K&F Concept 4x5.65" Square Cinema ND1.2 (4 Stops) ND16 Neutral Density Filter Optical Glass

The K&F Concept 4x5.65" Square ND1.2 (4 Stops) ND16 Neutral Density Filter is designed for professional cinema use, compatible with Tilta, SmallRig Matte Boxes, Mini Matte Boxes, and Filter Frames. This filter reduces light by 4 stops (ND16, 1.2 density), allowing greater control over shutter speed and aperture to prevent overexposure and balance image exposure.

Key Features:
* **Matte Box Compatibility:** Specifically designed for mounting on matte boxes, fitting various camera lens systems.
* **High-Definition Optical Glass:** Made from imported optical glass, double-sides polished to ensure high clarity without compromising image quality or adding color cast, ideal for 4K and 8K video recording.
* **Ultra-Low Reflectivity:** Features 0.2% ultra-low reflectivity to effectively minimize lens reflection and vignetting, resulting in clearer images with enhanced contrast and detail.
* **28 Multi-Layer Coatings:** Both sides of the glass are treated with nanometer coatings, making the filter scratch-resistant, waterproof, oil-proof, and fingerprint-resistant for durable performance.
* **Dimensions:** Measures 4" x 5.65" (10.16 x 14.35cm).

Note: This square ND filter is not designed to be screwed directly onto a lens; it is used with a matte box, making it versatile for lenses of various focal lengths.
