The Hoya HMC NDX400 filter is designed for photographers who need extreme light reduction for long exposure work in bright conditions. With an optical density of 2.7, it reduces incoming light by 9 stops, making it possible to use slower shutter speeds or wider apertures while maintaining creative control over exposure.

Built with high-quality optical glass, the Hoya HMC NDX400 filter helps preserve image clarity and neutral colour balance. Its three-layer HMC multi-coating reduces internal reflections, flare and ghosting while providing approximately 98–99% light transmission. A durable aluminium filter ring securely houses the glass.

This 9-stop neutral density filter is especially useful for photographing flowing waterfalls, rivers, clouds and moving subjects with a smooth motion effect. It also helps create shallow depth of field in bright daylight by allowing wider aperture settings without overexposing the image.

For landscape photographers, the HMC long exposure filter offers greater flexibility when capturing scenes in sunlight. Videographers can also use this high-density ND camera filter to manage exposure in demanding lighting conditions. It is a practical ND filter for landscape photography.

Choose the Hoya HMC NDX400 filter for controlled long exposures, reduced light intake and optical performance. Available in multiple thread sizes to fit compatible camera lenses.
