Nikon has released firmware version 1.01 for its D5300 and D5500 cameras. Both updates add support for the AF-P DX NIKKOR 18–55mm F3.5–5.6G VR and AF-P DX NIKKOR 18–55mm F3.5–5.6G lenses, Nikon's first DX lenses to offer stepping motors, as well as an a5 Manual focus ring in AF mode option for the D5500. Both updates also bring several bug fixes correcting issues affecting each model, such as camera freezing.

  • The following issues have been addressed:
  • Choosing negative values for Exposure compensation in the RETOUCH MENU > NEF (RAW) processing display did not have the desired effect.
  • Continued scrolling of the menus for some languages would cause the camera to freeze.
