Hello, It's very strange that my GX-7 does AE-Lock with half press shutter. Searched through the menus but found nothing to disable it. It doesn't look like normal AE-Lock because screen brightness remains constant (it's brightness changes with lighting conditions), but exposure values (aperture, shutter) doesn't change accordingly. With AE-Lock button screen brightness changes accordingly to lighting conditions - it becomes dark or bright . Is that a bug or something I can change in the menus??
