NiSi Cine Filter Nano IRND 4x5.65"""" 1.5

NiSi Cine Filter Nano IRND 4x5.65"""" 1.5 – Exposure reduction for wider apertures and slower shutter speeds

This NiSi Nano IRND filter reduces exposure across the entire image so you can shoot with a wider aperture or a slower shutter speed than you normally would. By lowering the amount of light reaching the sensor, you gain creative control over depth of field and motion depiction in your footage or photos.

Key features and benefits

• Provides exposure reduction and darkens the entire image, allowing longer shutter times or larger apertures than usual.
• Helps you control depth of field more easily and lets you convey movement through slower shutter speeds.
• Designed not to affect the coloration of the image, making it ideal to use alongside other filters without introducing unwanted color shifts.
• Optimized for use with digital sensors and engineered to promote nearly flat attenuation of both visible and infrared light.
• Each surface of the filter receives one layer of NiSi Optical Nano Coating to attenuate infrared light as well as visible wavelengths, helping maintain color neutrality and suppress color casts during longer exposures.
• Constructed from optical glass for clarity and color fidelity.
• Provides scratch resistance to help protect the optical surface during use.
• The filter measures 4mm in thickness.
• A leatherette pouch is included for storage and transport.

Design and optical performance

NiSi engineered this Nano IRND filter with digital sensors in mind. The design aims for nearly flat attenuation across visible and infrared spectra, so the filter maintains neutral color balance even when you increase exposure times. To support this, the manufacturer applies one layer of NiSi Optical Nano Coating to each surface. This coating attenuates infrared as well as visible wavelengths, which helps keep blacks cleaner and reduces color casts during extended exposures.

Materials and durability

The filter uses optical glass to ensure clarity and preserve color fidelity in your images. In addition, the surface receives treatment for scratch resistance. These choices combine to provide a durable filter that performs optically while standing up to normal field use.

FAQ

Question: Will this filter change the color balance of my footage or photos?
Answer: The NiSi Nano IRND is intended not to affect image coloration. Its design and the Nano Optical Coating on each surface attenuate both visible and infrared light to help maintain color neutrality and reduce color casts during longer exposures.

Question: Can I stack this filter with other filters?
Answer: Yes. Because the filter is made to avoid affecting overall coloration, it is suitable for pairing with other filters without introducing significant color shifts.

Question: How does this filter affect creative control when shooting?
Answer: By reducing exposure uniformly across the image, the filter lets you use wider apertures for shallower depth of field or slower shutter speeds to capture motion blur. This gives you more flexibility to shape depth and movement in your shots.

Question: Is the filter durable for regular field use?
Answer: The filter is constructed from optical glass and includes scratch resistance, and it ships with a leatherette pouch for storage and transport to help protect the surface when not in use.
