I've had the GH5 for a few weeks now and for the video work I do I don't really use autofocus so it's working out great! However I'm having this issue with the LCD brightness. On my first shoot with it I realized I had the auto LCD brightness on and it was driving me crazy! So I went into the menu and changed the monitor luminance from Auto to 1*. However, if I don't change the focus, zoom, or touch any other buttons for a few minutes the screen gets darker. The second I touch anything it brightens up again. I figure there was some kind of power save setting turned on. I found the economy setting and everything was set to off. I'm sure there is another setting I'm missing but I can't figure it out! Any ideas?
