SOME NOTES ABOUT YOUR NEW FLASH
This dedicated Vivitar Electronic Flash Unit
is
designed specifically for Nikon 2020 or
F501
Auto Focus
35mm
SLR
cameras. It provides automatic through-the-lens (
TIL
) flash exposures
in
addition
to
manual
flash.
F~rthermore
.
when the light
is
too dim for the camera
to
auto focus. the flash 's built-in Illuminator
automatically
provides a source
of
light for the camera to auto focus. This allows you
to
take sharply
focused pictures
in
very low light
or
even total darkness.
IMPORTANT: The auto focus mode selector
on
the front of the camera must
be
in
the
·s
· setting
in
order
for the Auto Focus
Illuminator to function.
There are
two
modes
of
automatic TTL flash operation: Program and Aperture Priority.
In
the Manual
Mode, there are two manual flash power levels of FULL and -4
(1
/16th of FULL power). The
-4
setting
is
ideal for fast recycle lime when auto exposure
is
not needed.
A SIMPLE TTL FLASH TEST
To verify the TTL exposure operation,
an
actual exposure must
be
made with the flash attached
to
the
camera and
film loaded
in
the camera. For test purposes, a light toned piece
of
paper can be positioned
at
the film plane
as
a film substitute and the camera back must
be
closed. Please note that light toned paper
may give incorrect responses due
to
differences
in
its reflective qualities versus actual film.
In
any case.
an
actual flash exposure must be made
by
depressing the camera shutter release button. When the flash
is
fired and there
is
insufficient light output, the lightning symbol in the viewfinder and the Under Exposure
LED (1
0)
on
the flash will blink. In addition, when the flash Tone Switch (20)
is ON, there will be a beeping
sound.
If there
is
enough light, no warnings will occur. (Nikon camera systems only warn
of
flash under
exposure
.)
