81A Color Correction

    PRODUCT DISCONTINUED - for Reference Only
  • Warms color temperature 200°K to balance cool lighting conditions 
  • Designed for film photographers
  • Helpful on overcast days and shady conditions
  • 6 layers of HMC multi-coating


  • The 81A color correction filter warms the ambient light entering the lens by 200° Kelvin by adding "orange" to the overall exposure. The filter helps fine-tune the color or look of your scene to match your film's white balance.

    The Hoya 81A filter is helpful when:

    • You are using daylight-balanced film and the light source is cooler than the traditional 5500° K and you need a specific amount of color correction to match your film type.

    • You want to add a slightly warmer look to your portraits.

    • You are shooting in overcast or shady conditions.

    HOYA Multi-Coat (HMC) filters are recommended for enhancing the performance of today’s multicoated lenses. These popular filters minimize reflection, reduce flare and ghosting, and result in over 97% average light transmission.
