Hoya HD Mk II IRND8 (0.9) 77mm Neutral Density Filter

The Hoya HD Mk II IRND8 (0.9) is a neutral density filter that reduces light to the equivalent of 3 stops. With ACCU-ND IR-cut technology, water and oil-repellent coating, and low-profile frame. Density 0.9, divides incoming light by 8 (3 stops). Neutral density (ND) filters are the most requested and essential type of photographic filter for several reasons. For photographers, ND filters mean precise control over the amount of light passing through the lens for better creative exposure control. For video creators, ND filters greatly assist in setting shutter speeds to match frame rates while maintaining depth of field. To create a beautiful blurred background, the HD Mk II IRND8 is the perfect density for creating a beautiful blurred background in typical portrait or daylight conditions easily achievable with fast f/1.2 or f/1.4 fixed-focus lenses at maximum aperture, but it requires a high shutter speed. Since some cameras come with a maximum shutter speed of 1/4000 sec. that would cause overexposure with such fast lenses, the photographer can still get proper exposure by controlling the shutter speed using the HD Mk II IRND8.
