Av: Changing the Depth of Field
• When using a high aperture value, note that camera shake can
occur in low light scenes.
A higher aperture value will make the shutter speed slower. Under
low light, the shutter speed can be as long as 30 sec.
In such cases,
increase the ISO speed and hold the camera steady or use a tripod.
• The depth of field depends not only on the aperture, but also
the lens and subject distance.
Since wide-angle lenses have a wide depth of field, you need not set
a high aperture value to obtain a sharp picture from the foreground
to the background.
On the other hand, a telephoto lens has a narrow
depth
of field.
And the closer the subject, the narrower the depth
of field. A farther
subject will have a wider depth
of field.
~ Set the aperture so that the shutter speed display does not
blink in the viewfinder.
If you press the shutter button halfway and change
the aperture while the shutter speed is displayed,
the shutter speed display will also change to
maintain the same exposure (amount
of light
reaching the imaging sensor). If you exceed the
adjustable shutter speed range, the shutter speed
display will blink to indicate that the standard
exposure cannot
be obtained.
If the picture will
be too dark, the 30" (30 sec.) shutter speed display
will blink. If this happens, turn the
<B > dial to the left to set a lower
aperture value or increase the ISO speed.
If the picture will be too bright, the 4000 (1/4000 sec.) shutter speed
display will blink. If this happens, turn the
<B > dial to the right to
set a higher aperture value or decrease the ISO speed.
