My new GH1 has just become a GH17... I was testing it by shooting in a big white room and noticed a couple of large bands with move with the camera... here's a screenshot. http://moviesoundstudios.com/gh17-stripes.jpg Is this a bad camera, or am I doing something wrong? I also shot a green hallway with carpet and noticed the horizontal stripes. I've tried two lenses, and different ISO/exposure settings... brighter looking shots help, but I still notice it. Anyone seen anything like this??
