Hoya 77mm NDx400 HMC Filter

The Hoya NDx400 HMC Filter is a high-performance neutral density filter designed for photographers who want maximum light reduction and creative long-exposure control in bright conditions.

With a 9-stop light reduction (2.7 optical density), this solid ND filter dramatically limits the amount of light entering the lens, allowing for extended exposure times even in daylight. It’s ideal for creating smooth, flowing water effects, motion blur in clouds, and reducing movement in busy scenes for a more artistic result.

Constructed from high-quality optical glass, the filter maintains image clarity and sharpness while preserving natural color balance. The three-layer HMC (Hoya Multi-Coating) helps reduce reflections, flare, and ghosting, ensuring improved contrast and cleaner images.

The filter is housed in a precision aluminum ring, offering durability while remaining lightweight and easy to handle in the field.

Reliable, durable, and optically refined, the Hoya NDx400 HMC Filter is an essential tool for photographers seeking long-exposure creativity, superior light control, and consistent image quality.

Product Features in Detail

The NDx400 has a 9-stop light reduction equal to a ND optical density of approx. 2.7.
Neutral density filters are designed to reduce the amount of light entering your camera lens and should not have any other effect on the image. Reducing the amount of light allows for the use of wider apertures or slower shutter speeds for creative and dramatic effect in bright lighting conditions.
* This filter is NOT suitable for solar photography. DO NOT look at the sun through this filter, eye damage will occur.

HMC (HOYA MULTI COATED)
These popular filters are renowned for their ability to minimise reflection at the filter surfaces which reduces flare and ghosting. The result is an average light transmission of over 97%, giving sharp contrast and well balanced color. HOYA HMC filters are recommended for enhancing the performance of today's multicoated lenses.
