Excuse my answering your question although not directed at me.
The LX5 resets back to default after powering on or off. The only way you may be able to circumvent this is by setting one of a number of user defined Custom Settings available within the camera. It may or may not work with AF settings. I personally have not tried to do this, but have defined a number of custom settings, for color, picture size, bracketing, etc.
I still love this camera and am happy that I now have it along with the GF1.
