B + W 43mm UV Filter MRC Coated B+W Code - BW40228 The high quality B+W UV filters are a popular choice with Colour and black and white applications, and digital SLR photography. 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. UV Filters are popular as a lens protection filter, guarding the lens against dust and damage, and it can be used and kept on the lens at all times. 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. B&W filters feature MRC - Multicoated Glass, and brass F-PRO standard mounts |
