The Hoya Prond Ex 1000 67mm filter reduces the amount of light passing through the lens by 10 stops. When shooting videos outdoors, it facilitates shutter speed adjustments to match the frame rate, maintaining the desired depth of field. Very useful when capturing moving subjects, it allows motion blur, providing a more cinematic feel to the image. In photography applications, it makes it easier to use longer exposures or achieve a shallow depth of field in bright sunlight.

The ProND EX 1000 filter employs Hoya's ACCU-ND technology, which prevents color shift and maintains consistent image quality. This technology ensures equal light reduction across both the visible spectrum and infrared range, avoiding color changes during shots in various outdoor conditions. The filter features 67 mm threads on both sides, allowing stacking of additional ND filters or attaching lens caps or other filters.
