This morning Panasonic released firmware v1.2 for the LX-3.
Issues addressed are:
1. Improved white balance flash mode setting when DMW-FL220 is connected.
2. Proper setting of shutter speed on iA mode and Scene mode when OIS is turned ON.
3. Proper Exif information in the JPEG picture file.
You can download the firmware directly from Panasonic here.
