4. MANUAL EXPOSURE
In the manual mode, both the shutter speed and aperture are set manually.
1. Set the Shutter Speed Selector to any speed you want to use.
2. Set the Aperture Ring to any f-number you want to use.
3. Look through the Viewfinder and press the Shutter Release halfway down.
4. If the shutter speed you selected was 1/125 sec. but two LEDs turn on
at the same time, one opposite the number 125 and the other opposite the
number 30, and the one opposite 30 blinks as shown here, the correct
shutter speed for the aperture you selected is 1/30 sec.
5. You must either turn and set the Aperture Ring so that you can see only
one unblinking LED opposite the number 125 or set the Shutter Speed
Selector to 30 so that the LED opposite 125 turns off and the one opposite
30 stops blinking and remains on.
6. After making the correct adjustment, take your picture by pressing the
Shutter Release gently down.
7. You can easily make exposure compensation by taking advantage of the
function just described. In the case just illustrated, you can
intentionally underexpose by 1 EV by setting the Shutter Speed Selector to
60 (1/60-sec.) or overexpose by 1 EV by setting it to 15 (1/15-sec.)
