The Benro Master Glass Filter 150x170mm Reverse-Edged GND8 (0.9) is a graduated neutral density filter designed for professional photography, providing a 3-stop light reduction to balance exposure in high-contrast scenes. It features a reverse gradient that transitions smoothly from dense to clear, making it ideal for sunrise or sunset photography, where the horizon is brightest. The filter incorporates an advanced NANO WMC coating for water, oil, and scratch resistance, making cleaning easier, as well as a ULCA multi-coating to minimize lens reflections and chromatic aberration for improved image clarity. An IR CUT coating reduces infrared light pollution and maintains color fidelity and deep blacks in images. With dimensions of 150x170mm, the filter is compatible with various lens sizes and supports an average light transmission of over 99.0% in the wavelength range of 420-680nm, ensuring accurate color reproduction. Made from high-quality glass, this filter is designed for durability and reliability under demanding photographic conditions, making it suitable for landscape, seascape, and architectural photography, where precise exposure control is essential.
