Hoya HD Mk II IRND64 Neutral Density Filter 77mm

Neutral Density (ND) Filters

Neutral density (ND) filters provide precise control over the amount of light entering the lens, enabling greater creative exposure control for photographers and allowing video creators to maintain shutter speeds that match frame rates while preserving depth of field.

HD Mk II IRND64 for Motion Blur and Flowing Effects

The HD Mk II IRND64 filter is ideal for motion control and blurring moving subjects such as flowing water, waves, or people. Without an ND filter, movement appears frozen in images. While reducing aperture to f/16 or f/22 can create a flowing effect, it risks diffraction that degrades image resolution. Cameras with a minimum ISO of 200 and fast prime lenses may not achieve slow enough shutter speeds without this filter. The HD Mk II IRND64 allows shooting at optimal apertures to avoid diffraction and reduces exposure to shutter speeds that capture natural motion flow.

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 leaks that cause color shifts. This technology sets the HD Mk II IRND series as a market leader in high-quality IR 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

Constructed with an ultra-thin, lightweight, and precisely crafted aluminum frame, the HD Mk II IRND64 reduces vignetting when used with wide-angle lenses. The integrated front filter thread allows for convenient stacking of additional filters.
