Neutral density camera filter Hoya NDx4 72mm

The Hoya NDx4 72mm Neutral Density Filter reduces incoming light by 2 stops, enabling longer exposures and wider apertures in bright conditions. Made from high-quality optical glass with a neutral grey tint, the filter preserves colour balance while providing reliable light attenuation for landscape, portrait and video work.

Advantages

The NDx4 filter allows photographers and videographers to use slower shutter speeds or larger apertures in strong light without changing color rendition. It is useful for creating motion blur effects, controlling depth of field in bright scenes, and reducing effective ISO for high-speed film or sensors. The 72mm thread size fits lenses with matching filter threads and the optical glass construction minimises image degradation.

Suitable for

• Landscape photography (waterfalls, seascapes, bright mountain scenes)
• Portraits in bright light to achieve shallow depth of field
• Creating motion blur (moving water, clouds, traffic)
• Video and cine cameras that require light reduction at fixed shutter speeds

How to use

Screw the filter onto a lens with a 72 mm thread before taking photos or recording video in bright conditions. Use the NDx4 to extend exposure time for motion blur effects or to open the aperture wider for a shallower depth of field. When using fast film or high ISO settings outdoors, attach the filter to reduce effective exposure and avoid overexposure. Ensure the filter is clean and free of smudges for best image quality.

Usage recommendations

For best results, combine the NDx4 with a tripod when using long exposures and check focus and composition before attaching the filter if you rely on lens viewfinder brightness. Store the filter in its protective case when not in use to avoid scratches.
