Breakthrough X4 Circular Polarizer 39mm

The Breakthrough Photography 39mm X4 UV 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. To prevent internal ghosting and reflections while providing 99.4% light transmission, each glass surface includes eight layers of anti-reflection coating. 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. The Nano coating associated with X4 UV filters provides an additional ninth layer over the front MRC, resulting in an improved beading effect when in contact with water for greater cleaning efficiency.

This Breakthrough Photography UV filter is constructed from Schott glass for increased optical clarity as well as color fidelity and features a thin brass filter ring to minimize the potential for vignetting while enhancing durability and jamming prevention. It is also weather-sealed and 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.
