Rectangular 75 by 80 millimetre neutral density filter with nano coating on both sides

iKan

iKan 75x80mm Nano IR ND8 0.9 (3-Stop) Neutral Density Filter

SKU CH-0W9C-W4DFR

Reduces light by three stops for long exposures and motion blur while maintaining true colour and preventing infrared contamination

  • True-to-life color with no cast from high-quality optical glass
  • 3-stop light reduction enables slower shutter speeds and wider apertures
  • Nano coating on both sides repels water and oil while preventing detail loss
  • Infrared protection layer eliminates IR light for cleaner long exposures
  • Compatible with NiSi M75 filter system for versatile setup

Bright-Light Exposure Control

The iKan 75x80mm Nano IR ND8 0.9 filter reduces light by three stops for photographers and videographers who need slower shutter speeds or wider apertures under strong illumination. It fits the NiSi M75 holder system and uses optical glass rather than resin to maintain image fidelity.

Optical Performance Traits

Multi-layer nano coating on both surfaces repels water and oil while preserving high-definition detail across the frame. The infrared protection layer blocks IR contamination that can shift colours during long exposures, and the design avoids vignetting on compatible wide-angle lenses.

Workflow Advantages

The hydrophobic and oleophobic coating lets rain or fingerprints wipe clean without solvents, keeping sessions running in changeable weather. True-to-life colour rendering removes the need for corrective grading caused by colour casts common in lesser filters.

Questions about this item

How do I mount the 75x80mm filter in the NiSi M75 holder without vignetting?

Slide the glass into the M75 holder’s front slot until it seats flush; the 75x80mm size matches the holder aperture exactly, so vignetting only appears if a second filter is stacked behind it or the lens hood intrudes.

What long-term care does the nano coating on both sides require?

Rinse dust off with lukewarm water, then wipe gently with a microfibre cloth; the water- and oil-repellent coating resists smudges but can be scratched by abrasive fabrics or grit pressed into the surface.

At what exposure length does infrared leak become visible with the IR-blocking layer?

The IR coating is designed for exposures up to 5 minutes in bright sun; beyond that, near-infrared signal can accumulate and appear as a magenta cast in shadows.
