"_" How to use the AEL button in manual mode
While you press _,ndhold the AEL (AE Lock) button, lhe exposure delelmined by tile metcr is locked as tile
standard exposure (0.OEv). Changing the composition on lhe LCD monitor and in the view finder while
holding the AEL button causes the exposure within the spot mctering circle to continually shift to match the
movements and the display indicates the dill?rcncc between the standard exposure determined by the meter
and the exposure within the spot metering circle.
The lollowing illustrations show a case where the set exposure specified by the photographer is 1.0Ev more
than the locked standard exposure determined by the meter. When tfie composition is changed in the
view finder, the exposure within the spot metering circle is 0.7Ev more than the _t exposure, thereby
making il 1.7Ev more than the standard exposure delermined by tile meter.
