Nisi Athena FS ND 0.6 2-Stop Drop-In Filter camera filter

SKU CH-CZH4-20NZ9

Drop-in neutral-density filter darkens the image by two stops for slower shutter speeds and wider apertures on Athena lenses

  • Darkens images by two stops for motion control
  • Enables wider apertures for shallow depth of field
  • Full-spectrum neutrality preserves true-to-life colours
  • Nano coating reduces reflections and protects glass
  • Lightweight aluminium frame adds strength without bulk

Purpose-built for NiSi Athena lenses

The NiSi Athena FS ND 0.6 is a drop-in neutral-density filter made exclusively for NiSi Athena full-frame prime lenses that feature the integrated filter slot. It darkens the entire image by 2 stops, letting you lengthen exposure time or open the aperture without changing the lighting. The design targets cinematographers and photographers who need precise exposure control on this specific lens system.

Optical neutrality with protective coating

High-quality optical glass is treated with NiSi Optical Nano Coating to deliver full-spectrum neutrality, preserving authentic colour fidelity and clarity across the frame. The lightweight aluminium frame adds rigidity without noticeable bulk, so the filter seats securely in the drop-in slot and maintains consistent optical performance during normal shooting.

Drop-in convenience for creative flexibility

The drop-in format means the filter slides into the lens’ built-in slot, removing the need for front-thread adapters or matte-box trays. This lets you swap densities quickly when you want slower shutter speeds for motion blur or wider apertures for shallow depth of field, keeping the workflow fast and the optical path clean.

Questions about this item

How do I install the NiSi Athena FS ND 0.6 filter into the lens drop-in slot?

Slide the filter into the dedicated drop-in slot on the NiSi Athena lens until it clicks securely into place; the most common mistake is inserting it upside down, which prevents the latch from engaging.

What maintenance will the NiSi Optical Nano Coating on this filter require over time?

Clean the coating with a soft microfiber cloth and optical cleaning solution; avoid abrasive materials that can degrade the nano-layer and reduce its anti-reflective performance.

At what point does the 0.6 density limit exposure control under bright, sustained lighting?

The 2-stop reduction caps the maximum shutter-speed extension or aperture widening; in intense light you may reach the camera's minimum ISO or maximum shutter speed before achieving the desired effect.
