The green MeFOTO 49mm Lens Karma 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 over 98% light transmission, each glass surface includes multiple layers of anti-reflection coating.
MeFOTO filters are constructed from Asahi glass that provide optical clarity and color fidelity. This filter features a green-colored aluminum-alloy filter ring that helps provide a more distinctive appearance to your equipment.
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.
