The Tokina Hydrophilic Coating Filter is of particular benefit to professional filmmakers who shoot videos in rainy or very humid conditions. But also sports photographers, landscape photographers and nature photographers who have to shoot in rainy weather and do not want to constantly wipe water droplets and dirt off the lens. When rainwater hits the new Tokina Hydrophilic Coating Filter, it spreads out to form an even, invisible film over the glass.
This works by charging the filter with sunlight or other UV light. The underlying effect is caused by so-called photocatalysis, in which excitons (bound electron-hole pairs) are formed by the light charge, which break down water and dirt into their molecules. The charging of the filter thus prevents the formation of droplets on the one hand, and on the other hand also causes the organic decomposition of dirt on the glass surface, which dries quickly and remains clean.
Due to the extra-thin frame, it can also be used without restrictions on wide-angle lenses. In addition to the classic round filters in all standard sizes for screwing on, the Tokina Hydrophilic Coating filters are also available in two sizes as filter discs. Thanks to the special treatment of the surface, this filter is also four times harder than normal optical glass and therefore extremely robust.
This allows the filmmaker to have an almost undiluted view of the subject and crystal-clear shots even in the rain.
Diese besonderen Spezialfilter von Tokina übernehmen die Aufgabe der klaren Durchsicht. Bei Filmemachern wird diese Art oberflächenvergüteter Filter bald immer beliebter sein, da sie bei starkem Regen die Tröpfchenbildung auf dem Filterglas, durch ihre hydrophile Beschichtung (photokatalytisch selbstreinigende Oberfläche) verhindern. Die Beschichtung wird durch UV-Strahlen aktiviert und sorgt für eine zuverlässige Selbstreinigung. Im Gegensatz zu anderen Objektiv- oder Filterbeschichtungen entfällt hier das manuelle Putzen mittels Putztuch.
Klarer Blick - für klare Filme.
