Hoya HMC NDx2 Filter | 55mm

In conditions of extreme light intensity, such as sunshine on snowy mountains or on the beach, or when using a camcorder, ND (Neutral Density) filters are recommended as essential.

Neutral Density filters are often ignored by photographers, but they have several uses and offer the possibility to achieve otherwise unachievable results. ND filters appear grey and reduce the amount of light reaching the film, they have no effect on colour balance.

Four main uses:

  • To enable slow shutter speeds to be used, especially with fast films, to record movement in subjects such as waterfalls, clouds, cars, seas etc.
  • To decrease depth of field by allowing wider apertures to be used, which helps separate subjects from their background.
  • To decrease the effective ISO of high speed film (ie: above ISO400) and allow it to be used outdoors in blight situations.
  • To allow cine and video cameras (which have fixed shutter speeds) to film subjects such as snow, sand or other bright scenes which would normally cause over-exposure.
Neutral Density Factors
  • 2x = ND.3 (exposure adjustment = 1 stop, reduces ISO 1/2)
  • 4x = ND.6 (exposure adjustment = 2 stops, reduces ISO 1/4)
  • 8x = ND.9 (exposure adjustment = 3 stops, reduces ISO 1/8)

Hoya filters ensure photographers clear, sharp and accurate images by continuing to make their filters from quality glass. Filters are produced to provide even colour, polished thickness and tolerance and all surfaces are ground.

This filter has been produced to fit all lenses with a 55mm thread size. Check the end of your lens to verify the required size.
