Tokina Hydrophilic Coating Filter Square 4x5.65

The new Tokina hydrophilic coating filter is particularly useful for professional filmmakers who shoot videos in rain or very humid conditions. It is also beneficial for sports photographers, landscape photographers, and nature photographers who need to take pictures in rainy weather without constantly wiping water droplets and dirt from the lens. When rainwater hits the new Tokina hydrophilic coating filter, it spreads into an even, invisible film over the lens. This allows for a clear image to be captured at any time, even in the rain, ensuring high-quality footage.

Tokina hydrophilic coating filters are available in round sizes: 77, 82, 86, 95, 105, 112, and 127 mm. Filter plates are available in sizes: 4x4 inches and 4x5.65 inches. The filter works by charging with sunlight or other UV light. The underlying effect is photocatalysis, where excitons (bound electron-hole pairs) are formed through light charging, breaking down water and dirt into their molecules. This charging prevents the formation of droplets and also the organic degradation of dirt on the glass surface, allowing it to dry quickly and remain clean.

Thanks 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 common screw sizes, the Tokina hydrophilic coating filters are also available in two sizes as filter plates. The special surface treatment makes this filter four times harder than normal optical glass, making it exceptionally robust. This allows filmmakers an almost unobstructed view of the subject and crystal-clear shots even in the rain.
