Hoya 49mm Pro ND EX 64 Filter

The 49mm ProND EX 64 Filter from Hoya reduces the amount of light passing through the lens by 6 stops. When shooting video outdoors, you can set shutter speeds to match your frame rate while maintaining the depth-of-field you want. When shooting moving objects, you can achieve a motion blur that makes the image look more cinematic. For photography applications, the filter lets you use longer exposures or achieve a shallow depth-of-field in bright sunlight.

The ProND EX 64 filter uses Hoya's ACCU-ND technology to prevent color shift in order to deliver consistent image quality. ACCU-ND ensures an equal reduction of light in both visible and IR spectrums so that you don't experience color shift when shooting in different outdoor conditions. The filter features 49mm threading on both the front and rear sides. Additional ND filters can be stacked on the front, or you can attach a threaded lens cap or other filter.
