Nikon patents update (part 2)

Back in November Nikon filed patents for 24mm f/2.8 and f/3.5 full frame lenses. Few weeks ago, a new patent 201159288 was filed in Japan for a 24mm APS-C lens:

Two different versions of this lens were described in the patent – one with f/2.0:

  • Focal length: 24.600mm
  • Back focus: 25.182mm
  • Aperture: 2.08
  • Image height: 14.2mm
  • Angle of view: 61.09 °

and another one with f/2.8:

  • Focal length: 24.600mm
  • Back focus: 25.917mm
  • Aperture: 2.89
  • Image height: 14.2mm
  • Angle of view: 61.08 °

It seems also that Nikon is serious about adding a protective mount cover on their mirrorless camera. They filed another patent in Japan (201113399) for a mechanical mount cover that will prevent dust from getting inside the camera:

The mount cover is mechanical and it does not need battery in order to operate.
