Nikon has provided a new video highlighting the benefits of using its fluorine coat. The first lens to use this new coating is the just-announced updated 400mm f/2.8 lens. The fluorine coat has the ability to repel just about anything that would come in contact with it like water, mud, permanent marker and even paint!
Here is Nikon's explanation of it:
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.Here is a video of it in action:
