Description
C.Fn-16-1:In case the subject’s brightness changes suddenly and the
current shutter speed-priority AE or aperture-priority AE
setting becomes unsuitable, the shutter speed or aperture
is shifted to obtain a suitable exposure.
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.
