Hoya 52mm Variable Density II Filter

Hoya Variable Density II Filter 52 mm is a density adjustable filter with a rotatable frame and a knob. This essential photography tool can replace ND Neutral Density filters as it provides an adjustable range of density that lowers the shutter speed in still shooting. It prevents the image from overexposure to light in overly lit conditions and minimises the risk of the vignette effect.
