The B+W UV Haze MRC 010 F-Pro Filter is designed to absorb ultraviolet light and reduce the bluish cast of daylight. Aside from the reduction of unwanted blue casts, no additional coloration or contrast is created, and adjustments to exposure are not required while using this filter. B+W filters are constructed from Schott glass for increased optical clarity and colour fidelity. This filter features an F-Pro brass filter ring for durability as well as jamming prevention. This UV filter is also useful as a general protective filter to leave on lenses at all times. Such filters help to reduce dust and moisture from reaching your front lens element and provide additional protection in case of drops or situations where scratching could occur.
