The Benro Master Glass Filter 100x150mm Reverse-Edged GND8 (0.9) is a high-quality camera filter designed for professional photography applications. With its reverse-edged graduated neutral density filter design and a density of 0.9, it provides a smooth, naturally appearing gradient for exposure compensation in high-contrast scenes. The dimensions are 100 mm in width, 150 mm in height, and 2 mm in thickness. Made from premium optical glass, the filter ensures durability and clarity. Special coatings enhance performance: the NANO WMC coating repels water and oil for easy cleaning and scratch resistance, the ULCA multi-coating reduces stray light and chromatic aberration with an average light transmission of over 99.0% between 420 nm and 680 nm, and the IR CUT coating minimizes infrared pollution for accurate color reproduction. Weighing 95 g, the filter is compatible with standard filter holder systems and is ideal for landscape and architectural photography, where precise exposure control is essential. The reverse-edged design allows for optimal transition positioning during sunrise and sunset, delivering reliable results under various lighting conditions.
