1. Exposure mode mark is displayed
when the exposure mode button
is pressed. Since three different
exposure modes are displayed
sequentially when either the front
or rear dial is turned, select an
appropriate exposure mode.
2. Press the SET button or exposure
metering mode button to enter the
setting.
Average/spot auto
exposure metering
Exposure metering is performed after automatically selecting
average/spot exposure metering.
• Depending on the subject conditions, centerweighted average/
spot exposure metering is selected automatically, and the
correct exposure is measured.
• Spot exposure metering is automatically selected when the
brightness of the spot exposure metering range becomes
darker than the brightness of the entire screen.
• If there is very little difference between the spot exposure
metering value and center-weighted average exposure
metering value, the correct exposure level is obtained as the
intermediate value.
Center-weighted
average/spot exposure
metering
The average brightness of the entire screen is
measured, emphasizing the center of the screen.
Center spot exposure
metering
The brightness of an area equivalent to 7.6% at screen center is
measured, and the exposure is determined. The circle at screen
center serves as a general guideline. This mode is suited to
measuring subjects with strong contrasts or measuring only
screen portions.
