Für Besitzer einer Nikon F4/F4s und F-801
Das SB-20 ermöglicht matrix-gesteuerten Aufheliblitz und Aufheilbiitz
mit mittenbetonter Messung zusätziich zur normalen TTL-Blitzautomatik und Blitzautomatik ohne TTL. Matrix-gesteuerter Aufheiiblitz
erzeugt eine ausgewogene Kombination von Umgebungsiicht und
Biitzbeieuchtung, die natüriich wirkt. Detaiis werden besser
herausgestelit—ohne daß dadurch die korrekte Belichtung für den
Hintergrund verlorengeht.
Für nähere Einzeiheiten lesen Sie bitte auch die Bedienungsanieitung
zu Ihrer Kamera.
Die möglichen Biitzbetriebsarten für die einzelnen Kombinationen von
Kamera und SB-20 entnehmen Sie bitte der Tabeile weiter unten.

Zur Beachtung:
1. Bei Verwendung der AF-Illuminator-LED des SB-20 mit einem AFNikkor-Objektiv läßt sich mit Brennweiten von 25 bis 105mm
arbeiten. Dieser Bereich verschiebt sich bei Verwendung des AFTelekonverters TC-16A nach 15 bis 58mm. Der Fokussierbereich
liegt bei etwa 1 bis 8 Metern (mit AF-Nikkor 50mm f/1,8, bei
Normaltemperaturen, für ein normales Aufnahmeobjekt mit 35%
Reflexionsgrad).
2. Für indirekfes Blifzen die Kamera auf Belichfungsbetriebsart A oder
M einstellen und eine der größeren Blenden wählen.
3. Bei manueller Blitzkontrolle die Kamera auf Belichfungsbefriebsart
A oder M einstellen und die Blende von Hand wählen.

remplissant les ombres marquées et en mettant en valeur les détails
du sujet—sans perdre l’exposition correcte de l’arrière-plan.
Pour les détails, lisez attentivement le mode d’emploi du SB-20 et celui
de l’appareil.
Référez-vous aux tableaux ci-après pour les modes de flash utilisables
pour chaque combinaison appareil/SB-20.

For Nikon F4/F4S, F-801/N8008*
camera users
The Nikon Autofocus Speedlight SB-20 makes it possible to perform
Matrix Balanced Fill-Flash and Center-Weighted Fill-Flash in addition
to standard TTL Automatic Flash Exposure Control and Non-TTL
Automatic Flash Exposure Control. Matrix Balanced Fill-Flash creates
a pleasing, natural effect by filling in harsh shadows and bringing out
subject detail—without losing the correct background exposure.
For details, be sure to read the SB-20 instruction manual and your
camera instruction manual.
Refer to the tables below for usable flash modes in each camera/
SB-20 combination.

Notes:
When using the SB-20’s AF illuminator with AF Nikkor lenses, the
1
focal length is from 24 to 105mm. This range shifts to 15 to 58mm
when using AF Teleconverter TC-16A. The focusing range is approx.
1 to 8 meters (with AF Nikkor 50mm f/1.8 at normal temperatures,
for a standard subject with 35% reflectance).
For bounce flash photography, set the camera's exposure mode to
A or M and select one of the larger apertures.
When the SB-20 is used in Manual Flash Exposure Control, set the
camera’s exposure mode to A or M and manually select lens aperture.

Para los usuarios de las cámaras F4/F4s,
F-801/N8008*
El Speedlight de autoenfoque SB-20 de Nikon le permite efectuar flash
de relleno equilibrado por matriz y flash de relleno equilibrado al
centro además del control de exposición de flash automático TTL
estándar y el control de exposición de flash automático no TTL. El
flash de relleno equilibrado por matriz crea un efecto placentero y
natural llenando las sombras bruscas y resaltando los detalles del
sujeto—y sin perder la correcta exposición del fondo.
Para los detalles, asegúrese de leer el manual de instrucciones del
SB-20 y el manual de instrucciones de su cámara.
Refiérase a las tablas que se indican a continuación para los modos
de flash utilizables en cada combinación de cámara/SB-20.

