One of the features of yesterday's Nikon high-end lens announcements that didn't get all that much attention was that Nikon has introduced a new coating for some of the elements, which looks like it might go a long way in repelling dirt and grime. In this dramatic video, Nikon shows what this fluorine coating can do, and how its powerful beading technology means that even the likes of permanent marker, motor oil, and oil based paints can be wiped right off.

On Nikon's lens glossary, the company describes the new coating as:

fluorine coat

Nikon's fluorine coat effectively repels dust, water droplets, grease or dirt, ensuring easy removal even when they adhere to the lens surface. Thanks to Nikon's original technology, it delivers higher durability and is more peel-resistant. Compared to other manufacturers' coating of a similar kind, fluorine coat endures a higher frequency of lens surface wiping and provides longer-duration staying power. Its anti-reflective effect also contributes to the capture of clear images. Nikon's fluorine coat is being applied first to the AF-S NIKKOR 400mm f/2.8E FL ED VR and AF-S TELECONVERTER TC-14E III.

Keep in mind, this isn't to be confused with a fluorite lens, which Nikon has used for since at least 2013, and is marked by "FL" in the lens's name. The new 400mm f/2.8E FL ED VR has that too, but, for example, the 800mm f/5.6 FL ED VR doesn't have the new coat.
