Tokina's New Hydrophilic Coating Filter Will Keep Your Glass Dry

Tokina Water Dispersing LensSome more interesting and exciting developments out of IBC 2013 -- Tokina showcased their water dispersion filter that will keep you from cringing when you see those dark clouds coming to rain on  your parade (or set.) Tokina has done something with their filter that has not yet been done -- used a special hydrophilic coating instead of, say, a vibrating mechanism to keep water from accumulating, keeping lenses dry. Read on to get the details from a video by News Shooter.

Tokina partnered with NHK, a Japanese company that has been on the cutting edge of many developments in broadcasting, like their multi-viewpoint bullet time camera setup to produce the waterproof coating that works like similar coating on car windows and other glass, so as to not allow water to bead or gather forming droplets.

Though its intended use is by broadcasting professionals, this kind of lens would be so incredibly useful for not only that, but documentary filmmakers -- even narrative filmmakers shooting on location in a rainy area, like, I don't know, the Pacific Northwest -- a place where spotting tourists is as easy as spotting their umbrella.

Check out the video from News Shooter below and see the filter's capabilities yourself.

The proposed lenses Tokina's water dispersion filter will be available for are 77mm, 82mm, 85mm, 86mm, 95mm, 107mm, 112mm, and 127mm. According to Chris from Tokina, the first shipment will go out "early next year." No word yet on the price, but we'll keep you posted.

What do you think? Could you see yourself needing a hydrophilic coated filter in your filmmaking? Let us know in the comments.

Seriously! This IS a mistake, right?

"A hydrophile, from the Greek (hydros), meaning water, and φιλια (philia), meaning love, is a molecule or other molecular entity that is attracted to, and tends to be dissolved by, water. A hydrophilic molecule or portion of a molecule is one that has a tendency to interact with or be dissolved by water and other polar substances.[1][2] Hydrophilic substances can seem to attract water out of the air, the way salts (which are hydrophilic) do."

First bunch of sentences that come up in wikipedia on a search for Hydrophilic...

so this is a system that works because it attracts water (as denoted by philic) as opposed to "hydrophobic" where the material repells water... uhm... interesting approach to say the least...

Expected it to behave more like this:

back in 2006 I went to Next Fest in NYC. GE had been studying dragon fly wings, specifically their amazing ability to shed water. They had a glass dish petri dish that was impregnated with the same microscopic pattern that existed on the dragon fly wings. When water was dropped into the dish it wouldn't pool and flatten out like the regular glass dish but instead the water would stay in a perfectly round orb. Never making a molecular bond to the glass. You could literally see the fulcrum of the water droplet. It was a friction less or as close as I have ever seen. Now I have looked for news of it and have never found anything. But to me the applications seemed endless, lens tech being one of them

Hydrophobic. Of course hydrophobic :D

These will be great for those in the Adult film industry.

I've been shocked that GoProHero3 Black editions haven't caught on in that industry. I mean... Rugged waterproof tiny camera, can strap on actors head. Shoot 2.7k 24fps or even 120 fps slowmo finales....
Not that I would have any clue of what they are doing of course... erhm.... cough cough...

Do I need this. Heck yes. I have saved this page and still wait to hear where I can buy this. I need bulk of these for a longterm timelapse camera box. A few of them.
Can we buy this yet and if so where ????

Or you could use Rain-X like we've always used
