52mm W10 Umber Warming Filter

The HOYA 52mm W10 Umber Warming Color Conversion Multi-Coated Glass Filter shifts color temperature by 1950 degrees Kelvin (+100 mired shift). It is designed for film photographers using tungsten-balanced film in daylight conditions. The filter features 6 layers of HMC multi-coating on glass.

Suited for Tungsten Film Users

Photographers shooting CineStill 800T or similar tungsten films outdoors will benefit from the subtle dark amber hue that reduces blue cast. It also corrects 5500K flash or studio strobe light for tungsten film. Those needing a stronger correction should consider the W12 variant.

+100 Mired Shift Conversion

The decisive specification is the +100 mired shift, equivalent to an 85 filter, which converts daylight to tungsten balance. This specific shift determines if the filter matches your film stock and lighting scenario.

Questions about this item

Will the 52 mm thread on this W10 filter fit the 52 mm front of my existing lens?

Yes — the filter is built with a 52 mm mounting thread, so it screws directly onto any lens or adapter that shares that 52 mm diameter.

How can I verify the filter is delivering the correct +100 mired shift after I mount it?

Shoot a test roll of tungsten-balanced film such as CineStill 800T in daylight; the processed images should show neutral, warm tones instead of a heavy blue cast, confirming the 1950 K conversion is working.

Does the package include a protective case or do I need to buy one separately?

The filter ships in its original protective pouch; a hard case or additional pouches are not included and must be purchased separately if desired.
