Nikon's New Fluorine Coating Is Your Best Protection Against a Dirty Front Element

Nikon provided a new video highlighting the benefits of using its fluorine coating, first used on the just-announced updated 400mm f/2.8 lens. In addition to adding a certain clarity to the image because of its antireflective properties, the new 400mm f/2.8 benefits from the fluorine coating's ability to repel just about anything that might hit it. I want this on all of my lenses!

Can't wait to buy the spray on kit.

I'll 2nd that. I'd probably spray my phone & tablet with the stuff too.

So essentially this is Rain-X for your lenses.

...wait, wonder if i just put my current rain-x on an old unused lens?? hmmm! Testing time!

Just wondering how it compares with the previous generation coating. This is tested against not treated glass. But even said that, I like it!

To the best of my knowledge, previous coatings had little to no effect on the attraction to dirt/moisture, etc. This is the first to do so, I believe...and it's apparently VERY good.

I agree that its very good. If it was a spray can I could buy, I'd be running to te store to "update" all my lenses.

I apologize for sounding like a fanboy, but Canon has used flourine on the sensors for many years and on their lenses for at least 3 or 4 years. They've also been using fluorite elements for a very long time which Nikon's glossary ( (still) says is, "However, fluorite easily cracks and is sensitive to temperature changes
that can adversely affect focusing by altering the lens' refractive
index", even though Nikon is now using them in the 800mm and then new 400mm. I realize Canon does the same thing with Nikon - they both use the same arguments against each other over the years, but wanted to point this out...

In this case, it's good news for Nikon shooters as the stuff works really well :-)

I wonder if politicians will start using this...
