Neutral gray filter FreePower ND2-400 Variable with a thread diameter of 77 mm. It was designed for enthusiasts of landscape and city photography, looking for a universal solution for dynamic lighting conditions. The filter allows you to freely reduce the transmitted light in the range from -1 to -9 EV (approximate values).
The design of the ND2-400 Variable filter consists of two polarizing filters. They are positioned relative to each other by means of a rotating ring. The operating range of the filter is determined by the scale and the MIN and MAX values printed on the filter ring.
The most popular use of the filter is landscape photography - its properties allow you to achieve the effect of blurring the movement of water or clouds or reduce excessive lighting of the scenery (especially in summer with a cloudless sky).
