My GX7 has C1, C2 and C3. I notice most of the larger Panasonic cameras have at least 1 of these custom settings positions on the dial. Mine are sitting there empty as I haven't programmed them for anything yet. I'd like to get some ideas on how people are using these dial positions and maybe I can find a way to utilize them. So, what do you have your custom dial positions set up to do?
