Nikon-Nikkor-200-500mm-f3.5-5.6-lens-patent

Nikon filed a patent in Japan for a 200-500mm f/3.5-5.6 and  200-500mm f/4-5.6 full frame zoom lenses:

  • Patent #2013-97322
  • Patent publication date: May 20, 2013
  • Patent filing date: November 4, 2011

200-500mm f/3.5-5.6  lens calculation:

  • Image height: 21.60mm
  • Zoom ratio: 2.40x
  • Focal length: 200.00 - 480.00mm
  • Aperture: 3.6 - 5.6
  • Angle of view: 12.21 - 5.11°
  • Lens design: 14 elements in 11 groups with one ED glass

200-500mm f/4-5.6  lens calculation:

  • Image height: 21.60mm
  • Zoom ratio: 2.40x
  • Focal length: 199.99 - 480.00mm
  • Aperture: 4.1 - 5.6
  • Angle of view 2ω = 12.26 - 5.10°
  • Lens design: 15 elements in 11 groups with one ED glass

Depending on the price, this could be a very interesting lens if it ever gets released - currently only two FX zoom lenses can reach 400mm: 200-400mm f/4G ED VR II and 80-400mm f/4.5-5.6G ED VR.
