Thanks for the response. Is it not advisable to keep the Af at 0db and adjust the sensitivity based on the subject?
Is there kind of a golden rule for a level on the AF? It seems when I do -20 db for both it seems quite low, even when I crank the zoom.
I found -18db af and -12 db for sensitivity worked while when I tested it on myself.
Is it bad to have a large discrepancy in Af and sensitivity ?
