The Hoya 82mm ProND32 Filter is a solid neutral density filter that enables a 5-stop increase in exposure. This creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By slowing your exposure time or increasing your aperture, you are able to control the depth of field and convey movement more easily. This filter employs Hoya's metallic ACCU-ND coating on both sides of the substrate to create the neutral density effect and ensure maintained colour neutrality between filter grades. It is constructed from high-quality clear optical glass for notable image clarity and is set within a durable one-piece aluminium filter ring.
