FOREWORD

Thank you for purchasing the Nikon Autofocus Speedlight
SB-24. Used together with Nikon’s newest SLR models (F4,
F-801/N8008, F-401s/N4004s), it offers you the most advanced
and complete system for automatic flash photography available.
Used with any earlier Nikon SLR model, it lets you take advan
tage of TTL auto control and creative features such as Strobo­effect multiple flash exposures, and more.
To get the maximum performance from your new SB-24, be
sure to take time to read the instruction manual completely. It
includes a great deal of important information, including
explanations on how to use the newest, most advanced
features. Even the most experienced photographers should
thoroughly read this manual. Although the SB-24 controls may
seem familiar, much of its operation is different from ordinary
flash units.
We know you're anxious to get started, so if you are in a real
hurry, read the separate “QUICK AUTOMATIC OPERATION
WITH THE NIKON F4 OR F-801/N8008:' This explains what you
need to know to use the SB-24 and the newest Nikon SLRs in
the most automaitc mode. You'll be surprised how easy that
portion is, and you'll get balanced fill-flash pictures, as easy as
point-and-shoot.

Then, to learn about all the SB-24’s other great features, take
time to read the complete manual. Your reward will be better
flash pictures, with more variety than you ever imagined
possible, and all done easily.
One additional point. Throughout the manual you will see
technical terms or photo expressions with which you may not
be familiar. To help you learn these terms, we've included a
Glossary. So it you come upon an unfamiliar term, check the
glossary on pages 96~97.

The Nikon N8008 and N4004s are sold exclusively in the

U.S.A. The Nikon N2020 and N2000 are sold exclusively
in the U.S.A, and Canada.

NOTES

Do not fire flash near the eyes; doing so may injure the
retina. Do not touch the flash head when firing the SB-24;
it may be hot due to normal operation. Also, be sure to
keep plastics and other delicate materials away from the

flash head when hot.

Nikon cannot be responsible for malfunctions or other
problems resulting from the use of other manufacturers'
flash units, cameras or accessories, including external
power sources.

In certain cases, due to normal characteristics of the built­in microcomputer, the speedlight may not operate or an
abnormal display may appear, even with fresh, properly
installed batteries. If such a case occurs, turn off the flash
and remove the batteries, then reinstall batteries and turn
the power on. This should properly reset the computer.

“Red eye” is a common problem in flash photography.
Normally, flash pictures are taken when the surrounding
light is dim, and under such conditions the subject's eye
pupils will be dilated (open very wide). Red-eye effect
occurs when light from the camera’s flash reflects off the
interior of the eye and back into the camera’s lens. The

wide-open pupil allows much light to enter, and as a result,
the center portions of a subject's eyes can appear bright

red (white in a black and white picture). It is interesting to
note that the intensity of the red-eye effect varies among
individuals, and with two people in the same photograph,

one may have red-eye and the other may not.

The appearance of red-eye is also based on the angle at
which the light flashes on the subject and is reflected back
to the camera's lens. If the angle is 2 to 2.5 degrees or
narrower, the red-eye will occur. As you move closer to a
subject, the angle becomes wider, and the likelihood of
red-eye effect decreases. As you move farther from a
subject, the angle narrows and the incidence of red-eye
increases. When you get very far from a subject, the size
of the eye in the picture may become so small that red-eye
is not apparent, but when you switch to a lens with a
longer focal length, the subject becomes bigger and red
eye may become apparent.
With an angle exceeding 2.5 degrees, red-eye is not likely
to occur. For example, with a 35-55mm range lens and
when standing about 1.4m (4.5 ft) or closer to the subject,
the angle between the flash and lens exceeds 2.5 degrees
and red-eye effect will most likely not be visible.

USABLE FLASH MODES WITH YOUR CAMERA

TTL AUTO an

In this mode, the camera’s TTL flash sensor measures all the

light which passes through the camera’s lens and reflects off
the film surface. This includes both ambient light and light from
the SB-24 flash. The flash shuts off at the moment the sensor
detects the correct exposure. Because the sensor detects light
passing through the lens, it automatically adjusts for most flash
shooting situations, including bounce flash, diffusion filters and
colored or neutral-density filters used on the lens or on the flash
head.
The SB-24's automatic flash operation depends on the Nikon
SLR model used. The chart on the following page indicates the
automatic modes available for each SLR model shown.

