When you set Dynamic Area autofocus on the D300, a
grouped pattern of sensors is used to obtain final focus
information, though the initial focus is obtained with the

considers in addition to the currently selected sensor is
selected with this function. Basically, you choose the “range”
of sensors beyond the initially selected sensor that the camera
uses to focus.
