NiSi Cine Filter FS ND 1.2 (4 Stop) for Athena PL-Mount Lenses

NiSi Cine Filter FS ND 1.2 (4 Stop) – Full Spectrum Rear PL Filter for ATHENA PL-Mount Lenses

The NiSi Cine Filter FS ND 1.2 (4 Stop) is a full spectrum neutral density rear PL filter made for NiSi ATHENA PL-mount lenses. It reduces incoming light by four stops, letting filmmakers use slower shutter speeds and wider apertures even in bright conditions. The filter mounts at the rear of ATHENA PL lenses and aims to preserve color fidelity while giving precise exposure control.

What this filter does

This FS ND filter controls exposure by reducing light entering the lens by a precise amount (4 stops for the 1.2 version). As a result, you can achieve motion blur in moving subjects or increase depth of field control by opening the aperture without overexposing the image. It works across the visible spectrum to avoid unwanted color shifts, so footage needs minimal color correction in post.

Key features

• Superior light management: The FS ND 1.2 reduces light by four stops, enabling slower shutter speeds and larger apertures for cinematic motion blur and refined depth-of-field control under bright lighting.
• Full spectrum capability: The filter is designed to maintain color fidelity across the spectrum, so it minimizes color shifts and helps you capture true-to-life colors that require less post-processing.
• Custom-fit for ATHENA PL lenses: This filter is rear-mounted and tailored specifically for NiSi ATHENA PL mount lenses to maintain alignment and image quality when installed.
• Included suction cap tool: The package includes a suction-cap style tool that lets you remove and install the rear filter directly on the lens without leaving fingerprints, allowing faster and cleaner filter changes on set.
• Built to last: The filter is crafted from premium optical materials and features a Multi Ti Nano coating with low reflection and anti-scratch resistance to withstand professional use.

FAQ

Question: Is this filter compatible with all NiSi ATHENA PL-mount lenses?
Answer: Yes. The filter is designed specifically as a rear PL filter for NiSi ATHENA PL-mount lenses to ensure proper fit and maintained image alignment.

Question: Will the filter cause color shifts that require heavy color correction?
Answer: The FS ND is built for full spectrum performance and is intended to minimize color shifts so you should need minimal color correction in post.

Question: Can I achieve motion blur or shallower depth of field with this filter?
Answer: Yes. By reducing light by four stops, the 1.2 version lets you use slower shutter speeds for motion blur and wider apertures for shallower depth of field while avoiding overexposure.

Question: How do I change the filter without touching the glass?
Answer: The included suction-cap tool allows you to remove and install the rear-mounted filter directly on the lens, helping prevent fingerprints and speeding up filter swaps on set.

Question: Is the filter durable enough for professional use?
Answer: The filter uses premium optical materials and a Multi Ti Nano coating that provides low reflection and anti-scratch resistance, designed to meet the demands of professional workflows.
