NiSi Cine Filter Nano FS ND 4x5.65"""" 1.8 (6stop)

NiSi Cine Filter Nano FS ND 4x5.65" — 1.8 (6-stop) Neutral Density for accurate and consistent exposure

This NiSi Cine Nano FS ND filter delivers true-to-life images while giving you precise and consistent exposure control. The 4"x5.65" format is available across multiple density options, including the 1.8 (6-stop) version referenced here.

Key features

• Pure neutral color. The filter maintains a neutral color balance, providing consistent color rendering across the available densities from 0.3 to 2.4.
• True-to-life images. This filter is designed to capture images that reflect natural color and tone without introducing unwanted color casts.
• High-quality optical glass. The glass features precise flat and parallel surfaces that help guarantee image sharpness throughout the frame.
• Accurate, consistent exposure control. Use the ND densities to control exposure reliably across different lighting conditions and scenes.
• Eliminates IR pollution. The filter removes infrared pollution that can affect image quality on any camera, helping preserve accurate color and detail.
• Titanium coating for durability. A titanium coating protects the filter surface to support long filter life.
• Hydrophobic and oleophobic finishes. These coatings make the filter easy and fast to clean by repelling water and oils.
• Anti-reflective coating. Cutting-edge anti-reflective treatment minimizes flare and helps preserve overall image contrast.
• Stable optical properties. The filter’s optical characteristics are permanently stable and will not fade over time.

Benefits and practical use

Apply this ND filter when you need reliable light reduction without changing color reproduction. Its neutral color balance and IR suppression help maintain accurate skin tones and natural colors in both video and still photography. The robust coatings reduce maintenance and protect the optical surface, while the flat, parallel glass preserves sharpness across the image.

Available models and densities

The NiSi Nano FS ND series is offered in the 4"x5.65" format and in multiple density steps. The densities cover a continuous range from light to strong attenuation, allowing you to select the exact exposure reduction you need, including the 1.8 density (marked as 6-stop).

FAQ

Question: Does this filter change color balance?
Answer: The NiSi Nano FS ND is designed for pure neutral color and consistent color rendering across densities from 0.3 to 2.4, so it does not introduce noticeable color shifts.

Question: How do I clean the filter?
Answer: The filter has hydrophobic and oleophobic coatings which make cleaning easy and fast—these finishes repel water and oils to simplify maintenance.

Question: Will this filter help with infrared (IR) issues?
Answer: Yes. The filter eliminates IR pollution on any camera, reducing IR-related color contamination and helping preserve accurate colors and detail.

Question: Which sizes and densities are available?
Answer: This Nano FS ND series is available in the 4"x5.65" size and in densities of 0.3, 0.6, 0.9, 1.2, 1.5, 1.8 (6-stop), 2.1 and 2.4, allowing you to choose the level of exposure reduction you need.

Question: How does the filter affect image sharpness and contrast?
Answer: The filter uses optical glass with precise flat and parallel surfaces to help guarantee sharpness, and its anti-reflective coating minimizes flare while preserving overall contrast.
