Tiffen 77mm 85 Conversion Filter

The Tiffen 77mm 85 filter is a glass camera accessory built for photographers who shoot tungsten-balanced film in daylight conditions. It corrects the bluish cast that occurs when tungsten film is used outdoors, delivering natural colour rendition without the need for digital correction later. The 77mm thread fits a wide range of lenses, making it a versatile addition to a film-based workflow.

Colour conversion capacity and limits

The 85 series filter converts daylight to match tungsten film, removing the dominant blue shift and producing slightly cooler results than the 85B variant. It is designed specifically for tungsten film in daylight; it does not correct fluorescent or mixed lighting, and it will not warm daylight film in the same way an 85C would. When the light source changes or the film stock differs, the filter no longer provides accurate conversion.

Optical glass construction and lens protection

The filter is crafted from high-quality optical glass that maintains clarity and minimises distortion across the frame. Its robust frame shields the front element of the lens from scratches and accidental impacts during outdoor shoots. No additional coatings, pouches or software are mentioned in the specifications, so the accessory relies solely on its glass quality and mechanical durability.
