NiSi Cine Drop-In Filter FS ND2

NiSi Cine Drop-In Filter FS ND2 – 1-Stop Neutral Density for NiSi Athena Lenses

The NiSi Cine Drop-In Filter FS ND2 reduces light by one stop to enable slower shutter speeds and wider apertures when used with compatible NiSi Athena lenses. It gives filmmakers the creative control to capture motion blur, smooth exposure in bright conditions, and separate subjects with shallow depth of field.

How this filter helps your filmmaking

Use the ND2 when you want to slow shutter speed for cinematic motion blur or open the aperture for a softer background while maintaining correct exposure. Because it darkens the image by exactly one stop, you can predictably adjust exposure settings and achieve consistent results across takes.

Optical performance and coating

The filter uses high-quality optical glass combined with NiSi Optical Nano Coating technology. As a result, it delivers full-spectrum neutrality so your images retain authentic color fidelity and clarity. In practice, this means you should see minimal color shifts and consistent, true-to-life tones in your footage.

Design and construction

NiSi crafts the filter from high-grade optical glass and houses it in a lightweight yet robust aluminum frame. This construction balances optical quality with durability for field use. Moreover, the filter fits snugly into the Athena lenses’ drop-in filter slot, so it becomes an integrated part of the lens system rather than an add-on.

Portability and protection

For convenience and safe transport, the NiSi ATHENA Drop-In Filters come with a carry case. The case helps protect the filter between shoots and makes it simple to keep the accessory within reach when you travel or move between setups.
