Choose aperture and shutter speed.
Rotate the main command dial to choose a shutter speed, and
the sub-command dial to set aperture. Shutter speed can be
set "p" or to values between 30 s and
shutter can be held open indefinitely for a long time-exposure
(A, pg. 111). Aperture can be set to values between the
minimum and maximum values for the lens. Check exposure
in the electronic analog exposure displays (see page 111), and
continue to adjust shutter speed and aperture until the
desired exposure is achieved.
