  • Converts 4900°K light sources to match 3200°K Tungsten balanced film
  • Designed for film photographers
  • Produces accurate colors on Tungsten film when shooting in daylight
  • 6 layers of HMC multi-coating

The 85C color conversion filter transforms the color of the ambient light entering the lens by adding orange to the overall exposure. This helps match the scene to your film's white balance.

The Hoya 85C filter is helpful when:
  • You are using tungsten-balanced film (3200°K) and shooting in daylight. It will produce a warmer look than the 85 and 85B filters since it is the weakest filter in the series.

  • You are shooting with tungsten-balanced film (3200°K) indoors with 5500°K light sources, such as flashes, window light and studio strobes.
