Urth 77mm ND2-400 (1-8.6 Stop) Variable ND Lens Filter

The Variable ND2 400 filter offers 1 to 8.66 f stops of light reduction, giving you more creative control in variable light.

By blocking 1 to 8.66 f stops, variable light allows you to use larger apertures for smaller depth of field effects and slower shutter speeds for long exposure effects without overexposing your images.
Cinematographers can use our ND2 400 Variable ND filter for more cinematic effects in low and bright light.
For wide angle lenses (less than 35mm of focal length) and telephoto lenses (70mm+ of focal length), we recommend our Variable ND2 32, ND8 128, ND64 1000 or fixed ND filters.
