Get ready to spend a ton of money to spy on your neighbors! At least, that’s what you may want to do with Nikon’s 600mm f4 FL ED VR that was patented recently. Nikon Rumors is reporting that a new patent was just put in by Nikon Japan and recently published for the lens. The coating is designed to help break up liquids that touch the surface of the elements.

Currently on the marker is a Nikon 600mm f4 Lens that costs just shy of $10,000 and even that is a special use lens probably only used by sports and wildlife photographers. Even so, it’s rare that any one photographer owns the lens as many of them are in the hands of agencies and news wires. According to Ken Rockwell though, their latest lens was announced in 2007–so it will probably be a while until we see it.
