NiSi Cine Filter FS ND 2.4 (8 Stop) for Athena PL-Mount Lenses

NiSi Cine Filter FS ND 2.4 (8 Stop) for ATHENA PL-Mount Lenses – Full Spectrum ND for precise exposure control

Use the NiSi ATHENA Full Spectrum FS ND 2.4 (8 Stop) filter to control light and preserve color fidelity on ATHENA PL mount lenses. This rear-mounted Full Spectrum neutral density (ND) filter reduces incoming light by eight stops while maintaining true-to-life colors. It suits filmmakers who need accurate exposure control in bright conditions.

Key features

• Superior light management: The FS ND filter reduces light entering your lens by precise stops, enabling slower shutter speeds and larger apertures. This control helps achieve cinematic motion blur and improved depth of field control even in bright shooting environments.
• Full spectrum capability: The filter is designed to maintain fidelity across the color spectrum, preventing color shifts so you capture natural, true-to-life images that require minimal color correction in post-production.
• Custom-fit for ATHENA PL lenses: The filter mounts at the rear and is tailored specifically for NiSi ATHENA PL Mount lenses to maintain optimal alignment and image quality.
• Included suction cap tool: The package includes a tool with a suction cap design for quick, easy filter changes directly on the lens without leaving fingerprints.
• Built to last: The filter uses premium optical materials and a Multi Ti Nano coating that delivers low reflection and anti-scratch resistance suitable for professional use.

What this filter lets you do

With the FS ND 2.4 (8 Stop) installed, you can keep larger apertures to control depth of field while reducing shutter speed for smoother motion blur. Consequently, you maintain creative control over exposure and look when shooting in bright conditions. At the same time, the full spectrum design preserves color balance so your footage remains consistent and requires less corrective grading.

Compatibility and fit

This is a rear-mounted filter designed specifically for NiSi ATHENA PL Mount lenses. Because it fits the ATHENA PL lens design, it preserves lens alignment and image quality without requiring front-element accessories or adapters.

Construction and coating

The filter is constructed from premium optical materials and features a Multi Ti Nano coating. The coating reduces reflections and adds anti-scratch resistance, helping the filter stand up to professional use while maintaining image clarity.

Included items

• Suction cap tool for secure and clean handling during filter changes.

Available stops and densities

The NiSi Cine FS ND series is available in eight optical densities. The FS ND 2.4 corresponds to an 8-stop reduction. The full list of options is shown below.

Frequently asked questions

question: Will this filter change the color balance of my footage?
Answer: The NiSi FS ND is a Full Spectrum filter designed to maintain fidelity across the color spectrum, so it minimizes color shift and preserves natural color balance for easier post-production.

question: How does the suction cap tool help on set?
Answer: The included suction cap tool lets you remove and install the rear-mounted filter quickly and cleanly, reducing the risk of fingerprints on optical surfaces and speeding up filter changes during shoots.

question: Is this filter compatible with lenses other than ATHENA PL mounts?
Answer: This FS ND rear-mounted filter is tailored for NiSi ATHENA PL Mount lenses to maintain optimal alignment and image quality. For other lens systems, check compatibility or consult us for available alternatives.

question: What practical effects can I achieve with the 8-stop version?
Answer: The 2.4 (8-stop) density allows significantly slower shutter speeds and larger apertures in bright conditions, enabling pronounced motion blur and shallow depth of field while keeping exposure under control.

question: How durable is the filter for professional use?
Answer: The filter is built from premium optical materials and features a Multi Ti Nano coating that provides low reflection and anti-scratch resistance, making it suitable for demanding production environments.
