The H&Y K-Series 100 x 100mm ND16 HD MRC ND filter is a professional-grade neutral density filter designed for photographers and videographers seeking precise exposure control. With its 100 x 100mm standard square filter format, this filter offers compatibility with most professional filter holder systems. The ND16 designation indicates a filter density that reduces light transmission by 4 stops (optical density of 1.2), allowing for creative control over shutter speed and aperture settings in bright lighting conditions. Constructed with high-definition optical glass, this filter maintains exceptional image clarity and color fidelity while minimizing distortion and chromatic aberration. The multi-resistant coating (MRC) technology provides enhanced durability against scratches, moisture, dust, and fingerprints, ensuring long-term performance reliability. This filter is particularly useful for achieving motion blur effects in landscape photography, controlling depth of field in portrait work, and maintaining proper exposure in video recording scenarios. The neutral density properties ensure accurate color reproduction without introducing unwanted color casts. The 100mm square format allows for flexible positioning within filter holder systems and can be stacked with other filters for combined creative effects. The filter frame is precision-engineered for secure mounting and easy handling during filter changes. This professional accessory is designed for photographers working with DSLR, mirrorless, and cinema cameras who require reliable exposure control tools for their creative workflow.
