How to lock focus between GH3 restarts.

[Tangier Clarke]

Folks, I am using a GH3 as a webcam with the Lumix 25mm lens. is there a way to make sure my focus stays locked between turning the camera on and off? I sit in the same seat in the same position, but it seems I always have to make focus adjustments every time I turn the camera on and yet I always have the camera in manual focus mode.
