Neutral density camera filter Hoya NDx4 55mm

The Hoya NDx4 55mm Neutral Density filter reduces the amount of light entering the lens by 2 stops, enabling greater control over exposure and depth of field in bright conditions. Made of optical glass with a black finish, this 55mm ND filter maintains colour balance while permitting longer shutter speeds or wider apertures for creative effects such as motion blur and subject separation.

Advantages

The NDx4 filter lowers exposure by two stops without altering colour balance, is compatible with 55mm lenses, and is constructed from high-quality optical glass for reliable image quality and durability. It allows photographers and videographers to use slower shutter speeds or larger apertures in bright light and helps prevent overexposure when filming with fixed-shutter video cameras.

Suitable for

• Long exposure photography (waterfalls, rivers, clouds)
• Portraits where shallow depth of field is desired in bright light
• Outdoor shooting with high-speed film or high ISO settings
• Video and cine cameras that require reduced light for correct exposure

How to use

Screw the Hoya NDx4 55mm filter onto the front thread of a compatible lens and check that the filter is clean and free of fingerprints. In bright conditions, use the filter to lengthen the required shutter speed for motion blur effects or to open the aperture for a shallower depth of field. When filming with cameras that have a fixed shutter speed, fit the filter to avoid overexposure in very bright scenes such as snow or sand.

Usage recommendations

For best results, combine the NDx4 filter with a tripod when using slow shutter speeds, and verify exposure using a light meter or camera histogram. Clean the filter with a suitable lens cloth before use and store it in a protective case to prevent scratches.
