Nikon has announced firmware updates for the D3X, D3, D700 and D300S which are available for immediate download. The firmware fixes a number of issues described below.

  • Support for 64 GB memory cards has been added.
  • When the Multi-Power Battery Pack MB-D10 was used with AA batteries, the battery indicator showed that MB-D10 batteries were exhausted or power supply switched to the battery inserted in the camera even when sufficient charge remained with the MB-D10 batteries. This issue has been resolved.
  • When some memory cards were inserted in the camera, “CHA” was displayed in the top control panel and images could not be captured. This issue has been resolved.
