The B+W 105mm UV Haze MRC 010M Filter is a general use, clear filter 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. This Multi-Resistant Coating (MRC) also offers greater protection to the filter substrate and helps it to stay clean for longer than with uncoated filters. This UV filter is also useful as a general protective filter to leave on lenses at all times. Creates no additional coloration or contrast.
