Hoya 49mm HD Mk II IR ND 1000x (10 Stop) Neutral Density Filter

The HD MKII IR ND1000 Neutral Density Filter from Hoya is a 10-stop neutral density filter that 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 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 framerate. Increased density also makes it possible to shoot using wider lens apertures, helping to isolate a subject from the background and increasing bokeh.
