The Ultimate solution to protect from liquid accumulation

Hydrophilic Coating

  • When water hits the filter, it spreads into a film over the glass instead of forming droplets. This helps to maintain a clear view under a variety of weather conditions and for taking photos or video around water.

  • Through a special treatment of the hydrophilic surface, this filter is also extraordinarily durable.

  • This self-cleaning filter helps to keep dust and debris away with exposure to the sun or UV light, prolonging the life and performance of the filter.

Hardened Glass

  • Ultra Clear High Transparency Optical Glass.

  • Chemically Enhanced Optical Glass is 4x Stronger than the Normal Optical Glass.

Ultra Thin Frame

  • Wide-Angle Lens Compatible Ultra Thin Frame.

1. Feature

When water droplets form on the camera lens from rain or wet conditions, visibility is obscured. Use of the Tokina Hydrophilic
Coating Filter under these conditions gives a virtually uninterrupted clear view of your subject.

As shown in the diagram below, a photocatalytic layer is combined with a hydrophilic layer so when water comes in contact with
the lens, it is immediately spread into a thin layer, providing a much clearer view in rainy weather than with any other conventional
filter. The photocatalytic layer also makes the filter self-cleaning when exposed to light, prolonging the performance of the
hydrophilic effect.


Hydrophilic LayerHydrophilicity is the phenomenon by which water droplets are transformed into a film. Looking at the surface of the hydrophilic layer, the uneven micro droplets are dispersed into a thin film. As more and more dirt adheres to the filter, the effect of the hydrophilicity will diminish.Photocatalytic LayerWith sunlight or ultraviolet light, electrons or hole pairs are generated and a photocatalytic reaction occurs which breaks down dirt. In this way, the hydrophilicity of the filter is also protected.

2. Precautions

2-1 Prior to First Use
The filter may not exhibit the hydrophilic properties on first use. If this is this case, please expose the filter to ultraviolet light as
described in Section 3.

2-2. Care
After use, gently wipe the coated surface with purified water and then wipe clean with a cotton cloth. Please be careful in using
this procedure for cleaning once the hydrophilic filter is worn or has diminished in performance.

1) Wear latex gloves
2) Immerse cotton cloth into cleaner and apply evenly to the coated surface
3) Cover with a piece of plastic so as not to let the filter dry out. Let stand for 30 minutes or more.
4) Next, remove the cleaning solution by rinsing the lens with purified water.
5) Wipe dry with a clean, cotton cloth and expose to the sun to irradiate with UV rays.
Using excessive force to wipe or cleaners other than what is recommended could diminish the effectiveness of the hydrophilic 
coating so use care.

2-3. Caution
- Don't ever use a fluorine or silicon based cleaner as these substances can irreparably damage the hydrophilic coating.
- The hydrophilic effect can deteriorate if left for prolonged periods in the dark, so please store in a location which is occasionally exposed to the sun.
- The filter should never be submersed in water as it is not completely waterproof.

3. Ultraviolet irradiation
Please irradiate for 3 hours or more with ultraviolet 1mW/cm2 or more in a dust-free environment.
