The patent for the upcoming Nikon AF-S 28mm f/1.8G full frame lens is now online

Patent application 20120069440 is for the upcoming Nikkor AF-S 28mm f/1.8G full frame lens. I have no exact announcement date yet, but I believe this lens will be introduced in 2012. The patent contains several different calculations and one of them is for 28mm f/1.8:

  • f = 28.08 (focal length)
  • FNO = 1.84 (aperture)
  • 2ω = 76.4° (filed of view)
  • Y = 21.6 (image height)
  • TL = 124.5 (total lens length)

The next patent application 20120069441 is for a 16-35mm f/2.8 lens:

  • f = 16.48 – 24.00 – 33.95 (focal length)
  • FNO = 2.884 – 2.884 – 2.884 (aperture)
  • 2ω = 108° – 84° – 63° (filed of view)
  • Y = 21.64 – 21.64 – 21.64 (image height)
