The Hoya Prond Ex 500 58mm filter reduces the amount of light passing through the lens by 6 stops. When shooting videos outdoors, it allows you to adjust shutter speeds to match the frame rate while maintaining the desired depth of field. In photography, the filter enables the use of longer exposures or achieving a shallow depth of field in bright sunlight.

The ProND EX filter utilizes Hoya's ACCU-ND technology, which prevents color shifting and provides consistent image quality. It ensures equal reduction of light in both the visible and infrared spectra, preventing color changes during shooting in different outdoor conditions. It features a 58mm screw thread on both the front and rear sides, enabling the attachment of additional ND filters or lens covers with threading.
