The 3-stop, 49mm ProND EX ND Filter from Hoya reduces the amount of light passing through the lens. 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 ND 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.

Q: 1. I have a 32-64mm Fuji GFX zoom lens on a GFX 50R. Can this filter be used at full wide angle without vignetting with this lens? Thanks.

A: The B+W 77mm XS-Pro Digital ND Vario MRC-Nano Filter will not vignette the Fuji 32-64mm lens. This is because the front of the filter is 82mm. By having a larger front than the mount, it reduces the risk of vignetting on wide angle lenses.
