3.3 Measuring light – Exposure Metering
1. Exposure mode mark is displayed when the exposure mode button
A 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 A to enter
the setting.
Exposure Warnings
With an inappropriate exposure setting, when shooting subjects that
are too light or dark, the user is warned by the ashing external LCD or
the LCD inside the viewnder.
At such times, the correct exposure cannot be obtained.
Warnings that the exposure is outside the metering range
• Program AE (P)
The shutter speed and f-number blink.
• Aperture priority AE (Av)
The shutter speed blinks.
• Shutter priority AE (Tv)
The f-number blinks.
• Manual mode (M)
The exposure metering value difference is displayed.
Average/spot auto
exposure metering
Exposure metering is performed after automatically
selecting average/spot exposure metering.• Depending
on the subject conditions, center-weighted 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
exposuremetering
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.
NOTE:
you can change the amount of
time the metered value is shown by
entering Custom Settings C-04.
