Hoya Sq100 IRND1000 Neutral Density Filter (100x100mm, 10-Stop)

The 100 x 100mm square IRND1000 Neutral Density Filter from Hoya is a 10-stop neutral density filter for the Sq100 Filter Holder system. It features HOYA's exclusive ACCU-ND technology, which achieves equal reduction of the light in visible and IR spectrums. This added IR filtration eliminates issues with color shift in any shooting conditions, when compared to conventional ND filters.

Neutral density filters are important for filmmakers and photographers because they allow precise control over the amount of light passing through the lens. For filmmakers, this means shutter speeds that match the camera frame rate while maintaining creative depth-of-field control. Using a longer shutter speed makes it possible to increase blur to convey a sense of movement, or to dial in a video camera frame rate. Increased density also makes it possible to shoot using wider lens apertures, helping to isolate a subject from the background and increasing bokeh.
