Changes:

- Users can now choose the band (2.4 or 5 GHz) for the host SSID when connecting to wireless networks via a WT-6 wireless transmitter attached to the camera. The band is listed in Connection Wizard network-selection dialog and post-connection in the Wired LAN/WT display.
- Autofocus for viewfinder photography has been improved.
- Focus-point selection now works smoothly even if the user abruptly switches directions on the multi selector or sub-selector.

Fixed the following issues:

- Autofocus sometimes produced unpredictable results when used with certain AF-S lenses with maximum apertures faster than f/2.8.
- Instead of flashing, the network indicator would remain lit when an Ethernet connection was established.
- The WT-6 wireless transmitter could not be used to join wireless networks with SSIDs containing a space, semicolon (“;”), ampersand (“”), or backslash (“”).
- The over- and under-exposure indicators in the viewfinder were reversed when +0- was selected for Custom Setting f9 (Reverse indicators) in the CUSTOM SETTING MENU.
- The exposure indicators were slow to refresh when shutter speed, aperture, or ISO sensitivity were adjusted using the main- or sub-command dial.
- If, when Focus point and AF-area mode was selected for Custom Setting a5 (Store points by orientation) in the CUSTOM SETTING MENU, the standby timer expired with the camera in portrait (tall) orientation and the camera was then rotated to landscape (wide) orientation before the standby timer was reactivated, the camera would not restore the AF-area mode previously selected for landscape orientation, but would instead switch to the AF-area mode selected when the camera was in portrait orientation.
- The following would not be immediately updated to reflect the true number of exposures remaining after pictures were deleted: the number of exposures remaining shown in the top control panel when the camera was off, and the frame-count display in the rear control panel when Frame count was selected for Custom Setting d12 (Rear control panel) in the CUSTOM SETTING MENU.
- The AF fine-tuning options item could be used to store only one set of fine-tuning values for AF-S NIKKOR 180-400mm f/4E TC1.4 FL ED VR lenses: users could store either values for use with the built-in teleconverter or values for use without, but not both.

Viewing the Camera Firmware Version:

- Turn the camera on.
- Press the camera MENU button and select Firmware version in the SETUP MENU to display the camera firmware version.
- Check the camera firmware version.
- Turn the camera off.

Updating the Camera Firmware:

- Create a folder on the computer hard disk and name it as desired.
- Save the downloadable file to the newly-created folder.
- Run the package to extract a .bin file (the camera firmware) to a folder named “D6Update”
- Using a card slot or card reader, copy .bin file to a memory card that has been formatted in the camera.
- Insert the memory card into the Slot 1 on the camera and turn the camera on.
- Select Firmware version in the SETUP MENU and follow the on-screen instructions to complete the firmware update.
- Once the update is complete, turn the camera off and remove the memory card.
- Confirm that the firmware has been updated to the new version. 

About Digital Camera Updates:

Updating to a newer firmware version than the one already installed on your camera can improve the device's overall performance and stability, resolve various issues, and add support for newly developed features or enhance existing ones.

On the other hand, downgrading the camera's firmware can recover its functionality in the unlikely event the currently installed version is faulty or the device's performance dropped after an upgrade. However, bear in mind that applying an earlier build might not always be possible.

It is recommended that changing the camera's firmware be performed when the new release resolves an issue that your device has been encountering, or adds a new feature (or enhances an existing one) that could prove useful for you.

This process isn't intended to be destructive, but still, it's best to save all your personal data and configurations before applying a different firmware. Moreover, make sure that the battery is fully charged and don't use the camera's buttons while the installation is in progress.

When it comes to the update method, usually, you must copy the firmware file onto a compatible memory card, insert it into the camera, and browse from the menu to the device's update section.

However, each device has various ways to enter the update mode and particular steps that should be taken for a successful upgrade, therefore make sure you read the product's installation guide.

That being said, if you consider that this firmware improves your device in any way, then hit the download button and get the desired version; if not, check with our website as often as possible so that you don't miss the update that will boost your camera's performance.

  It is highly recommended to always use the most recent driver version available.

Try to set a system restore point before installing a device driver. This will help if you installed an incorrect or mismatched driver. Problems can arise when your hardware device is too old or not supported any longer.
