NiSi Cine Filter Nano IRND 4x4"""" 0.9

NiSi Cine Filter Nano IRND 4x4" 0.9 – Neutral density for wider apertures and slower shutter speeds

This NiSi Cine Nano IRND reduces exposure across the entire image so you can shoot with a wider aperture or a slower shutter speed than would normally be required. As a result, you gain practical control over depth of field and the ability to convey movement more easily in your footage or photos.

How it helps your filming and photography

Use the filter when you need to slow exposure time or open the aperture without overexposing the image. For example, you can obtain a shallower depth of field at bright light levels or create motion blur for a more cinematic look. The filter darkens the scene uniformly, so you maintain consistent exposure control across the frame.

Designed for accurate color and digital sensors

NiSi designed this neutral density filter to minimise color shifts. It is optimised for use with digital sensors and promotes nearly flat attenuation of both visible and infrared light. In practice, that helps eliminate unwanted color casts and preserves cleaner, truer blacks when you increase exposure times.

Key features

• This NiSi Nano IRND Filter is constructed from optical glass for clarity and color fidelity.
• The neutral density characteristic darkens the image, allowing photography with a longer shutter speed or wider aperture than normally required.
• By reducing exposure you can control depth of field and convey movement more easily in your images.
• The filter is intended not to affect the coloration of the image and is ideal for use with other filters.
• Each surface includes one layer of NiSi Optical Nano Coating that attenuates infrared light as well as visible wavelengths, to maintain color neutrality and suppress color casts due to increased exposure times.
• Scratch resistance.
• This filter is 4mm thick.
• Constructed from optical glass for clarity.
• Leatherette pouch included for storage and transport.

Typical use cases

• Shooting with a wide aperture in bright conditions while keeping correct exposure.
• Creating motion blur with slower shutter speeds for cinematic effects.
• Stacking with other filters when balanced color neutrality is required.
• Working with digital sensors where infrared attenuation helps prevent color shifts.

FAQ

Question: Will this filter change my image colors?
Answer: The NiSi Nano IRND is intended not to affect coloration. It includes NiSi Optical Nano Coating on each surface to attenuate infrared and visible wavelengths, which helps maintain color neutrality and reduce color casts during longer exposures.

Question: Can I use it together with other filters?
Answer: Yes. The filter is described as ideal for pairing with other filters, allowing you to stack filters when needed while preserving coloration.

Question: Is this filter suitable for digital cameras?
Answer: The filter is optimised for use with digital sensors and promotes nearly flat attenuation of visible and infrared light to reduce the risk of sensor-related color shifts.

Question: What does the coating do and how many layers are applied?
Answer: Each surface receives one layer of NiSi Optical Nano Coating. The coating attenuates infrared as well as visible light to help keep colors neutral and produce cleaner blacks during increased exposure times.

Question: What is included in the package and is the filter durable?
Answer: The filter is constructed from optical glass for clarity and color fidelity, features scratch resistance, and comes with a leatherette pouch for storage and transport.
