NiSi 150x150mm Nano IR Neutral Density filter - ND4 (0.6) - 2 Stop

The NiSi 150x150mm Nano IR ND4 (2-Stop) filter is a fixed neutral density filter built for the NiSi 150mm filter system, aimed at photographers who need moderate light reduction for waterfalls and flowing water at shutter speeds between 0.25 and 2 seconds. Its Nano coating and infrared protection layer keep color true to life rather than shifting toward red at small apertures. It's sized for cameras and lenses that lack a standard filter thread.

• 2-stop (0.6 density) exposure reduction: Commonly used for waterfalls and water flow at 0.25-2 second shutter speeds.
• Infrared protection coating: Prevents the red color cast that unprotected ND filters can introduce at small apertures.
• High-quality optical glass with Nano coating: Preserves true-to-life color rather than resin-based alternatives.
• Fits the NiSi 150mm filter system: Sized for cameras and lenses without a standard filter thread.
