when the image is underexposed (insufficient light)
or overexposed (too much light) and the correct
exposure cannot be obtained.
z Some aperture values cannot be selected
depending on the zoom position.
z In this mode, the maximum shutter speed with
synchronized flash is 1/250 second. The aperture
value setting may therefore be changed
automatically to match the synchronized flash
speed even if its value was set previously.

The larger the aperture value, the smaller the lens
aperture.

Manually Setting the Shutter

shooting fireworks and other images where it is
difficult to set the correct exposure automatically.

selected shutter speed and aperture value. If the
flash is set to
(Flash on, with red-eye
reduction) or (Flash on), the LCD Monitor will
always appear bright.
z When you press the shutter button halfway, the
difference between the standard exposure* and the
selected exposure appears on the LCD monitor. If
the difference is more than 2 stops, "-2" or "+2"
appears in red on the LCD monitor.
* The standard exposure is calculated by the AE
function according to the selected metering
method.
About the Safety Shift
When the Safety Shift has been turned on (p. 67), it
may not be possible to obtain an appropriate
exposure with a shutter speed and aperture value
that have been set manually. In such a case, the
settings will automatically be adjusted so that they
fall within the range for an appropriate exposure.
