Urth 67mm ND2-400 Variable ND Lens Filter - 1-8. 6 Stop Range, Ultra-Slim 20-Layer Nano-Coated Neutral Density Filter for Cameras.

By blocking 1 to 8. 66 fstops, you can use wider apertures in variable light for shallower 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 to create more cinematic effects in low and bright light. For wideangle lenses, we recommend our Variable ND232, ND8128, ND641000 or fixed ND filters.
