Optical Effect

  • 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.
  • Hoya Multi-Coated (HMC) filters are renowned for their ability to minimise reflection at the filter surfaces which reduces flare and ghosting. The result is an average light transmission of over 97%, giving sharp contrast and well balanced color.
