Hoya 72mm Variable Density Filter

The Hoya 72mm Variable Density Filter supplies complete control of just how much light that hits the lens. It's simple to slow down the shutter speed in extensive sunlight to produce incredible creative results like decreasing the movement of any moving objects, for instance, motion blur with cars and trucks, rough seas and people.

The filter has a revolving ring which features scaling to help you modify the degree of filtering, from minimum to maximum, it supplies a 1.5 - 9 stop exposure reduction.

This type of Hoya filter works by using two polarizing values that blocks the amount of light that travels into the filter and then into the camera lens. If set up at the minimum just a 1/3 of the light passes into the image.
