NiSi Cine Drop-In Filter FS ND128

NiSi Cine Drop-In Filter FS ND128 – 7-stop ND for slower shutter speeds and wider apertures

The NiSi Cine Drop-In Filter FS ND128 darkens images by 7 stops, enabling filmmakers to use slower shutter speeds and wider apertures. This control over exposure lets you capture motion blur intentionally or achieve a shallower depth of field for more cinematic visuals.

Designed for Athena full-frame prime lenses

This filter fits the drop-in filter slot of NiSi ATHENA full-frame prime lenses. It sits snugly in the lens’ dedicated slot and becomes an integrated part of your optical chain during shoots. Consequently, it adapts to your creative needs without requiring changes to front-mounted filter systems.

Optical performance and neutrality

NiSi engineered the FS ND128 with high-quality optical glass to preserve image clarity. In addition, the filter features NiSi Optical Nano Coating technology that maintains full-spectrum neutrality. As a result, the filter keeps color fidelity and reduces the risk of color shifts so your footage remains true to life.

Build and portability

The drop-in element sits inside a lightweight yet robust aluminum frame, offering durability for field use while keeping handling practical. For transportation and protection, the filter comes with a convenient carry case so you can store and move it safely between locations.

Creative uses

By providing a fixed 7-stop reduction in exposure, the FS ND128 opens up creative possibilities. For example, you can intentionally blur motion to convey movement, or you can open the aperture to isolate subjects with shallow depth of field. In short, it helps you control exposure and aesthetics without changing ISO or relying on electronic shutter limits.
