I posted this in my Exploring Gx8 thread, but this is the reason 4K video was so important to me. Your out on a shoot, and your filming that once in a lifetime event and just don't have time to grab the camera hanging on your side for stills leaving the video camera to do its "thing". But then you remember, Photoshop with the "import video to layers" and bingo you have an 8 meg. image for publication. 4K video is insurance that you get something usable if you are required to shoot both stills and video and can't jump from one mode/camera to the other.
