Metering is weighted at the center of the
screen. Use this metering when you want
to compensate the exposure by
experience, instead of leaving it to the
camera. The illustration shows that
sensitivity increases as the pattern height
increases (center). This mode does not
automatically compensate for backlit
scenes.
With spot metering, brightness is
measured only within a limited area at the
center of the screen as shown in the
illustration. You can use this in
combination with the AE lock (p.142)
when the subject is extremely small and
proper exposure is difficult to obtain.

Linking AF Point and AE During Multi-Segmented

A
Custom] menu, you can
link the exposure and focus point in the focusing area during multi-
segment metering. The default setting is [1 (Off)].
1
Off Exposure is set separately from focus point.
2
On Exposure is set in accordance with focus point.
