Hoya A-7285B-GB Overview

The Hoya 72mm 85B Color Conversion Hoya Multi-Coated (HMC) Glass filter will produce natural colors when shooting with tungsten film outdoors.

What do you do when you must take some photos outdoors and all you have left is tungsten film? Using tungsten film in daylight will produce a bluish cast in the photograph. The 85 series of filters will "bring back", i.e. color balance the tones in your images. These yellow filters are used to correct differences in color temperature between the recording medium (film/video) and the light source.

An 85B filter converts tungsten film to daylight. An 85C produces the coolest results - more than either the 85 or 85B. However, it is interesting to remember that an 85C is also useful as a creative warming filter with daylight film in daylight.

Multicoated to minimize reflection at the filter surfaces which reduces flare and ghosting.

Note:
Whereas the 85 series is used for tungsten film under daylight conditions, use the 80 series of filters when using daylight film under tungsten lighting
As one of the premier filter manufacturers, Hoya filters continue to made from quality glass assuring the photographer clear, sharp and accurate images
Hoya filters consistently provide even color all the way through the filter; All surfaces are ground and polished to specific thickness and tolerances
Even non-multi-coated Hoya filters have one layer of anti-reflective coating applied to each surface of the glass; Hoya's single layer coating decreases light reflection off the surface from approx. 9% to an average of 4-5%
