The Hoya 58mm HD MKII IRND 8 Neutral Density 0.9 3-Stop Filter is a precise optical accessory for photographers and filmmakers who require exact exposure control. It reduces light transmission by three stops, equivalent to a density of 0.9, allowing for creative techniques such as long exposures and shallow depth of field in bright lighting conditions. With HOYA's ACCU-ND technology, it ensures consistent light reduction across the visible and infrared spectrum without color shifts, preserving image fidelity. The filter is constructed with a lightweight, precision-machined aluminum frame that minimizes light leaks and supports front filter threads for stacking additional accessories. Advanced multi-coatings with anti-reflective properties reduce stray light and ghosting, while a water-repellent and oil-repellent surface coating makes cleaning easier. With a diameter of 58 mm, it is compatible with lenses of the same thread size and is designed for durability and reliable performance in various shooting environments, making it suitable for landscape, portrait, and cinematic applications.
