z How to use the AEL button in manual mode
While you press and hold the AEL (AE Lock) button, the exposure determined by the meter is locked as the
standard exposure (0.0Ev). Changing the composition on the LCD monitor and in the viewfinder while
holding the AEL button causes the exposure within the spot metering circle to continually shift to match the
movements and the display indicates the difference between the standard exposure determined by the meter
and the exposure within the spot metering circle.
The following 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 the composition is changed in the
viewfinder, the exposure within the spot metering circle is 0.7Ev more than the set exposure, thereby
making it 1.7Ev more than the standard exposure determined by the meter.
