New Nikon 58mm f/1.2 full frame lens patent


Nikon filed two more patents (2013-019992, 2013-011831) in Japan for a new full frame 58mm f/1.2 lens. In the past there have been similar patents for a 50mm f/1.258mm f/1.4 and 58mm f/1.2 lenses. Here are the technical details:

  • Focal length: 58.0216
  • Aperture: 1.229
  • Half angle of view: 20.82 “
  • Image height: 21.6
  • Lens length: 122.05004
  • Backfocus: 38.01861
  • Lens design: 9 elements in 7 groups with three aspherical surfaces and possibly two ED elements (2 & 4)

Maybe Nikon is really serious about recreating the legendary Ai Noct Nikkor 58mm f/1.2 lens (read more about it here).
