The Benro Master Glass Filter 100x150mm Hard-Edged GND8 (0.9) is a professional graduated neutral density filter specifically designed for landscape photography. This 100x150mm filter features a hard transition with a 3-stop light reduction (ND8/0.9 density), effectively balancing exposure between bright skies and darker foregrounds. Made from high-quality optical glass, the filter incorporates advanced NANO WMC coating technology that repels water and oil, resists scratches, and simplifies cleaning. The ULCA multi-coating system reduces stray light and chromatic aberration, achieving over 99.0% light transmission in the wavelength range of 420-680nm for enhanced image sharpness and color accuracy. An integrated IR CUT coating minimizes infrared pollution to prevent unwanted color casts. The hard edge transition allows for precise exposure control in scenes with distinct horizon lines. This durable filter maintains optical performance even under heavy use, making it ideal for professional photographers who require reliable exposure control in challenging lighting conditions. The 100x150mm rectangular format is compatible with standard filter holder systems, providing practical functionality for outdoor photography applications where a natural-looking exposure balance is essential.
