This professional-grade filter measures 100 x 150mm and offers a 4-stop light reduction, making it an essential tool for landscape and seascape photographers who require balanced exposures during sunrise or sunset when the light contrast is most challenging.

Crafted with a 2mm thickness, this versatile filter is compatible with Sirui's own filter holders as well as other brands' 100mm systems, ensuring a seamless fit for a variety of shooting setups. The Sirui Filter Holder (NDH-001, Spec:100mm) is specifically designed to accommodate this GND filter, allowing attachment to full-frame camera lenses as wide as 16mm and filter diameters up to 82mm without vignetting.

The filter boasts precision-ground and polished German-manufactured Schott Plate Glass B270, renowned for its high resolution and optical flatness, ensuring that your images remain sharp and distortion-free. The exclusive nano lens coating process applied to the filter surface features multiple ultra-thin layers, guaranteeing a uniform reduction of light from edge to edge. This advanced coating technology maximizes light transmission while minimizing reflections and ensuring precise color rendition.

Durability and maintenance are also taken into account with a protective coating that is waterproof, oil-resistant, scratch-resistant, anti-reflective, and anti-static. This makes the filter easy to clean and provides superior protection against the elements and everyday wear and tear.

Available in Soft Graduated, Hard Graduated, and Reverse Graduated options, this filter caters to a variety of photographic needs. The Reverse Graduated version, in particular, is expertly designed to darken the brightest parts of the scene near the horizon line while allowing for a clearer transition to the darker sky above, resulting in perfectly balanced exposures.
