USING BUILT-IN TTL FLASH 48
-Do not touch the flash when firing
it
; normal operation
can make
it
quite
hot.
e Never fire the flash more than 20 consecutive times at
intervals
of
5 sec. or shorter. Firing continuously more
than 20 times may impair flash performance. After
each major flash shooting, let the flash rest at least
10
minutes before firing again.
When you continuously fire the flash, the camera's
handgrip may become hot due to normal operation.
In
this case,
it
will take longer for the ready-light come on
because the flash automatically stops charging for a
while.
-When battery voltage decreases due
to
low tempera-
ture or weak batteries, the ready-light may turn off even
after
it
lights up once. Before shooting, make sure the
ready-light
is
on.
eWhen the built-in
TIL
flash
is
up, an accessory Speed-
light will not
fire.
When using a Speed light, store the
built-in
TIL
flash
in
the down position.
e Before shooting, make sure your subject
is
within the
flash shooting distance range.
-Usable film speed range for the bui lt-in
TI
L flash
is
I
SO
25 to ISO 800.

Notes
on
selecting aperture
In
aperture-priority auto and manual exposure
mode
eThe larger the aperture (the smaller the f-number) you
select, the greater the maximum shooting distance,
whereas the smaller the aperture (the larger the
f-number), the less the maximum shooting distance.
-When subject distance remains the same, as the aper-
ture increases, the depth of
fie
ld becomes smaller. The
smaller the aperture, the greater the depth of field.
In
shutter-priority auto exposure mode
e With a slower shutter speed, a smaller aperture
is
auto-
matically selected, causing a shorter shooting distance
range.
e
lf
shutter speed remains the same, as background
brightness increases, the aperture becomes smaller.
To
perform flash shooting in daytime, Nikon recommends
that you switch
io
aperture-priority auto
or
manual
exposure mode in order to select a wider aperture for
greater flash shooting distance.
