Introduction:
FOTGA Neutral Density (ND) filters can reduce the intensity of light without appreciably changing its color. It allows to slower shutter speed under strong sunlight exposure in order to achieve motion blur (waterfalls, ocean, clouds…). It also allows wider apertures for effectively decreasing depth of field.
With FOTGA Variable neutral density filters, you can select the intensity from ND2 (1 f-stop) to ND400 (8+ f-stops) by rotating the front ring. You don’t need to carry a bunch of filters for shooting, carry ONLY a single filter with the same capability with ND2, ND4, ND8, ND16, ND32…and ND400. It is highly recommended by famous photographers and film directors.
FOTGA variable ND-MC filter is designed based on the previous version and adopts the following advanced features.
