Nikon Rumors, just reported that Nikon has just released firmware updates for the D4, D800, and the D800e. One of the main fixes implemented is the lockup issue in which the Nikon D800 locks up and the only way to reset it is to take the battery out.

Nikon D4 Firmware Update A:1.01 / B:1.01

  • When a still image was captured while viewing existing images in playback mode, the monitor turned off, the memory card access lamp glowed steadily, and, in some rare cases, the camera ceased to respond to operations. This issue has been resolved.
  • When network functions were used with certain settings applied, RAW images were also transferred when Network > Send file as was set to JPEG only. This issue has been resolved.
  • When an option that utilized the main command dial was selected for Custom Setting f15: Playback zoom, and an image was zoomed in or out with playback with certain settings applied, shooting shutter speed, aperture, and exposure compensation settings were sometimes changed. This issue has been resolved.
