NiSi Cine Filter FS ND 0.3 (1 Stop) for Athena PL-Mount Lenses

NiSi Cine Filter FS ND 0.3 (1 Stop) for Athena PL-Mount Lenses – Full Spectrum rear ND for precise light control

Use the NiSi ATHENA Full Spectrum FS ND Rear PL Filter to manage exposure and preserve color fidelity when shooting with ATHENA PL mount lenses. This rear-mounted neutral density (ND) filter reduces light by a precise amount, helping filmmakers achieve slower shutter speeds or wider apertures without compromising image color. It is engineered specifically for NiSi ATHENA PL Mount Lenses to ensure proper fit and alignment.

Key features

• Superior light management: The FS ND filter reduces the amount of light entering your lens by precise stops. Consequently, you can use slower shutter speeds or larger apertures to create cinematic motion blur and control depth of field, even in bright shooting conditions.
• Full spectrum capability: The filter is designed to maintain fidelity across the color spectrum. As a result, it prevents color shift and yields true-to-life results that require minimal correction in post-production.
• Custom-fit for ATHENA PL lenses: This is a rear-mounted filter specifically tailored for NiSi ATHENA PL Mount Lenses. Therefore, it aligns correctly with the optical path and preserves the intended image quality of those lenses.
• Included suction cap tool: The filter ships with a tool that uses a suction cap design. This tool enables quick and secure filter changes directly on the lens while minimizing the risk of leaving fingerprints on the glass, so your lens remains clean during swaps.
• Built to last: NiSi manufactures the filter from premium optical materials and applies a Multi Ti Nano coating. This coating offers low reflection and anti-scratch resistance, which helps the filter withstand the demands of professional use.

How this filter supports filmmaking workflows

Filmmakers often need predictable exposure control and consistent color across takes. By reducing incoming light in precise stops, this FS ND filter gives you the flexibility to maintain shutter speed or aperture choices that support a specific cinematic look. Additionally, because it is full spectrum and rear-mounted for Athena PL lenses, you can rely on consistent color rendering and correct alignment with your lens’ optical path.
