QR codes that appear when connecting the camera to a smartphone
(p.W-12, W-33).
For the operating system versions supported by Camera Connect,

refer to the download site of Camera Connect.
When an NFC-compatible smartphone is touched to the camera

before installing Camera Connect, the download screen of Camera
Connect will be displayed on the smartphone.
Interface or functions of the camera and Camera Connect are

subject to change for firmware update of the camera or application
update of Camera Connect, Android, iOS, etc. In such a case,
features of the camera or Camera Connect may differ from sample
