The 80B color conversion filter transforms the color of the ambient light entering the lens by adding blue to the overall exposure. This helps match the scene to your film's white balance.
The Hoya 80B filter is helpful when:
- You are using daylight-balanced film (5500°K) and the light source is 3400°K. This commonly occurs indoors when your main light source is incandescent light bulbs.
- You are shooting with daylight-balanced film at night. The 80B filter will produce a slightly warmer look than the 80A.
HOYA Multi-Coated (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.
