NiSi Cine Drop-In Filter FS ND64

NiSi Cine Drop-In Filter FS ND64 – 6-stop reduction for slower shutter speeds and wider apertures

The NiSi Cine Drop-In Filter FS ND64 reduces incoming light by 6 stops, giving you the ability to use slower shutter speeds and wider apertures. It fits directly into the drop-in slot of NiSi ATHENA full-frame prime lenses, so you can quickly change exposure characteristics without swapping external filters.

What this filter does for your images

Use this ND64 to darken the overall image, which lets you capture motion blur, create a shallower depth of field, or preserve highlight detail in bright conditions. Because the filter provides full-spectrum neutrality, it maintains true-to-life colors and avoids unwanted color shifts. In short, it helps you retain clarity and color fidelity while changing exposure settings for creative effect.

Optical quality and coating

The filter uses high-quality optical glass combined with NiSi Optical Nano Coating technology. As a result, it delivers consistent, neutral results across the visible spectrum. Therefore, you get cinematic outcomes that preserve your original color tone and image clarity, without introducing the typical distortions associated with lower-quality neutral density filters.

Build and durability

The ND64 element sits inside a lightweight but robust aluminum frame. This construction balances field durability with low added weight so the filter remains a practical option for on-location shooting. The design also ensures a snug fit inside the Athena lenses’ drop-in filter slot, making the filter effectively an extension of the lens rather than a loose accessory.

Portability and convenience

NiSi supplies the drop-in filter with a convenient carry case. Consequently, you can transport it safely and have it ready when inspiration strikes. The drop-in format also speeds up workflow by allowing you to change the filter without re-threading or removing lens accessories.

Compatibility

This filter is compatible with NiSi ATHENA Full Frame Prime lenses that feature a drop-in filter slot. Make sure your lens has the specific drop-in slot to guarantee a proper fit and reliable performance.
