46 Reference: P, S, A, and M Modes/Exposure

If the subject is not in the metered area when center-weighted or spot metering is used,

exposure will be based on lighting conditions in the background and the main subject may

not be correctly exposed. This can be prevented by using autoexposure lock.

Adjusting Shutter Speed and Aperture

While exposure lock is in effect, the following settings can be adjusted without altering the metered

value for exposure.

The new values can be confirmed in the viewfinder and shooting information display. Note that the

metering method can not be changed while exposure lock is in effect (changes to metering take

effect when the lock is released).

12—AE-L/AF-L ( 77)

This option controls the behavior of the AE-L/AF-L button.

13—AE Lock ( 77)

This option controls whether the shutter-release button locks exposure.

Autoexposure Lock

Controls used AE-L/AF-L button

Select mode P, S, or A and choose center-weighted or spot metering (exposure lock has

no effect in mode M).

Position the subject in the selected focus area (when using

center-weighted metering, position the subject in the center

focus area). Press the shutter-release button halfway and con-

firm that the in-focus indicator (z) appears in the viewfinder.

Then, keeping the shutter-release button pressed halfway and

the subject positioned in the selected focus area, press the AE-

L/AF-L button to lock exposure.

While exposure lock is in effect, an EL indicator will appear in

the viewfinder.
