This filter reduces the amount of light and allows for longer exposure time and therefore enables larger aperture settings.
Irix Edge Neutral Density filters (ND) are an essential tool for long exposure photography and depth of field manipulation. The ND32000 version has optical density of 4.5 and reduces incoming light by 15-stops, allowing to do 5-minute long exposure under sunny day (at ISO 100, f/16). Their additional waterproof and oil repellent NANO coating prevent from stains, fingerprints and enable using in extreme weather conditions. Their low-profile frames and knurled edges provide very good grip and functionality with aesthetic design which harmonizes with all Irix products.
