NiSi Cine Filter FS ND 0.9 (3 Stop) for Athena PL-Mount Lenses

The NiSi Cine FS ND 0.9 filter mounts at the rear of NiSi ATHENA PL-mount lenses. It reduces the light entering the lens by 3 stops, allowing slower shutter speeds and wider apertures in bright conditions for motion blur and depth of field control.

The full-spectrum design maintains colour fidelity without colour shifts, reducing the need for colour correction in post-processing. The filter is made from optical materials and has a Multi Ti Nano coating for low reflection and scratch resistance.

A suction-cap tool is included for quick filter changes directly on the lens without leaving fingerprints.
