Designed
to
complement
the
versatility of
the
F3,
the
Nikon SB-12 is a
direct-mounting
electronic
flash unit
offering fully
automatic
through
-
the
-Iens flash
output
control. Even with
the
camera
on
automatic,
the
proper
synchronization
speed
of 1/80
sec.
is automatically set.
Then, while
the
shutter
is
open,
the
camera's
Silicon
Photo Diode
reads
the
light
reflected
off
the
film
and
tells
the
flash unit to
cut
itself
off
when
the
exposure
is
correct
.
With a
guide
number
of
25 (ASA 100
and
meters)
or
40
(ASA 25
and
feet),
the
SB
-
12
Speedlight
provides
just the
right
amount
of light for
subjects
located
between
0.6m-
15m
(2ft-49ft).
As soon
as
the
flash is
recycled
and
ready
to fire,
an
LED
ready
-light inside
the
finder
goes
on.
The
40
same
LED
blinks
to let you know
when
the
light is
insufficient for
proper
exposure.
And
for
those
photographers
needing
even
more
power
and
versatility, Nikon
has
created
the
SB-ll
Speed
light.
It
has
a gUide
number
of 36 (ASA
100
and
meters)
or
60
(ASA 25
and
feet)
and
gives
you a
choice
of
three
auto-
matic shooting
apertures
- I/4, £/5.6,
and
£/8
at
ASA
100.
When
used
with the F3 via a
special
TTL
connecting
cord,
it
provides
the
same
automatic
through
-
the
-Iens
control of
the
flash
exposure
as
the
SB
-
12.
Other
features
include
a
bounce
head
and
a
removable
sensor
for auto-
matic
use
with
other
cameras
.
