I generally agree, but going from f/8 to f/16 generally buys you very little, perhaps nothing at all noticeable, from a depth of field point of view, and costs you one stop in either shutter speed or ISO. No need to go past f/8 in my book. I never go past f/11 anymore.

Also, at f/16 I think one starts seeing some diffraction effects on a crop sensor camera.
