Hi all, just wondered if anyone else had this problem and how to fix it? My G5Xm2 shows the scene I want to take, perfectly - but only in landscape orientation. As soon as I turn it to portrait orientation, the screen goes dark, almost as if the ND filter kicks in! This only started happening a couple of outings ago. I've looked through menu options a number of times but for the life of me can't find where I might inadvertantly changed an option in error. Otherwise I really love the camera and going out with it is so liberating. Cheers
