B + W 55mm UV MRC Coated B+W Code - BW70216 The B+W UV Filters block the invisible UV component of light from the sky, which can cause blur and to which many color films react with a blue cast. These filters should be called UV-Blocking Filters, because there are filters for technical applications that pass UV radiation and block all the other wavelengths. Nevertheless, the short term “UV Filter” has become established among photographers. UV filters are ideal for photography in high altitudes (in the mountains), by the sea and in regions with very clean air. The pictures gain brilliance and disturbing blue casts are avoided. Because the glass is colorless, color rendition is not altered, aside from the elimination of the unwanted blue cast, and no increase in exposure is required. The B+W UV filters are suitable as a filter for lens protection, guarding the lens against dust and damage, and it can be used and kept on the lens at all times. UV filters are recommended for color and black-and-white film photography as well as digital photography. MRC (Multi-Resistant Coating) by B+W is not only an effective multiple layer coating, it is also harder than glass, so that it protects filters from scratches (for instance when cleaning the filters), and it is also water and dirt repellent, thus facilitating filter cleaning and maintenance. The 55 mm B&W filter features MRC - Multicoated Glass, and brass F-PRO standard mounts.  |
