Hoya 82mm W12 Umber Warming Color Conversion Multi-Coated Glass Filter

W12 color conversion filter warms the ambient light entering the lens by 2200 Degree kelvin (+120 mired shift) by adding dark amber color to the overall exposure. This filter is excellent when using tungsten balanced film like Cinestill 800T and want to create a natural look when shoot outside during the daytime.

The Hoya W12 filter is helpful when:
• You are using tungsten-balanced film and want to capture natural colors during the daytime instead of the heavy blue cast the film will create.
• You are shooting tungsten-balanced film indoors with 5500 Degree K light sources like flashed or studio strobes
• W12 is stronger than W10 so it will produce a more neutral look when used with standard tungsten balanced films

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.
