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).
