The NiSi 40mm PRO UV Filter for Camera Lens Protectionis 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, which maximizes light transmission to help eliminate the appearance of internal ghosting or reflections. Additionally, one layer of NiSi Optical Nano Coating is applied to each of this filter's surfaces to create an improved beading effect when in contact with water for greater cleaning efficiency.

NiSi PRO UV filters are constructed from optical glass for clarity as well as color fidelity. This filter features a brass filter ring to enhance durability and jamming prevention.

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.
