ACCESSORIES-continued-------------
Electronic Flash Units
Nikon
Speed
lights
are
dedicated
electronic
flash
units
and
provide the
perfect
complement
to your
F3
High-Eyepoint
camera.
Just
set
the
aperture and flash output is measured
through
the
lens
for
correct
exposures regardless
of the lens
in
use.
Speedlights SB-16A and 17
The SB-16A and SB-17 mount directly on
the
camera for auto-
matic
TTL
flash exposure control.
The
SB-16A
features
two
flash
heads for more natural bounce-flash portraits: main head
tilts 90°
and
rotates 270°;
the
secondary
head faces
straight
ahead
to
provide catchlight
in
subject's eyes. Main
head
zooms in and out
to
match the coverage of 28, 35, 50 and
85mm
lenses
with a guide number of 32 (ISO
100
and meters)
or
105 (ISO
100/feet).
The light,
compact SB-17 has a gUide
number of 25
(ISO
lOO/meters) or 82 (ISO 100/feet) and fea-
tures a rotating
flash
head and tilting 90° flash
tube
module
for convenient
bounce flash.
Speedlight SB-21A
The SB-21A lets you
use
TTL
automatic
exposure for macro
photography, and a
convenient
focus illuminator
ensures pin-
point
focus
adjustment.
The
flash
head
offers
a
65°
horizon-
tal
and 85° vertical angle of coverage, and a wide illumination
panel
lets
you shoot
flash-to-subject
distances closer than
40mm
(approx.
1.6
in.). SB-21A can be used with an
exter-
nal power source (AC or DC). Guide number
is
13 (at ISO
lOO/meters)
or 43 {at
ISO
100/feet) with
internal
batteries, and
15 (or
49) with external power source.
