HOYA HD Sq100 IRND8 (0.9) GRAD-S is a gradual neutral density filter with soft edge, made with high quality optical glass. It allows you to obtain a uniform exposure when capturing contrasting landscapes in full or setting sun. In the darkest spot, it lowers the image brightness by 3 f-stops, while helping to reduce information loss in overexposed areas of the image. It is fully compatible with the HOYA holder for the Sq100 system.

When photographing landscapes, the scenery is not always flat and uniform, and the horizon rarely appears to be a straight line. Most often they are multi-level, varied views with many details. In such situations, HOYA Sq100 filters will become an indispensable tool that will allow the photographer to draw the true, raw beauty of nature in the photo. Their elongated shape allows you to move them up and down on the handle, and thus precisely adjust the position to the frame. This solution gives much more freedom in operation than classic round filters.
The optical glass that was used to make the Sq100 series filters had been chemically reinforced to withstand the harsh conditions of travel and hiking. Despite their 2-millimeter thickness, they are four times more resistant to minor injuries than ordinary glass, found in cheaper filters made by other brands. You can use them without fear of them breaking, even during difficult journeys and extreme adventures in nature.

The Sq100 series filters are covered with many layers of special coatings in order to achieve the appropriate properties necessary to take stunning photos. The most important of these - IRND - effectively prevents and surpresses color casts due to increased exposure lenghts to ensure neutral color balance and a natural look. The ACCU-ND anti-reflective coating drastically minimizes the risk of accidental reflections while increasing light transmittance. Thanks to the hydrophobic layer, water droplets do not stay on its surface and drip off it quickly, leaving no streaks and stains behind.
