NiSi Square Nano IRND 150x150mm ND4 2 Stops

The NiSi Nano IR Neutral Density (ND) filter is specifically designed for landscape photographers seeking high-quality optical performance. Constructed from premium optical glass (not resin), this filter features a nano coating on both sides to preserve every detail without loss.

Neutral density filters reduce light intensity without affecting image coloration. However, cameras become sensitive to infrared (IR) light when using ND filters, which can cause unwanted red color casts in photos taken at small apertures. To address this, the NiSi Nano IRND filter incorporates an infrared protection coating layer that effectively blocks IR light passing through the lens, restoring natural color fidelity.

Key Features:

• Ultra low color cast and ultra low reflection for true-to-life images
• No vignetting, ensuring even exposure across the frame
• High definition optical clarity
• Nano coating on both sides provides water and oil repellency for easy cleaning and durability
• Made from environmentally friendly optical lens glass (H-K9L)

Specifications:

• Filter size: 150 x 150 mm
• Density: ND4 (2 stops light reduction)
• Material: High definition optical glass with nano coating
• Infrared protection coating to eliminate IR light interference

This filter enables longer exposure times, expanding creative possibilities while maintaining realistic and vibrant colors thanks to its IR technology. Available in multiple density steps including 2, 3, 4, 5, 6, 10, and 15 stops.
