Multi segment metering
Except for exposure mode M, the exposure is automatically acquired
(Automatic exposure).
Based on the exposure acquired by the automatic exposure, you can
perform exposure compensation, depending on your preference. You can
make the entire image brighter by shifting it to the + side. The entire image
becomes darker when you shift it to the – side.
The screen of this camera is equipped
with 39 honeycomb sharped metering
elements and one metering element that
covers the surrounding area. These
elements work in sync with auto focus,
allowing the camera to accurately
measure the position and brightness of
the subject in order to determine the
exposure.
• In multi segment metering, if the focus is locked, the exposure (the
shutter speed and the aperture) is locked simultaneously (only when
Single-shot AF or Automatic AF).
