Tokina 77mm Hydrophilic Coating Protector Filter
Key Features
  • Clear Protective Filter
  • Hydrophilic Coating Stops Water Beading
  • Provides Clear View under Rain
  • Photocatalyst Layer Restores Filter
The Tokina 77mm Hydrophilic Coating Protector Filter is a clear filter designed to completely prevent water from beading on its front surface when photographing or recording under rain or other wet conditions. Its top hydrophilic coating evenly repels moisture, but creates no additional coloration or contrast, and adjustments to exposure are not required while using this filter. A photocatalyst layer between the hydrophilic coating and the underlying glass provides the ability to restore the hydrophilic coating's effect after it comes into significant contact with moisture. This is accomplished by exposing the front of the filter to ultraviolet light for four hours or sunlight for eight hours under dry conditions. Aside from moisture, scratches and other elements are prevented from reaching or damaging a lens while the Tokina 77mm Hydrophilic Coating Protector Filter is in use.

Can be used also just as a lens protector from the elements? And is it threaded (if I understood correctly) so a variable ND can be screwed in front of it? Thanks
Asked by: David
Yes, the Tokina 86mm Hydrophilic Coating Protector works well as a lens protector. It is threaded in the front of the filter and will accept 86mm variable ND filters.

question

Why is this so expensive?
Asked by: Myles P.
That would be due to the manufacturing process. The hydrophilic coating is very expensive to produce.
