The E49 UVa II 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, this filter includes multiple layers of anti-reflection coatings.
This filter is constructed from optical glass for clarity as well as color fidelity. It also features a black, aluminum-alloy filter ring for durability while remaining lightweight.
The E49 UVa II Filter is designed to mount onto a lens with 49mm front filter threads. It is useful as a general protective filter to leave on a lens 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.
