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!
