The 49mm UV Filter from 7artisans Photoelectric 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 are created, and adjustments to exposure are not required while using this filter. To prevent internal ghosting and reflections, each glass surface includes multiple layers of anti-reflection coating. These coatings also offer greater protection to the filter substrate and help it to stay clean for longer than with uncoated filters.
This UV filter is constructed from optical glass for increased clarity as well as color fidelity and features a aluminum-alloy filter ring for durability while remaining lightweight. It 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.
