The Formatt 4.5" Hi Def Clear Glass Filter is a clear (colorless) filter for color as well as black and white films. Also serves as a permanent lens protector.

Hi Def Filters

Hi Def filters do not experience color shift - Specifically designed for use with High Definition filming
Optically consistant from filter to filter
Formatt filters use the finest materials together with state of the art production techniques; This has resulted in a standard of optical perfection unmatched anywhere else
All Formatt filters are manufactured using Schott-Desag B270 Crown Optical Glass that is precision polished and ground to ensure absolute optical flatness and optimum performance

Absorbing Cell Technology

The secret to Formatt's consistency in filter design lies in its unique "Absorbing Cell Technology" (A.C.T.); This unique process allows color correct dyes to be applied to optically pure, wafer thin absorbing cells and offers a controllability that ensures the smoothest grad lines and consistent color across the whole filter surface.
This process is revolutionary compared with conventional filter dying techniques by eliminating the need to directly coat the glass surface itself; The repeatable performance gained through A.C.T. ensures that at any time you have to swap like filters for like filters mid shoot you can do so with confidence with no discernable differences in color or density.
Each filter is guaranteed flatness to a maximum 2-wave value and comes with an individual reading from a laser interferometer; Every filter is carefully verified with a densitometer and spectrophotometer to ensure consistent and accurate transmission, before leaving the factory - the result is an absolute purity of image that eliminates any unwanted colorcast caused by conventional greenish soda-lime glass.

Ultraviolet Filters

If desired they can be left on the lens at all times for protection
Haze filters provide additional benefits of correction for Ultraviolet(UV) light which can register on film and videotape as a bluish cast and can obscure distant details
Ultraviolet filters allow you to correct for the UV effect to varying degrees
