Neutral density (ND) filters are the most demanded and essential type of photographic filters because of several reasons. For photographers ND filters mean precise control of the amount of light passing through the lens for greater creative control over exposure. For video content creators ND filters help immensely to set shutter speeds to match the frame-rate while maintaining the depth-of-field of the footage.
The HD Mk II IRND64 is perfect for performing motion control or blurring objects and is therefore used to render movement of moving objects such as water flow, wave motion or moving people. Without an ND filter and with standard camera settings the movement would appear "still" on the final image. A flowing effect can be achieved through reducing the aperture to f/16 or f/22, but this may cause diffraction that makes the resolution and overall depiction poor. Also, when shooting with fast prime lenses and cameras that have ISO200 as their lowest sensitivity, it might not be possible to reduce the exposure enough to achieve a shutter speed that causes the "water flowing" effect. However, by using the HD Mk II IRND64 filter, it is possible to shoot at a proper f/ value to avoid "diffraction", and it is possible to lower the exposure to a necessary shutter speed value that can express the movement as "flowing".

HOYA applies its signature ACCU-ND technology to the HD Mk II IRND series, guaranteeing an even light reduction throughout the visible light spectrum and up into the higher IR spectrum. This means that there is no leak from the infrared band of the light spectrum, guaranteeing that the image does not undergo any negative affect from color shifts.
ACCU-ND is a benchmark for IR ND technology and makes the HOYA HD Mk II IRND series a market leader for high quality ND filters.

The HD MK II IRND series applies an anti-reflection multi-coating that reduces the chance of any reflections caused by the filter. The coating also comes with water- and oil repellent features which makes cleaning the filter easy and stress free.
The HD Mk II IRND series uses an ultra-thin lightweight, precisely crafted aluminum frame, reducing the chance of vignetting immensely when using the filter with wide-angle lenses. It is also very useful when stacking filters, which can be done thanks to the integrated front filter thread.