FOREWORD=
Thank you for purchasing the Nikon Auto
focus Speedlight SB-20. We hope the SB-20
will make photography a much bigger part
of your life. Get to know your SB-20, but
before using it, be sure to read both your
camera instruction manual and this man
ual. Nikon cannot be held responsible for
malfunctions resulting from use of the
SB-20 other than as specified in this man
ual, or from use of the SB-20 with a camera
made by a manufacturer other than Nikon.
---------------
For Nikon F-401/N4004 camera users
Read the following instructions carefully when using the
SB-20 with F-401/N4004 camera.
1. Nikon F-401/N4004 camera is designed for use with
AF Nikkor lenses, except AF-Nikkor 80mm f/2.8,
200mm f/3.5 IF-ED and Autofocus Converter TC-16/
TC-16A.
For most photos in this manual, aperture is set by
rotating the lens aperture ring. With the F-401/N4004,
however, aperture is set using camera’s aperture dial.
Do not forget to set and lock the lens at its smallest
aperture.
For limited use of non-AF Nikkor lenses, see the
F-401/N4004 instruction manual.
2. Most of the explanations in this manual dealing with
Programmed TTL Auto Flash, TTL Auto Flash, etc.,
apply to shooting dark subjects. Flowever, by setting
the F-401/N4004 to program, aperture-priority or
shutter-priority auto exposure mode, with the SB-20
set to TTL, automatic balanced fill-flash is possible in
situations where fill-flash is effective, even with a
bright subject. For details, see the F-401/N4004 in
struction manual. (In manual exposure mode, ordi
nary TTL fill-flash is possible.)

Programmed TTL Auto Flash Shooting (with Nikon F-501/N2020, F-401/N4004 or
F-301/N2000) -----
Steps 9 through 11 provide instructions for program
med TTL auto flash shooting with the Nikon F-501/
N2020*, F-401/N4004** or F-301/N2000* camera.-
For other flash exposure operations (TTL auto, non-TTL
auto and manual flash exposure operations) see “SET
TING CAMERA SHUTTER SPEED” on page 17 and
"DETERMINING APERTURE," pages 18 to 32.
* The Nikon N2020 and N2000 are sold exclusively in the
U.SA. and Canadian markets.
’"'The Nikon N4004 is sold exclusively in the U.S.A. market.
For programmed TTL automatic flash opera
tion, note the following:
• Use Al-S type lenses only. With Nikon F-401/
N4004, use only AF-Nikkor lenses, except
AF-Nikkor 80mm f/2.8, 200mm f/3.5 IF-ED
and Autofocus Converter TC-16/TC-16A.
• For autofocus operation, set the Nikon
F-501/N2020’s focus mode selector to S for
Single Servo Autofocus mode, or set the
Nikon F-401 /N4004 to A for autofocus mode.
For details, see pages 14 to 16.

Q Set the SB-20’s flash mode selector to
TTL.
For the flash shooting range in programmed TTL auto
matic operation, see table on page 21.
The shooting distance range panel at the back of the
SB-20 also helps you to see the flash shooting range.
To read a proper distance range, set the film speed
knob and distance scale selector (see page 19.) A pat
terned bar among the flash shooting distance range
indicators shows the shooting distance range in pro
grammed TTL auto operation.

With the Nikon F-401/N4004, set the camera to either program auto
(aperture dial to S, shutter speed dial to A) or shutter-priority auto (aper
ture dial to S, shutter speed dial to desired speed) exposure mode.
Set lens to minimum
’ aperture (largest
f-number).
With AF Nikkor lenses, lock lens
aperture at minimum setting. (See
the lens instruction manual).
With the Nikon F-401/N4004, this
procedure is unnecessary because
the lens is always locked at the
smallest aperture.

DETERMINING APERTURE
----------------------------------------
TTL Mode
(for TTL Automatic Flash Exposure Control)
TTL mode is for exclusive use with Nikon F-501/N2020, F-401/N4004,
F-301/N2000, FA, FE2, and FG cameras only.
For TTL auto flash operation with the Nikon F-501/N2020, F-401/N4004,
or F-301/N2000, be sure to set the camera to aperture priority auto or
manual exposure mode.
For correct exposure in TTL mode, use film with a film speed specified in
the table below:
