4. Turn either the shutter dial or lens aperture ring
until a single bar is displayed in the center of the
bar graph.
5. When the shutter release button is depressed
halfway, the shutter speed, approximate aperture
and bar graph will be displayed in the viewfinder.
• When the bars are displayed to the [ + ] side on the bar
graph, it indicates overexposure and when the bars are
displayed to the [ - ] side, it indicates underexposure.
• Moving one bar on the bar graph indicates 1/3 step
(0.3EV). However, when under or over exposure is set
beyond + 3 or - 3 steps (3EV), [ + ] or [ - ] indicator will
blink.
• In flash photography, when you use the flash sync shut-
ter speed of 1/60 second or a non-dedicated external
flash unit, set the shutter dial to the [ X ] (1/60 of second)
position.
* Exposure Warning
If the subject is too bright or too dark, the selected shutter
speed will blink in the viewfinder as a warning as shown.
When the subject is too bright, choose a smaller aperture;
when it is too dark, choose a larger aperture. When the
shutter speed indication stops blinking, you can take a pic-
ture. If both shutter and aperture blink, It means that the
exposure is out of metering range, unable to obtain a cor-
rect exposure even if the aperture is adjusted. Select a
darker subject or use a flash if it is too dark.
