The Hoya Prond Ex 1000 49mm filter reduces the amount of light passing through the lens by 10 stops. This allows for adjusting shutter speeds while shooting video outdoors, maintaining the desired depth of field. It also enables you to achieve motion blur on moving subjects, giving them a more cinematic appearance.

In photography, the filter allows for longer exposures or creating a shallow depth of field in bright sunlight.

The ProND EX 1000 filter utilizes Hoya's ACCU-ND technology to prevent color shift, ensuring consistent image quality. The ACCU-ND guarantees equal light reduction in the visible and infrared spectrum, reducing color change when shooting under different outdoor conditions.

Additional ND filters can be stacked on the front or a threaded lens cover or another filter can be attached.
