Hoya HD MK II IRND64 (1.8) Filter 52mm

Hoya IR-ND Filter HD MK II ND64 (6stop) 52mm

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".

Key Features:

• Reduces light entering camera by 6 stops
• Create motion blur with moving objects
• ACCU-ND technology for an even light reduction throughout the visible and IR light spectrum
  to avoid any unintended color shifts due to IR pollution
• Anti-reflection multi-coating
• Water- and oil repellent properties for easy and stress-free cleaning
• Low-profile lightweight aluminum frame for minimum chance of vignetting
• For still and video

ACCU-IRND Technology

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.

Multi Coating / Water and Oil repellent

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.
