NiSi Cinema 4x4" Nano IRND Soft-Edge Graduated 1.2 Filter (4 Stop)

Overview

The NiSi Cinema 4x4" Nano IRND Soft-Edge Graduated 1.2 Filter (4 Stop) is a professional graduated neutral density filter designed to selectively darken bright areas of a scene, such as skies, while leaving the rest of the frame unaffected. It is ideal for balancing exposure in high-contrast scenes where the brightness difference between sky and foreground exceeds the camera’s dynamic range.

Built from a single piece of high-quality optical glass, this 10.2 x 10.2 cm filter features a soft-edge graduated transition that blends gradually from dark to clear. This makes it especially well suited to uneven horizons such as mountains, trees, or city skylines. NiSi’s Nano IR coating technology helps minimise infrared contamination, preserve neutral colour balance, and maintain rich blacks, while the dual-sided nano coating protects the surface from water, oil, and scratches.

Core Features

• This graduated neutral density filter reduces exposure by 4 stops in the darkened area while leaving the remainder of the image clear.
• Its soft-edge transition is designed for scenes with uneven horizons, including mountains, cityscapes, and natural landscapes.
• Nano IR coating helps minimise infrared pollution and unwanted colour shifts for cleaner, more accurate results.
• Dual-sided nano coating reduces reflections while also resisting water, oil, and scratches for easier maintenance.
• The optical glass construction supports high-resolution image capture with excellent sharpness and neutral colour reproduction.

Designed for High-Contrast Scenes

Graduated ND filters help compensate for the difference between what the eye can see and what a camera sensor can record in a single exposure. This filter is particularly useful when you need to hold detail in bright skies while maintaining a normal exposure in darker foreground elements.

Built for Cinema Workflows

The 4x4" format is suitable for professional matte box use and also pairs well with the NiSi C4 Cinema Holder for a lightweight and fast-mounting setup on lenses with standard filter threads. A leatherette pouch is included for convenient storage and transport.
