FILTER	From (light source)	To (neutral)

85	5300°K	3200°K
85C	4900°K	3200°K

Hoya color conversion filters are manufactured in Japan using hand-selected silicates that are carefully smelted and blended to yield high-performance optical glass. Hoya then applies 6-layers of a Super Multi-Coating (SMC) formula which greatly reduces or eliminates reflections on the surface of the glass. This means the filter has virtually no unwanted effect on color, contrast, or clarity of the final image.

The filter features a lightweight standard aluminum frame to house the glass (Ø46mm - Ø82mm sizes) and signature Hoya casing.
