Using the Center-Weighted Metering
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.

Using the Spot Metering

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.
Exposure is set separately from focus point.
Exposure is set in accordance with focus point.
