  • Corrects tungsten film for daylight with 85B conversion

Daylight correction for tungsten film

The Tiffen 5585B is a 55mm colour conversion filter designed for photographers and cinematographers who shoot tungsten-balanced film or video outdoors. It compensates for the higher colour temperature of daylight so that recorded colours appear natural rather than excessively blue.

Consistent colour shift under sustained use

The 85B designation indicates a fixed reduction from 5500 to 3200 degrees Kelvin, matching the filter’s specified conversion value. Because the effect is optical rather than electronic, the colour shift remains stable throughout long shooting sessions and does not drift with temperature or battery state.

Standard 55mm thread for lens mounting

The filter mounts directly onto any lens or matte box with a 55mm front thread, adding minimal thickness to the optical path. Its flat glass construction resists vignetting on wide-angle lenses, while the metal ring withstands repeated attachment and removal during location changes.

Questions about this item

Does the 55mm 85B filter generate any heat or noise during long outdoor shoots?

The Tiffen 5585B is a passive glass filter with no electronics, so it produces no heat, noise or power draw regardless of how long you shoot.

What lens thread size must I already own for this 55mm filter to mount directly?

You need a lens with a 55mm front filter thread; the 5585B screws straight onto that thread without step-up or step-down rings.

Will the 85B conversion work correctly if I keep using my tungsten-balanced film stock rated for 3200 K?

Yes, the 85B lowers 5500 K daylight to approximately 3200 K, matching tungsten film rated for 3200 K and giving natural colours outdoors.
