The Hoya 62 mm HD MKII IRND 8 Neutral Density 0.9 3-Stop Filter is a professional optical filter for photographers and filmmakers who require precise light control. With Hoya's advanced ACCU-ND technology, this filter provides uniform light reduction across the visible and infrared spectrum to eliminate color shifts and ensure consistent results under various shooting conditions. The 3-stop light reduction (ND 0.9) allows for longer exposure times and shallower depth of field even in bright sunlight, while maintaining proper shutter speed synchronization for video applications. The filter features a flat, precision-machined aluminum frame with a 62 mm diameter and front filter threads for additional filter stacking, as well as effective light leak prevention during long exposures. A multi-layer anti-reflective coating minimizes stray light reflections, while a water-repellent and oil-repellent surface coating makes cleaning and maintenance easier. This filter is compatible with all lenses with 62 mm filter threads and is an essential tool for landscape photography, long exposures, and cinematic video production where precise exposure control is required.
