Neutral density camera filter Hoya NDx400 49mm

The Hoya NDx400 49mm neutral density camera filter reduces incoming light by 9 stops (approximately to less than 1/500th of the original intensity), enabling safe photography of extremely bright sources and very long exposure times for creative effects. Made from optical glass with a black frame and Hoya's HMC (Hoya Multi Coated) treatment, the filter is designed to minimise reflections and preserve contrast and colour balance.

Advantages

This NDx400 filter provides a significant light reduction of 9 stops for safe imaging of solar eclipses and other ultra-bright light sources, and for achieving super slow shutter speeds in daylight. Hoya HMC multi-coating reduces surface reflections, flare and ghosting while maintaining high light transmission and accurate colours. The 49mm size and durable black frame ensure reliable mounting and compatibility with lenses of the matching thread.

Suitable for

• Photographing solar eclipses and bright light sources safely
• Long exposure landscape photography (smooth water, cloud motion)
• Creative motion blur and subject disappearance in daylight
• Use with lenses that accept 49mm screw-in filters

How to use

Screw the filter onto the front of a lens with a 49mm thread until secure. For photographing solar eclipses or other very bright sources, confirm correct attachment and use recommended solar-viewing precautions for equipment and exposure settings. For long exposures in daylight, compose and focus before attaching the filter if possible, then set the desired shutter speed and tripod-stabilise the camera to avoid motion blur from the camera itself. Check histogram and preview images to adjust exposure as needed.

Usage recommendations

Use a sturdy tripod and remote shutter release or camera timer for long exposures. Avoid stacking multiple filters to reduce potential vignetting and added reflections. If capturing solar events, follow established safety guidelines for sensor and eye protection and use only filters specified for direct-sun viewing.
