This high-quality, dual-filter kit is designed to adapt to an array of lighting conditions, ensuring that your photography is never compromised by the intensity of your environment. Crafted from Pure High Definition Optical glass with an impressive 18-layer multi-coating, these filters promise an exceptional filmmaking experience. The meticulous coating process enhances image clarity by minimizing reflections and ghosting, while also offering robust protection against the elements. Each side of the glass element is fortified with a coating that is waterproof, dustproof, scratchproof, and oilproof, empowering you to confidently face any adventure. The innovative design features a built-in hard stop, providing a threaded variable ND that eliminates the risk of cross-polarization and ensures zero vignetting for lenses 16mm and above. This feature is particularly effective in maintaining image quality and consistency during shoots. Functionally, the filters offer a range of density levels to suit your needs. The 2 to 5 stop filter, equivalent to ND4-ND32, is perfectly suited for standard day conditions, from overcast to typical sunny days. Meanwhile, the 6 to 9 stop filter, equivalent to ND64-ND512, is ideal for very bright conditions, from normal sunny days to the most intense sunlight.
