Autoexposure Lock

When center-weighted metering is used, an area in the center of the frame is assigned the greatest weight when determining exposure. Similarly, when spot metering is used, exposure is based upon lighting conditions in the selected fo- cus area. If the subject is not in the metered area when the picture is taken, exposure will be based on lighting conditions in the background, and the main subject may be under- or over-exposed. To prevent this, use autoexposure lock:

1Select exposure mode P, S, or A and choose cen- ter-weighted or spot metering (exposure lock

has no effect in exposure mode M). If using cen- ter-weighted metering, select the center focus area with the multi selector ( 53).

2Position the subject in the selected focus area and press the shutter-re- lease button halfway. With the shutter-release button pressed halfway and the subject positioned in the focus area, press the AE-L/AF-Lbutton to lock exposure (and focus, except in manual focus mode). Confirm that the in- focus indicator (●) appears in the viewfinder.

While exposure lock is in effect, an AE-Lindicator will appear in the view- finder.

3Keeping the AE-L/AF-Lbutton pressed, recom- pose the photograph and shoot.
