When an aperture value is set, the camera
automatically sets a shutter speed so that the
depth of eld in that combination can be used.
When the diaphragm (aperture) is opened:
The depth of eld becomes shallower.
⇒A shallower depth of eld is useful when you
wish to keep your main subject in sharp focus
against the background intentionally blurred.
When the diaphragm is closed: The depth of
eld becomes deeper.
⇒A deeper depth of eld is preferable when
you wish to capture your main subject as well
as the background in sharp focus.
①Align the “A” mark of the Shutter Speed
Dial with the indicator line.
②Rotate the Aperture Control Ring and set
to a preferred aperture value.
●When a depth of eld is deep: Objects in
front of and behind the main subject are
captured in sharp focus as well.
●When a depth of eld is shallow: Objects
in front of and behind the main subject are
blurred.
What does the term “depth of eld” mean?
When a lens is focused precisely on a main
subject, there is a depth (range) where the
background and the foreground of the main
subject can be in focus as well. This depth is
called “a depth of eld”.
[Characteristics]
(1) Depths of eld become shallower as you
open apertures, while they become deeper
as you stop down the aperture of your taking
lens.
(2) Depths of eld become deeper as working
distance become longer, while they become
shallower as your working distance becomes
shorter.
(3) The front depth against your main subject (the
range closer to you) is shallower than the rear
depth (the range away from the main subject).
(4) When an aperture value is the same, a depth
of eld becomes deeper with a lens having
a shorter focal length, while a depth of eld
becomes shallower with a lens having a longer
focal length.
③When the Shutter Release Button is pushed
halfway, the camera starts light measuring.
⇒A shutter speed is set automatically and
displayed in the viewnder and in the mode
display. A proper exposure value is obtained
when the shutter speed indicator is lit.
Aperture Priority AE
*The Shutter Speed Dial will be locked at the
position marked “A”.
●Depth-of-eld scale of the lens
When your working distance is 2
meters and the aperture value is set
at F/11, subjects within the range
of 1.5 to 3 meters are captured in
tolerably sharp focus.
*The depth-of-eld scale is convenient for taking
pictures at estimated distances.
In low light conditions, shutter speeds become slower
depending upon aperture values. Therefore, the use
of a tripod is recommended in such photographic
conditions.
● When the shutter speed indicator and the “ ▲”
mark are ashing, they indicate the setting is “over
(exposure)”. Stop down the aperture in such a case.
● When the shutter speed indicator and the " ▼”
mark are ashing, they indicate the setting is “under
(exposure)”. Open the aperture in such a case.
