I was curious what others have found successful in auto focus settings for capturing quick, non-setup candid images, street photography in particular. It would seem that Panasonic's 23-Area setting, where the camera selects the focus spot automatically might give generally good results. I am so accustomed to specifying the precise focus spot, that I've never relied on the camera to do that work for me. Obviously, with street photography, especially hip shooting where you're not in precise control of composition and focus point, auto focus can be really helpful - especially coupled with deep depth of field. What settings and techniques have you folks found effective for auto focus with street photography?
