NiSi 52mm Natural Night Filter (Light Pollution Filter)

The NiSi 52mm Natural Night Filter is NiSi's first filter built specifically for night photography, designed to block the mercury vapor, sodium, and low-CRI streetlight wavelengths that cause sky glow and wash out night images. Precision annealed optical glass keeps it sharp enough for today's high-megapixel cameras, while a multi-layer NANO coating cuts reflections that cause ghosting and flare. The same coating also makes it easy to wipe off water, dust, and oil without scratching the glass.

• Blocks light pollution wavelengths: Filters out common light pollution sources like mercury vapor, sodium, and low-CRI streetlights that wash out night skies.
• Precision optical glass: Finely ground and polished, precision annealed glass maintains sharpness for high-megapixel cameras.
• Multi-layer NANO coating: Reduces reflections that cause ghosting and flare without any loss of sharpness.
• Easy-clean protective layer: The coating's protective layer makes it easy to wipe off water, dust, and oil without scratching the glass.
