NiSi Cine Filter Nano IRND 4x4 2.1

NiSi Nano IRND Filter

The NiSi Nano IRND Filter is a neutral density (ND) filter that reduces exposure and darkens the entire image, allowing photography with a wider aperture or slower shutter speed than normally required. By slowing exposure time or increasing aperture, it enables better control of depth of field and easier conveyance of movement. ND filters are designed not to affect image coloration and are ideal for use with other filters.

Optimized Design for Digital Sensors

This filter is optimized for digital sensors to provide nearly flat attenuation of visible and infrared light. To ensure high neutrality across visible and infrared spectrums, eliminating color casts and ensuring cleaner, truer blacks, each surface of the filter is coated with one layer of NiSi Optical Nano Coating.

Key Features

• Constructed from optical glass for clarity and accurate color fidelity.
• Neutral density effect darkens the image, allowing longer shutter speeds or wider apertures.
• Enables control over depth of field and better expression of motion.
• Does not affect image coloration; ideal for use with other filters.
• Each surface has NiSi Optical Nano Coating that attenuates infrared and visible wavelengths to maintain color neutrality and suppress color casts from longer exposures.
• Scratch resistant surface.
• Filter thickness: 4 mm.
• Includes a leatherette pouch for storage and transport.
