xt4 Moire problem in hd video.Has anyone had a problem with moire in the xt4 shooting video in FHD? for me its crazy bad, and renders FHD useless (pretty much). Im so disappointed as for me its a camera upgrade coming from a panasonic G6 (which had minimal moire in HD). I've had the camera only two days and wondering if it needs to go back. Any ideas??
