76 Shooting Controls
P: Programmed Auto
In this mode, the camera automatically
adjusts shutter speed and aperture
according to a built-in program to
ensure optimal exposure in most
situations. Different combinations of
shutter speed and aperture that
produce the same exposure can be selected by rotating the
main command dial (“flexible program”). While flexible program
is in effect, a flexible program indicator (U) is displayed. To
restore default shutter speed and aperture settings, rotate the
main command dial until the indicator is no longer displayed,
choose another mode, or turn the camera off.
S: Shutter-Priority Auto
In shutter-priority auto, you choose the
shutter speed while the camera
automatically selects the aperture that
will produce the optimal exposure. To
choose a shutter speed, rotate the main
command dial. Shutter speed can be set
to values between 30s and
1
/ 4000 s.
