The JJC F-NDV49 Variable ND Filter is a grey scale filter with a variable neutral density from ND2 to ND400. By turning the filter you can vary the amount of light that passes from 1 stop to 9 stops without affecting the original colours. This gives you very precise control over exposure. This gray filter is therefore very suitable for taking dynamic photos of waterfalls, streams, waves, etc.
High-quality optical glass from Japan
The F-NDV filter uses high quality optical glass from Japan which is coated on both sides with 16 layers for high light transmission. The aluminium frame is only 7mm high, reducing the risk of vignetting when using a wide-angle lens. A handy waterproof storage box is included to store the filter.
