NiSi Cine Drop-In Filter FS ND16

NiSi Cine Drop-In Filter FS ND16 – 4-stop light reduction for NiSi ATHENA lenses

The NiSi Cine Drop-In Filter FS ND16 reduces incoming light by 4 stops, enabling slower shutter speeds and wider aperture use with NiSi ATHENA full-frame prime lenses that have a drop-in filter slot. It preserves colour fidelity and helps you achieve cinematic motion blur or shallow depth of field while keeping images neutral across the spectrum.

Designed for creative control

Use this drop-in ND to slow shutter speeds and capture controlled motion blur in moving subjects. Alternatively, open the aperture wider to isolate subjects with a softer, more cinematic background. In both cases, the filter gives you predictable exposure control without altering the natural colour of the scene.

Optical quality and coating

The filter uses high-quality optical glass and features NiSi Optical Nano Coating technology. As a result, it maintains full-spectrum neutrality so that your footage stays true-to-life. You get clarity and colour fidelity without the common colour shifts or distortions that can occur with lower-quality neutral density filters.

Construction and handling

The glass is housed in an aluminum frame that balances robustness with lightweight handling. This design supports regular field use while keeping the filter easy to install and remove from the lens drop-in slot. For transport and protection, the filter is supplied with a practical carry case so you can keep it safe between shoots.

Compatibility

This filter fits NiSi ATHENA full-frame prime lenses that include a drop-in filter slot. It integrates directly into the lens’ drop-in cavity, acting as an extension of the lens and ready to use whenever your creative needs call for neutral density control.
