Nikon Patent for AF-S Nikkor 600mm f/4E FL Lens

Egami spotted a new patent filed by Nikon. The new patent describes the Nikon AF-S NIKKOR 600mm f/4E FL ED VR telephoto prime lens.

Previously the company is rumored to add a fluorine coating to all of its high-end telephoto lenses. The list of upgrade candidates includes five models getting replaced within two years. The list includes the 200mm, 300mm, 500mm, 600mm, and 200-400mm.

First signs of the fluorine coating replacement has been surfaced in the lens patent. This lens will replace current AF-S NIKKOR 600mm f/4G ED VR lens, with new Fluorine Coating feature.

Next Nikon Lens with Fluorine Coating Will Be The  AF-S Nikkor 600mm f/4E FL ED VR

Nikon’s fluorine coating currently presented in the 800mm f/5.6 and the newly announced 400mm f/2.8E FL ED VR telephoto lenses. Now there are five new models that are being replaced. First lens from the list being replaced by the new coating could be the 600mm f/4G ED VR.

• Nikkor 200mm f/2G ED VR II (back-ordered at Amazon, Adorama)
• Nikkor 300mm f/2.8G ED VR II (back-ordered at Amazon, Adorama)
• Nikkor 500mm f/4G ED VR (back-ordered at Amazon, Adorama)
• Nikkor 600mm f/4G ED VR (back-ordered at Adorama)
• Nikkor 200-400mm f/4G ED VR II (in stock)

All lenses with a fluorine coating will employ the “FL” designation and this coating makes the lenses more resistant to dirt, dust, grease, and water droplets.
