Hoya HD Mk II IRND64 Neutral Density Filter 49mm

Neutral Density (ND) Filters

Neutral density (ND) filters are essential photographic tools that provide precise control over the amount of light entering the lens, enabling greater creative control of exposure. For video creators, ND filters allow shutter speeds to be matched to frame rates while maintaining depth of field.

HD Mk II IRND64 for Motion Blur and Flowing Effects

The HD Mk II IRND64 filter is designed to blur moving objects and visualize motion, such as flowing water, waves, or moving people. Without an ND filter, standard camera settings render motion as still in images. While reducing aperture to f/16 or f/22 can create a flowing effect, it may cause diffraction that degrades image resolution. Additionally, cameras with a minimum ISO of 200 and fast prime lenses may not achieve sufficiently slow shutter speeds to capture motion blur. Using the HD Mk II IRND64 allows shooting at optimal apertures to avoid diffraction and reduces exposure to shutter speeds that express flowing movement effectively.

Advanced IRND Technology for Uniform Light Reduction

HOYA's ACCU-ND technology ensures even light reduction across the visible spectrum and into the infrared range, preventing infrared light leakage that can cause color shifts. This technology positions the HD Mk II IRND series as a market leader in high-quality neutral density filters.

Water- and Oil-Repellent Anti-Reflection Multi-Coating

The filter features a multi-coating that minimizes reflections and includes water- and oil-repellent properties, facilitating easy and stress-free cleaning.

HD Low-Profile Frame Design

The ultra-thin, lightweight aluminum frame reduces vignetting when used with wide-angle lenses and supports stacking with other filters via an integrated front filter thread.
