Essential Tool for Film Photographers

The HOYA 49mm W10 Umber Warming Color Conversion Filter is designed for photographers shooting tungsten-balanced film in daylight conditions. It adds a rich, dark amber hue to the overall exposure for a natural, warm look. This filter is excellent for use with CineStill 800T film stock.

1950 Degree Kelvin Color Temperature Shift

This filter converts color temperature by 1950 Degree K with a +100 mired shift. It is equivalent to an 85 filter and is slightly less intense than the W12 variant for a subtler warming effect. The conversion allows tungsten film to render correctly under 5500 Degree K light sources like flash or strobes.

Simple Thread Mount with Multi-Coated Glass

The filter screws directly onto any lens with a 49mm filter thread for quick installation. Six layers of HMC multi-coating minimize reflection and reduce flare and ghosting while achieving over 97% average light transmission. Ensure the thread size matches your lens diameter before mounting.
