A Storing the Focus Position To save the focus position when the camera is turned off, select [On] for [Save focus position] in the setup menu. Note that this increases camera startup times (in addition, if the temperature, zoom position, or other conditions change while the camera is off, focus may resume from a different position when the camera is turned on).
