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. However, bear in mind that applying an earlier build might not always be possible. 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. 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. Confirm that the firmware has been updated to the new version.

If the standby timer expires after focusing, the focus position will no longer change when the timer is reactivated.
