Nikon New Fluorine Super Coating Demonstrated

Earlier this week Nikon introduced a new version of its long telephoto lens – AF-S Nikkor 400mm f/2.8E FL ED VR where the marking FL relates to a new type of coating based on Fluorine.

The video above – published by Nikon Japan earlier this week shows a demonstration of the new Fluorine coating in action facing water and other liquids. Part of the glass shown on the video was treated with the coating and part of the lens was not treated and it is very easy to see the differences.

The glass from the video – on the right with no coating and with coating on the left


hydrophobic and superhydrophobic coatings which are made to repel liquids for surfaces have been developed by many companies in recent years. The Nikon Fluorine coating needs nots only to be able to repel liquids, but also to keep the very high optical qualities of the very expensive lenses which are using it. So far Nikon only used this coating on its top of the line new 800mm lens announced last year and the new 400mm lens (both cost well over $10k).

The new AF-S Nikkor 400mm f/2.8E FL ED VR announced this week – has Fluorine coating 




What we would like to see next from Nikon (and maybe other manufacturers) are filters which can be used on any lens which use Fluorine coating or some other type of superhydrophobic coating so we can have the benefits that you see in this video without paying thousands of dollars on professional glass.
