Hoya Variable ND3-400 filter 72mm

The Hoya Variable Density filter reduces the amount of light entering the cell between 1.5 and 9 apertures. The Variable filter is handy because you can adjust how much the filter reduces the amount of light depending on the situation. So, for example, on a bright summer's day when you need a long exposure time, the ND filter is an indispensable tool.

The filter's operating principle is the angle adjustment of two Linear polarization angles. In this case, image quality is not affected. The body is made of thin aluminium, so it is sure to withstand use.

Key features:

• Filters light between 1.5 and 9 aperture values
• Self-adjustable filtration efficiency
• Useful in bright daylight
• Multi-film coated
• Thin aluminium body
• Allows the use of wide apertures or long exposure times
