The K&F 77mm ND2 to ND400 Variable ND Filter For Video enables slow shutter speeds to be used to record movement in subjects such as waterfalls, providing a silky-smooth affect to flowing water. Reduces the amount of light entering the lens, thus decreasing camera shutter speed. Useful for situations where motion blur needs to be created (rivers, waterfalls, moving people) or large apertures must be used with flash to avoid overexposure.
- Wider outer optic to help reduce vignetting at wide angles
- Made of high quality optical glass by K&F Concept technology
- Suitable for dynamic screen, waterfalls, streams, waves, etc.
- The filters are double-threaded, so you can stack your lens cap and other accessories as needed. Great for portraiture and outdoor scenes in strong sunlight.
