NiSi Square Nano IR GND Soft 150x170mm GND8 0.9

NiSi Square Nano IR Soft Graduated Neutral Density Filter 150x170mm

The NiSi Nano Soft Graduated IR ND filter is specially designed for landscape photographers. It is made from high-quality optical glass (H-K9L) with nano coating on both sides to preserve detail and prevent water and oil contamination.

The filter features a soft graduated neutral density design, with the darkest area at the top gradually transitioning to clear at the bottom, allowing balanced exposure between bright skies and darker foregrounds. This soft edge transition is ideal for scenes where the boundary between light and dark areas is not sharply defined, such as mountainous landscapes.

Neutral density filters do not affect the coloration of the image, and this filter includes an infrared protection coating layer to eliminate unwanted infrared light that can cause red color casts when shooting at small apertures. The filter can be repositioned in the holder to recompose the photo for optimal results.

Key Features:

• Constructed from high-quality optical glass (H-K9L) for clarity and color fidelity
• Soft graduated neutral density design with a smooth transition from dark to clear
• Infrared protection coating to eliminate infrared light and maintain natural colors
• Ultra-low color cast and ultra-low reflection
• No vignetting
• High resolution
• Nano coating on both sides, water and oil repellent

Specifications:

• Size: 150 x 170 mm
• Density: GND8 (0.9 ND, approx. 3 stops)

This filter is recommended for use with wide-angle and normal focal lengths and is optimized for digital sensors to provide nearly flat attenuation of visible and infrared light, ensuring cleaner, truer blacks and eliminating color casts.
