I have a special application (use) which requires the camera to be permanently fixed at infinity focus. Is there a way to defeat the Autofocus on the Panasonic Lumix DMC-FX150? This would serve to decrease the shutter lag time and increase battery life.
Some cameras, depending on the focusing technology used, can be fixed at infinity by simply covering a sensor port with tape, or the like.
You can cover the sensor with a tape or you can just off the sensor in the menu option.
