s, or the shutter can be
held open indefinitely for a long time-exposure (
). Aperture can be set
to values between the minimum and maximum values for the lens. Using the
electronic analog exposure display in the viewfinder, you can adjust exposure
according to shooting conditions and the task at hand.
To take photographs in manual exposure mode:
1
Rotate the function dial to M.
2
Rotate the main command dial to choose a shutter speed, and the sub-
command dial to set aperture. Check exposure in the electronic analog
exposure display (see opposite), and continue to adjust shutter speed and
aperture until the desired exposure is achieved.
3
Frame a photograph and shoot. If shutter speed is set to
, the shutter
will remain open while the shutter-release button is held down.
Non-CPU Lenses
If a non-CPU lens is attached in manual exposure mode,
will appear in the aper-
ture displays in the control panel and viewfinder. Aperture must be adjusted manually
using the lens aperture ring. The camera exposure meter can not be used, and expo-
sure will not be displayed in the electronic analog exposure display.
