NiSi Cinema 4×5.65 Inch Nano IRND Hard-Edge Graduated 0.9 Filter (3 Stop)

The NiSi Cinema 4×5.65 Inch Nano IRND Hard-Edge Graduated 0.9 Filter selectively darkens bright areas of your image, such as skies, while leaving the remainder of the frame unaffected. Constructed from optical glass with NiSi’s exclusive dual-sided Nano coating technology, this filter delivers superior optical clarity and infrared light control perfect for professional cinema work. The hard-edge graduated transition makes it ideal for scenes with flat horizons, such as landscapes and desert environments where the transition between light and dark areas is sharp and defined.

• 3-stop neutral density reduction (0.9 optical density) enables slower shutter speeds and wider apertures in bright conditions
• Dual-sided Nano coating provides infrared light control, scratch resistance, and water/oil repellency for durability and easy maintenance
• Hard-edge graduated design creates a fast, sharp transition line for flat horizon applications
• 4mm thickness compatible with standard 4×5.65 inch matte boxes and filter cage systems
• Ultra-low colour shifting with anti-reflective coating delivers neutral results suitable for 6K digital cinematography
