• The aperture range depends on the lens.
• The aperture value is adjusted
in
1/3
EV increments. You can set this exposure step to 1/2
EV
increments with [Exposure step]
in
the
IlOl
Recording menu (page 98).
•
If
the proper exposure is not obtained after making the settings, the shutter speed on the LCD monitor and
in
the viewfinder flashes when the shutter button is pressed halfway down. You can shoot
at
this point, but
adjusting again is recommended.
• When the flash is pulled up, the flash fires regardless
of
the amount
of
ambient light (page 73).
• When using the flash,
if
you close the aperture (a larger F-number), the flash light does not reach a distant
subject. Opening the aperture (a smaller F-number) is recommended.
• If you close the aperture (a larger F-number), the amount
of
light passing through the lens is decreased
and the shutter speed becomes slower. Using a tripod
is
recommended.

Shooting techniques
The depth
of
field is the in-focus range. Opening the aperture makes the depth
of
field shallower (the in-
focus range becomes narrower) and closing the aperture makes the depth
of
field wider (the in-focus
range becomes wider).
Open
the
aperture
The subject is sharpened with
its background blurred.
Close the aperture
Over a wide range, both
nearby and faraway subjects
are brought into focus.

Adjust the aperture to suit your purpose, either to sharpen the specific area
of
image, or to focus on the
entire image.
