Heliopan
46mm Slim Variable ND 0.3-1.8 Filter
Variable 1 to 6 Stop Neutral Density Filter
This 46mm Slim 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. Simply rotate the front ring to select the desired degree of ND. This allows your shutter speed to be slowed, which is particularly useful when photographing water and tides, or when a dramatic effect is desired. Your image colour will not be affected.The filter uses Schott glass, to ensure your images are sharp and clear, with true colour and contrast. The black brass mounting ring is built with a slim mount design that helps to prevent vignetting when used on wide-angle lenses. To further reduce the chance of vignetting when used with wide angle lenses it does not feature front threads for mounting additional filters or lens caps.
