Hi, I'm new to Fuji and new to this forum. I have a question about the af-c custom settings on my new X-T2 camera. How do these work/interact in combination with the "single point", "zone" and "wide/tracking" settings? For example, suppose I would like to use custom setting 5. Do I have to, e.g., select "zone" or "wide/tracking" so that the custom setting 5 actually works?
