HOYA HD Sq100 IRND8 (0.9)

Hoya Sq100 neutral density filter that reduces the light to an equivalent of 3 f-stops.

The Hoya Sq100 Square Filter system offers the premium HD square filter series for long exposure shots. Incorporating the newest state of the art technology, the HD Sq100 IRND8 filter is a light density IRND filter. It is generally used to lower the shutter speed during photo shoots on a bright sunny day for a motion effect. The filter also allows the photographer to reduce the depth of field in very bright light settings or to use a wider aperture to stay below the diffraction limit – especially when using fast lenses like F1.4 or F1.2 for a soft and beautiful bokeh.

Made from toughened glass, the HD Sq100 is designed to endure harsh conditions during travel and adventure. The IRND nano coating for both sides of the clear optical filter glass does not only remove IR contamination, but also creates a truly neutral color balance through its applied ACCU-ND technology. This prevents any noticeable color cast to your images. Additionally, its water repellent and anti-reflection coating drastically minimizes the risk of random light reflections while increasing the light transmittance.

The filter glass is made of 2mm thick, toughened optical glass that provides a four-times stronger durability than common filter glass, making the filter highly recommended for usage even in extreme shooting conditions.

KEY FEATURES:
- HD toughened optical glass is 4 times stronger than commonly used filter glass
- IRND nano coating using ACCU-ND technology minimizes the influence of the infrared spectrum and provides a balanced color presentation
- anti-reflection coating minimizes unwanted glare and the risk of random reflections
- the water-repellent finish increases resistance to stains and grease, the filter is easier to clean
