Shooting in Aperture
Priority/Manual Expo-
sure Mode
When the mode dial is set to Aperture Priority
Mode, you can set the aperture and shutter
speed manually for shooting.
In A/M Mode, both Aperture Priority Mode
and Manual Exposure Mode are available.
If only the aperture is set, the shutter speed
is automatically set according to the aperture
(Aperture Priority Mode). I
f the shutter speed is also set, you can take
pictures with the shutter speed and the aper-
ture set at the time of shutter speed setting
(Manual Exposure Mode).
The aperture can be selected from Open,
Half, and Minimum.
The shutter speed can be selected from 1/
2000, 1/1000, 1/500, 1/250, 1/125, 1/30, 1/
15, 1/ 8, 1/4, 1/2, 1, 2, 4, 8, 15, and 30 sec-
onds.
Lowering the aperture value (f-number) blurs
the background and highlights the object.
Increasing the aperture value makes the
focus clear for both near and far objects.
Increasing the shutter speed allows you to
take a picture as if a quick-moving object
were stopped momentarily. Lowering the
shutter speed allows you to shoot the track of
a moving object because any motion can be
expressed as a flow.
The up/down dial is useful for setting in Aper-
ture Priority Mode.
• The actual aperture value depends on the
zoom position.
• The diaphragm is driven when the shutter
release button is fully depressed.
