NiSi Cine Filter Explosion Proof / True Protector LP13110 – Shatterproof Protection for Cooke S4i / 5i / S6i / S7A (Big)

This NiSi Cine Explosion Proof / True Protector circular filter provides professional, shatterproof protection for cine lenses. It acts as a robust lens guard while preserving image quality. Use it whenever you need impact-resistant protection on Cooke lenses listed below.

Key features

• Double-sided waterproof and anti-reflective coating with no effect on image quality
• Made of Water White Glass Filter with Shatter-Proof Coating and No loss of sharpness
• Anti-Reflective, No Glare

These features combine to protect the front element from impacts, splashes and stray reflections while maintaining the original optical performance of the lens. The double-sided coatings help reduce reflections from either direction, and the shatter-proof treatment prevents glass fragments from scattering if the filter takes a heavy hit.

Compatibility

This filter is especially made for Cooke lenses and is compatible with the following models as listed:

• Cooke S4i 180mm, 300mm
• Cooke 5i 135mm
• Cooke Anamorphic/i 25mm, 65mm (macro), 300mm, 35-140mm

Mounting and use

Customized Filter Thread! The filter uses a customized thread to match the intended Cooke lenses. You can use it with a lens cap or mount it in a matte box, depending on your workflow and protection needs. Install the filter as you would any circular protector, ensuring the thread engages cleanly to avoid cross-threading.

Practical benefits on set

On busy sets, this filter provides immediate front-element protection without altering the lens’ rendering. It helps guard against accidental knocks, dust and moisture while keeping reflections and glare under control. Because the filter is designed to avoid image-quality loss, you can leave it in place during shooting when protection is required.

Care and handling

Handle the filter carefully when attaching or removing it. The waterproof and anti-reflective coatings help with cleaning, but use appropriate lens-cleaning materials to avoid scratches. Store the filter with a cap or in a protective case when not in use to preserve the coatings and shatter-proof treatment.
