Nikon has released firmware updates for the Nikon D300, D300s, D700 and P7700.
The firmware update for the Nikon Coolpix P7700 includes the following improvements:
When shooting with shooting mode set to M (manual) with Flash, and the ISO sensitivity set to Auto, ISO 80-200, ISO 80-400, or ISO 80-800, ISO sensitivity was sometimes not locked at ISO 80 and a different ISO sensitivity was sometimes applied. This issue has been resolved.
