I have been using the 1-area auto focus mode and moving the autofocus area (medium size square) to where I want to focus. It works pretty well. What does it do when you enlarge the focus area (square)? When you make it as large as it goes (which is a pretty large portion of the screen), does everything get focused in the entire area or is the center of the area more in focus and gets less sharp as you go towards the border?? Does that make sense? Also, what would the 23-area mode be useful for? I can't see how it could be useful compared to 1-area and the GX7 owners manual is pretty much useless. Thanks!!
