Overview

The NiSi ND1000 100x100mm Nano IR Neutral Density Filter is designed for photographers who need precise control over exposure in bright conditions. By reducing light transmission by 10 full stops, it opens up creative possibilities that are otherwise impossible in daylight — silky water, streaking clouds, and motion blur effects that require shutter speeds measured in seconds or minutes. What distinguishes this filter from many competitors at similar density levels is its IR (infrared) protection layer, which blocks the infrared contamination that causes the reddish-magenta color cast plaguing many high-density ND filters. The result is true-to-life color reproduction even at extended exposure times.

Constructed from high-definition optical glass rather than resin, the NiSi ND1000 maintains edge-to-edge sharpness and avoids the image softening that lower-quality ND filters can introduce. Both surfaces feature NiSi's proprietary Nano coating, which serves multiple purposes: it minimizes reflections and flare, repels water droplets during outdoor use, resists scratches from routine handling, and makes cleaning straightforward with a simple wipe. The 100x100mm square format with 2mm thickness ensures compatibility with standard 100mm filter holder systems, giving photographers the flexibility to use a single filter across their entire lens collection rather than buying separate circular filters for each lens diameter.

Key Features

True to life color, No color cast

3.0 density provides a 10 stop reduction of light entering the lens, while still providing true to life color

No Vignetting

Compatible with systems that hold 100x100mm (2mm thick) filters

High definition optical glass with NiSi Nano Coating on both sides - waterproof, anti-reflection, scratch resistant, and easy to clean

Pros & Cons

👍 Pros

  • IR coating effectively eliminates the warm color cast common in cheaper 10-stop ND filters.
  • High-definition optical glass maintains sharpness across the frame without softening.
  • Dual-sided Nano coating repels water and fingerprints, making field cleaning quick.
  • Square 100mm format works across multiple lenses without needing separate circular filter sizes.
  • 2mm thickness fits standard 100mm holder systems without requiring adapters.

👎 Cons

  • Square filter format requires a separate holder system, adding cost if you do not already own one.
  • At 10 stops, exposure calculations can be tricky without a dedicated ND calculator app.
  • The glass is rigid and can chip if dropped on hard surfaces despite the scratch-resistant coating.
  • Only available in the 100x100mm size, so it cannot be used on smaller filter systems.

Frequently Asked Questions

No. The Nano IR coating blocks infrared light contamination, which is the primary cause of color shifts in high-density ND filters. Colors remain true to life.
It fits any system that accepts 100x100mm square filters with a 2mm thickness, including NiSi's own V5, V6, and V7 holder systems as well as comparable third-party holders.
It provides a 10-stop (ND1000, 3.0 density) reduction, allowing dramatically slower shutter speeds for long-exposure effects in daylight.
The dual-sided Nano coating makes the glass surface scratch-resistant, waterproof, and easy to clean, reducing the likelihood of water spots and fingerprint smudges.
NiSi states it produces no vignetting. The 100x100mm square format and 2mm thickness are designed to minimize corner darkening even at wider focal lengths.
