±0 EV
(E button pressed)
At values other than ±0.0, the 0 at the
center of the exposure indicators will
flash (exposure modes P, S, and A only)
and a E icon will be displayed in the
viewfinder and control panel after you
release the E button. The current value
for exposure compensation can be confirmed in the exposure
indicator by pressing the E button.
Normal exposure can be restored by setting exposure
compensation to ±0.0. Exposure compensation is not reset
when the camera is turned off.
A
Exposure Mode M
In exposure mode M, exposure compensation affects only the
exposure indicator; shutter speed and aperture do not change.
A
Using a Flash
When a flash is used, exposure compensation affects both flash level
and exposure, altering the brightness of both the main subject and the
background. Custom Setting e3 (Exposure comp. for flash, 0 300)
can be used to restrict the effects of exposure compensation to the
background only.
