Description
The NiSi 40.5mm 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.
