Hoya NDx400 52mm Filter Black

The Hoya NDx400 52mm Filter Black is a neutral density filter that reduces incoming light by 9 stops (NDx400), enabling safe imaging of extremely bright sources and allowing much longer exposure times for creative effects. Made from high-quality optical glass with a durable black frame, the filter also benefits from Hoya's HMC (Hoya Multi Coated) treatment to minimise surface reflections, reduce flare and ghosting, and preserve contrast and color balance.

Advantages

This NDx400 filter lowers light intensity to less than 1/500th of the original, permitting safe photography of solar eclipses and other ultra-bright light sources while preventing sensor overload. The HMC multi-coating reduces reflections and flare, maintaining sharp contrast and accurate colors. A robust black frame secures the optical glass and fits lenses with a 52mm filter thread for reliable everyday use.

Suitable for

• Photographing solar eclipses and very bright light sources
• Long-exposure daylight photography (e.g., smoothing water, motion blur removal)
• Landscape and outdoor photography requiring color fidelity and reduced glare
• Creative photography needing extremely slow shutter speeds

How to use

Attach the filter to the front of a lens with a 52mm filter thread by carefully screwing it until snug; avoid over-tightening. When photographing solar eclipses or other extremely bright sources, use appropriate viewing and camera precautions and confirm correct exposure settings before shooting. For long-exposure daylight shots, compose the frame and set a small aperture and low ISO, then use the extended shutter speed enabled by the NDx400 to achieve the desired motion blur or smoothing effects.

Usage recommendations

Do not look directly at the sun through the viewfinder without additional solar viewing protection. Use the NDx400 only with lenses it fits (52mm thread). To minimise vignetting on wide-angle lenses, check the filter and lens combination at the desired focal length. Store the filter in its case when not in use to protect the coatings and glass.
