Darkens entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required, suitable to record movement/image blur in subjects such as waterfalls, streams, waves, clouds or any fast moving subject

Eliminates buying many fixed ND Filters as it is designed with a built-in rotating ring that controls neutral density ranging from ND2 to ND2000 (1 to 11 f-stop). The heavier the density, the slower your shutter speed will be

When using this variable ND filter at high ND values (9 f-stop or above) on wide angle lenses, it would appear "X" cross mark, vignetting, reflections or blur in the picture, this is unavoidable according to the structure and operating principle of a variable ND filter. If this is not acceptable to you, please go for a non variable ND filter, for example, a popular fixed ND1000 10 f-stop ND filter

The filter is constructed from German famous brand optical glass that features 9 layers of anti-reflection coatings on each side(total 18 layers), making the filter anti-scratch, anti-static, oil and water-resistant

Compatible with any lens with 46mm diameter filter thread - This variable ND filter is double threaded, has 46mm inner thread(male) and 49mm outer thread(female), this design allows you to put on any 49mm thread accessories such as lens cap, screw-in type lens hood to the front of the filter
