Exposure can be altered from the value suggested by the camera by setting both shutter speed and aperture to values other than A.
M will appear in the display.
If AUTO is displayed in red, press a function button (by default, Fn2/AUTO) to exit auto mode.
The manual exposure display includes an exposure indicator that shows the amount the picture would be under- or over-exposed at current settings.
At settings other than 180X, shutter speed can also be adjusted in increments of 1/3 EV by rotating the command dial.
For information on the role of the command dial when the camera is used with lenses not equipped with an aperture ring, see "Lenses with No Aperture Rings".
