Shutter-Priority Auto
When the camera is set to shutter-priority auto, shutter speed
can be chosen by rotating the command dial. Options range
from 8 s to 1 /
1000
s in increments of one step.
Manual
In manual exposure mode, you can choose an aperture be-
tween maximum and minimum aperture (in increments of 1 /
3
of a step), and a shutter speed of “bulb” or values between 8 s
and 1 /
1000
s (in increments of one step). Follow the steps below
to set shutter-speed and aperture in manual exposure mode:
1 After setting the exposure mode to manual, release the
button.
2 Press the button again to select ei-
ther shutter speed or aperture in the con-
trol panel shutter-speed/aperture display, or
in the LCD monitor, where the selected
item is shown in green. The item selected changes each
time the button is pressed.
When the shutter-speed is set to bulb (manual exposure mode only), the
shutter will remain open while the shutter-release button is pressed (maxi-
mum exposure 60 s). Use of the remote shutter-release cord MC-EU1
(available separately) and a tripod is recommended.
Note that if the shutter is open for longer than 1 /
4
s at any setting, noise
may appear in the final photograph.
Long time exposure
Shutter speed displayed
in LCD monitor and
control panel (shutter
speeds of
1 /
4
s or more
are shown in the LCD
monitor in yellow to
indicate that noise may
appear in the final
photograph)
Rotate
If the selected shutter speed would result in the photograph
being over- or under-exposed, the shutter speed displayed in
the control panel and LCD monitor will flash when the shut-
ter-release button is pressed halfway. Choose another setting
and try again.
