The HOYA HD Mk II IRND FILTER KIT includes the three premium IRND filters HD Mk II IRND 8, 64 and 1000. As these densities allow photographers to create all possible effects of ND filters, such as motion blur, flowing effect and greater creative control over exposure, it is the perfect all-around kit that contains all essential and most popular ND filters for photography.
That makes the kit perfect for both amateur and professional photographers who want to fully make use of ND filters in all kinds of situations just as much as those who are not sure which ND filter is best for their vision and hence want to try out several densities.
The HD Mk II IRND8 is the perfect density for creating a beautiful blurred background in portrait or typical daylight conditions that is easily obtained with f/1.2 or f/1.4 fast prime lenses at maximum aperture but that requires a high shutter speed. As some cameras come with a maximum shutter speed of 1/4000 sec. that would cause over-exposure with such fast lenses, the photographer can still achieve an appropriate exposure by controlling the shutter speed though using the HD Mk II IRND8 filter.
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".
The HD Mk II IRND1000 is perfect for shooting "imaginary landscapes" or "another world" style images. With a density of 1000 you can easily make a person "disappear" from a cityscape shot, shoot in very long exposure under daytime conditions, or take time lapse videos of moving objects or people to create a movie of fascinating fast streams of movement. Combining ND1000 with the ND64 gives a density of ND64000 that is suitable for directly shooting the sun, e.g., during a solar eclipse, without overexposure and solid colors, while keeping details such as black spots.
IRND technology for even light reduction throughout the visible and IR light spectrum
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.
Color shift issue due to IR pollution.
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.
