Nikon has recently released an upgrade to the firmware of the Coolpix P600 camera, to version 1.2. This is not a major upgrade, and does not provide any new features. Its only stated purpose is to correct a problem that prevented recharging of the camera’s battery when it had been fully depleted. So, if you have not had problems with charging your camera’s battery, you can probably skip this update with no problem. But if you like to have the latest version of the firmware, just in case it could help with this or some other issue, it is now available. Here is a link to the site where Nikon makes the download available.
