HELIOPAN Neutral Density Filter

Filter Thread Size
  • Why a HELIOPAN Neutral Density Filter?

    A Heliopan gray filter (neutral density filter) reduces the amount of light that is absorbed by the lens. The color character is not affected. Heliopan gray filters are made of Schott glass and can be obtained in the following densities:

    density permeability elongation factor f-stop
    ND 0.3 50.00% 2x -1
    ND 0.6 25.00% 4x -2
    ND 0.9 12.50% 8x -3
    ND 1,2 6.25% 16x -4
    ND 1.5 3.12% 32x -5
    ND 1.8 1.56% 64x -6
    ND 2.0 1.00% 100x -6.66
    ND 3.0 0.10% 1000x -10

     Unfortunately, the so-called neutral-gray filters (ND) are referred to the rules of densitometry with logarithmic densities, but the photo user is interested in how many time steps (or f-stops) light the filter swallows. With the help of the above table, this can be easily determined.

  • Uses, Tips & Examples

    Each camera has 2 light paths: the path through the lens and the unwanted through the viewfinder. With a dense gray filter in front of the optics, the additional light from the viewfinder can be the reason for image interference, a viewfinder shutter or black tape create a remedy.


    The very dense gray filter ND3,0 produces a warm tone for physical reasons. Here Heliopan UV / IR cut filter helps before the gray filter. At very long exposure times, the inherent self-exposure of the sensor produces noise, especially in the blacks of the image. Activate the function: Noise reduction, this will help.


    When shooting in the evening and at night close the shutter completely, place a strong neutral density filter and use the tripod. Long-term shots allow people to blur and deliver particularly surreal effects.


    Water in a torrent should be rendered " frothy ". 1/250 sec and aperture 8 are the normal values: With an ND 2.0 filter the exposure time has to be extended by 6 2/3 steps. 7 levels are the range of 1/250 to 1/125, 1/60, 1/30, 1/15, 1/8, 1/4, 1/2 sec. The correct gray filter is therefore the ND2,0. Gray filters between ND 0.9 and ND 3.0 are sufficiently dense for all photo-technical applications except the sun photography, a complete equipment would be eg the 3 filters with N0,9, ND 2,0 and ND 3,0. Please refer to the image of the torrent over rocks. 

  • Product Overview

    The Heliopan ND Filter creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily. Neutral density filters do not affect the coloration of the image and are ideal for pairing with other filters.

    To prevent internal ghosting and reflections, each glass surface includes four layers of anti-reflection coating. Together, these eight coatings offer greater protection to the filter substrate and help it to stay clean for longer than with uncoated filters.

    This Heliopan neutral density filter is constructed from SCHOTT glass for increased optical clarity as well as color fidelity and features a brass filter ring for enhanced durability and jamming prevention.
