Revolutionary Precision: NiSi Full Spectrum FS Nano Cinema Neutral Density Filter – 4×5.65”
Discover the new NiSi Full Spectrum Cinema FS ND filters, designed to control the amount of light reaching the sensor. This exceptional filter allows shooting at wider apertures or slower shutter speeds, making it perfect for capturing high-quality video with ease. Ideal for filmmakers and cinematographers seeking unmatched control over lighting conditions.
The Full Spectrum ND filter ensures pure, neutral color rendition across the entire FS ND range. Say goodbye to color casts and achieve authentic, vibrant images. A must-have for professionals who demand accurate color reproduction in their work.
Crafted from exclusive NiSi precision optical glass, it delivers maximum transmittance, sharpness, and faithful color reproduction.
This chart illustrates the light transmission across a series of photographic filters, which directly impacts your exposure.
The term “External Spectral Transmittance on Optical Axis” refers to how light passes through the filters across wavelengths measured in nanometers (nm), from 400 nm (near ultraviolet) to 900 nm (near infrared).
The horizontal axis shows wavelength in nanometers, while the vertical axis represents optical attenuation in T-stops, a measure of light reduction. Each line corresponds to a different filter, labeled (e.g., “FSND0.3” or “FSND2.4”), where higher numbers indicate denser filters that allow less light through.
The lines are very flat, meaning these filters provide uniform light attenuation across all wavelengths. This ensures that colors in your footage are not altered by the filter. The lower a line appears on the graph, the less light it transmits, requiring corresponding exposure adjustments on your camera.
Full Spectrum FS ND Filter
The NiSi Full Spectrum Cinema FS ND Filter represents the pinnacle of filter technology. Its solid neutral density effectively reduces the amount of light entering your lens, providing enhanced control.
This is essential for photographers and filmmakers who demand precise light management, ensuring every shot is perfectly balanced.
The new NiSi Full Spectrum ND (FS ND) range transmits light evenly across ultraviolet, visible, and near-infrared wavelengths. It produces perfectly neutral colors while preserving fine detail without compromising optical performance.
The NiSi FS ND filter is made from environmentally sustainable H-K9L optical crown glass. Its production involves precision annealing, carefully controlled heating and cooling cycles, and extended cooling times to eliminate internal stress and prevent deformation. Compared to standard glass, H-K9L offers superior neutral light transmission, excellent physical and chemical uniformity, and precise optical consistency.
A new titanium “Ti” coating applied on both sides, along with an advanced anti-reflective coating, minimizes flare and reflections. It significantly reduces or eliminates unwanted reflections between the lens and the filter.
The filter edge is coated with a specialized matte material imported from Japan, designed to suppress ghosting and various forms of flare.
Versatile Aperture and Shutter Control
This innovative filter gives you the freedom to shoot with wider apertures or slower shutter speeds. This flexibility is essential for achieving shallow depth of field or motion blur effects, adding a dramatic and artistic touch to your footage. Whether shooting in bright natural light or controlled studio environments, this filter is an indispensable creative tool.
Pure Neutral Color Reproduction
The NiSi Cinema FS ND filter guarantees consistent neutral colours across all densities, ensuring your images capture the true essence of the scene. This consistency is crucial for professionals who require accurate color rendering to convey story and emotion effectively.
Premium Optical Glass Quality
Made from exclusive NiSi precision optical glass, this filter delivers exceptional sharpness in every shot. It is designed for those who demand uncompromising clarity, ensuring crisp and detailed images even in challenging conditions.
Infrared (IR) Blocking Treatment
This filter effectively eliminates infrared light on any camera, preventing unwanted IR contamination in photos and videos. This is especially important for maintaining accurate color and avoiding common color shift issues.
Easy-Clean Coatings
Hydrophobic and oleophobic coatings make the filter quick and easy to clean. Say goodbye to stubborn smudges and fingerprints, and keep your filter in perfect condition with minimal effort—ideal for professionals working in fast-paced environments.
Advanced Anti-Reflection Performance
The advanced anti-reflective coating minimizes reflections while preserving overall contrast. This ensures your images maintain their intended impact without distractions from unwanted light reflections.
Long-Term Optical Stability
NiSi ensures that the optical properties of this filter remain permanently stable and do not degrade over time. This long-term reliability guarantees consistent performance, maintaining clarity and quality for years.
