52mm Variable ND 0.3-1.8 Filter
Variable 1 to 6 Stop Neutral Density Filter
This 52mm Variable ND 0.3-1.8 Filter from Heliopan is a variable 1 to 6 stop neutral density filter designed to reduce all different wavelengths of light for an even reduction in light. This allows your shutter speed to be slowed, which is particularly useful when photographing water and tides, or when a dramatic effect is desired. Simply rotate the front ring to select the desired degree of ND.
The filter uses Schott glass, to ensure your images are sharp and clear, with true colour and contrast. The black brass mounting does not feature front threads for mounting additional filters or lens caps.
