The Benro Master Series Hard-Edged Graduated ND Filter GND16 1.2 is a professional optical filter designed for landscape and architectural photography. This filter features a hard transition with a density of 1.2 (4-stop reduction), gradually darkening the image from top to bottom, making it ideal for balancing exposure between bright skies and darker foregrounds. The advanced NANO WMC coating technology provides exceptional scratch resistance and repels water and oil, making cleaning easier. The ULCA multi-coating significantly reduces stray light and chromatic aberration, with over 99.0% average light transmission in the visible spectrum from 420-680 nm. An additional IR CUT coating minimizes infrared pollution for accurate color reproduction. The filter delivers smooth, naturally appearing gradient transitions without visible lines or color casts. Made from high-quality optical glass, this filter maintains image sharpness and clarity while providing reliable exposure control. The hard-edge design is particularly effective for scenes with straight horizon lines, such as architectural photography or landscapes with defined horizons. With a width of 150 mm and a height of 170 mm, this rectangular filter is compatible with standard filter holder systems. Its robust construction ensures durability for professional use in various environmental conditions. This filter is part of the Benro Master Series, which represents the premium optical filter line for demanding photographic applications where optical performance and build quality are crucial.
