I find that using the distance focus control, proper F stop, and my primary lenses (PL: 8-18,12-60, 100-400) that unless I am imaging really fast stuff (like birds, or sports) that I can rely on it for focus. Yes, the G9II for sports/wildlife (fast movers) seems a bit better, but just a bit better. For me selling the Gh6 and getting a Gh7 doesn't seem to be a big benefit. If I didn't have the G9II I might feel differently. Are you selling your Gh6 to get a Gh7. I've never seen the banding because I don't shoot backlighted, extremely high contrast images that I think I can fix it in post
. I am sure the Gh7 is an amazing video camera, but so is the Gh6.
