C.Fn-17-1: The focusing point activation area expands by one point all around the manually-selected focusing point. A total of 7 focusing points become active. This setting is effective for when only one manually-selected focusing point is unable to focus track a subject moving irregularly.

C.Fn-17-2: The camera automatically sets the focusing point activation area to 1, 7 or 13 points to suit the lens focal length, AF mode, and the subject’s speed during predictive AF. (→p.44) This is effective when the subject’s movement is unpredictable.
