Panasonic LUMIX DMC-FX8 I found the Panasonic Lumix DMC-FX7 upgrade to FX8. With a new lithium ion battery, the new camera doubles the battery life. Also, it has the Economy Mode which the LCD monitor will be turned off automatically while the camera is not in use. Also, quickened AF speed allowing taking picture easier. Seem the FX8 have overcome the weakness of the pervious FX7. What do you guy think?
