EOS 5D Mark IV: Exposure compensation

The EOS 5D Mark IV features up to five stops of exposure compensation. However, when looking through the viewfinder or on the top LCD panel, only 3-stops of range can be seen on the scale. To make use of the full 5 stops of compensation, press the Q button to access the Quick Control display screen on the rear LCD or set the compensation through the camera menu.
