the frame. This filter also reduces unwanted blue castes while recording digital video or still photos under daylight that also features intense ultraviolet light. B+W MRC Basic filters are made with the exclusive Multi-Resistant Coating (MRC) nano premium coating technology. This high-quality broadband coating is applied on both sides and enhances the optical imaging properties, allowing uniform and increased transmittance across the entire light spectrum to be achieved, with minimal physically induced remaining reflection. The nano all-around protection on the filter glass also ensures increased scratch resistance and extremely fast, easy cleaning, providing a long filter life. The slim filter ring design is compatible with wide-angle lenses with an equivalent width of a 17mm full-frame lens. The top knurling is redesigned for enhanced gripping. 88% of ultraviolet light waves are blocked at 380 nanometres, before which they are further removed, reducing bluish cast of daylight when recording video or still photos. 95% of infrared light waves are blocked at 700 nanometres, after which they are progressively eliminated. Useful with CCD or CMOS sensors to filter out infrared light pollution that causes colour shifts frequently associated with high-definition recording with multi-stop neutral-density filters. Does not require adjustments to exposure while in use. Thirty layers of interference coatings on the front surface limit light that falls on a digital camera sensor to the visible spectrum. Multicoated rear surface prevents internal ghosting and reflections. Constructed from Schott glass for optical clarity. F-Pro brass filter ring helps to prevent jamming and provides additional strength. 55mm front filter threads allow use with other filters to protect the front surface or combine with other effects. Plastic case for storage and transport.
