appropriate exposure mode.
2. Press the SET button or exposure
metering mode button to enter the

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.
