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.
Building on the success and history of the HOYA HD series, this series is especially designed for professionals who want to take their photography to the next level.
