NiSi Cine Drop-In Filter ND16/Polarizer

NiSi Cine Drop-In Filter ND16/Polarizer – 4-stop ND with polarizer for NiSi ATHENA lenses

This NiSi Cine Drop-In Filter ND16/Polarizer is designed specifically for NiSi ATHENA full-frame prime lenses that feature a drop-in filter slot. It darkens the image by four stops, allowing you to use slower shutter speeds and wider apertures when you need them. At the same time, the polarizer reduces reflections and glare from non-metallic surfaces, helping you capture clearer skies and richer foliage.

How it improves your image

Use this combined ND16 and polarizer to control exposure and manage reflections without changing lens front elements. Consequently, you can create motion blur with slower shutter speeds or achieve a shallower depth of field with wider apertures. Furthermore, the polarizing effect filters light that has become polarized by reflection from non-metallic surfaces, which reduces glare and increases perceived saturation in skies and foliage.

Construction and optical quality

The filter uses high-quality optical glass and features NiSi Optical Nano Coating technology to deliver full-spectrum neutrality. As a result, the filter preserves true-to-life color fidelity and clarity, minimizing color shifts or distortions. Additionally, the glass is mounted in a lightweight yet robust aluminum frame built to withstand field use.

Practical design and portability

The NiSi Cine Drop-In Filter fits snugly into the Athena lenses’ drop-in filter slot, functioning as an integrated extension of the lens. For convenience and transport, the filter comes with a dedicated carry case so you can protect and move it easily between shoots.

Key features

• Designed for use with NiSi Athena full-frame prime lenses featuring a drop-in filter slot — fits the Athena drop-in slot for a secure, integrated placement.
• Darkens the overall image by 4 stop — ND16 provides a four-stop reduction in light to help you manage exposure in bright conditions.
• Enables slower shutter speed utilization — use longer exposures to capture motion blur and creative effects.
• Facilitates wider aperture settings — maintain shallower depth of field in bright environments without overexposing.
• Delivers full-spectrum neutrality for authentic, true-to-life outcomes — NiSi’s optical approach keeps color reproduction accurate.
• Enhanced with NiSi Optical Nano Coating technology — the coating helps maintain clarity and reduces unwanted optical artifacts.
• Crafted from high-quality optical glass — the optical glass maintains image sharpness and detail.
• Encased in a lightweight yet robust aluminum frame — built to endure field use while remaining easy to handle.
• Comes with a convenient carry case for easy transportation — protects the filter between shoots and simplifies storage.

Typical use cases

1. Slow shutter cinematography: create smooth motion blur for water, traffic, or moving subjects by reducing available light.
2. Shallow depth of field in bright light: open your aperture for subject separation while avoiding overexposure.
3. Reflection control and color enhancement: reduce glare on non-metallic surfaces and increase saturation in skies and foliage for more vivid imagery.

Compatibility

This filter is compatible with NiSi ATHENA Full Frame Primes that include a drop-in filter slot. It is intended to be used specifically with those Athena lenses and fits into their dedicated drop-in slot for a secure and integrated workflow.

Frequently Asked Questions

question: Which lenses is this filter made for?
Answer: The NiSi Cine Drop-In Filter ND16/Polarizer is made for NiSi ATHENA full-frame prime lenses that have a drop-in filter slot. It is designed to fit that specific slot and integrate with the Athena lens system.

question: How much light does the ND16 element block?
Answer: The ND16 element darkens the image by four stops, allowing you to use slower shutter speeds or wider apertures in brighter conditions.

question: What does the polarizer do on this filter?
Answer: The polarizer filters out light that has become polarized by reflection from non-metallic surfaces. This reduces glare and reflections while increasing the apparent saturation of skies and foliage.

question: Will this filter change my color balance or image neutrality?
Answer: The filter features NiSi Optical Nano Coating technology and full-spectrum neutrality to preserve true-to-life color fidelity and minimize color shifts or distortions.

question: What materials and protection are included?
Answer: The optical element is made from high-quality optical glass housed in a lightweight but robust aluminum frame. The product also comes with a carry case to protect the filter during transport and storage.

question: How does the filter mount in the lens?
Answer: The filter fits snugly into the Athena lens drop-in filter slot, making it an integrated part of the lens setup and ensuring a secure fit for field use.