The SB-24’s flash mode selector lets you select from four flash
modes—TTL Auto UD , Non-TTL Auto El, Manual BJ or
Repeating-Flash SS . When the power switch Is on, the flash
mode Indicator confirms your selection in the LCD panel.

Subsequent sections of this instruction manual explain each of
the different automatic modes.
Available flash features also vary depending upon the type of
Nikon lens used and camera on which it is used. The newest AF
Nikkor lenses include built-in computers, and used with the
newest Nikon SLR models (F4, F-801/N8008, F-401s/N4004s)—
which incorporate a computer and multi-segment light meter—
provide the most advanced flash operation, known as Matrix
Balanced Fill-Flash.

10

NON-TTL AUTO H

In this mode, light is read through the light sensor on the front
of the SB-24, instead of being measured through the lens.
Exposure control requires that you manually adjust the lens
aperture. For non-TTL auto flash mode, see pages 66 to 68.

MANUAL m

Lets you select flash power from full power of 1/16 power and
set aperture according to flash-to-subject distance. Indicated on
the LCD panel.
For manual flash, see pages 70 to 76.

REPEATING FLASH SIS

This mode lets you flash a subject two or more times
consecutively in the same frame. It enables you to select the
number of flashes, flash speed (FIz) and power—either 1/8 or
1/16.

For detailed instructions on repeating flash, see pages 77 to 80.

FLASH SYNC MODE SELECTOR—

(IIIIIIL)^ )

The SB-24 offers two types of flash synchronization, REAR and
NORMAL.
NORMAL synchronization, the way virtually all other systems
operate, fires the flash at the beginning of the exposure.
REAR synchronization, available with the Nikon F4 or F-801/
N8008, fires the flash at the end of the exposure.
For short exposure (speeds up to 1/250 second) you can barely
tell the difference befween the two methods. For longer expo
sures, however, when subject movement during the exposure
becomes evident, you can clearly see the difference.
Rear synchronization tends to give a more natural effect,
making the blur of subject movement appear to emanate from
the back for a more comfortable visual effect.
For details, see page 48.

READY-LIGHT INDICATIONS

With the SB-24 turned on, its ready-light turns on to indicate the
flash is ready to fire. To activate the viewfinder ready-light
function when using the Nikon F4, F-801/N8008, F-501/N2020,
F-401S/N4004S, F-301/N2000, FA, FE2, or FG, lightly press the
shutter release button to turn on the camera’s meter.

• If the ready-light takes more than 30 sec. to light up
when using alkaline-manganese batteries, replace with
a fresh set.

• With NiCd batteries, if recycling time is over 10
seconds, recharge them.

* •

12

READY-LIGHT WARNING FUNCTIONS

The ready-light in the camera viewfinder blinks in the cases

listed below. When blinking occurs, check the SB-24's flash
mode selector setting, camera's shutter speed/mode selector

setting and/or film speed setting and adjust as necessary.

The ready-light will blink before shooting:

• When SB-24's flash mode selector is at TTL with cameras
other than Nikon F4, F-801/N8008, F-501/N2020,

F-401S/N4004S, F-301/N2000, FA, FE2, or FG. Reset SB-24's

flash mode selector to A or M.

• When using the FA, FE2, or FG to perform TTL auto flash with
the camera’s shutter speed dial at a mechanical setting (M250,

M90 or B). Reset to another shutter speed setting. To use
M250, M90 or B, reset SB-24's flash mode selector to A or M.

• When performing programmed TTL auto or TTL auto flash
operation with a camera film speed setting beyond the usable

range. Use film within the appropriate TTL auto flash photog

raphy range (ISO 25-1000 with F-501/N2020 or F-301/N2000;
ISO 25-400 with F-401S/N4004S, FA, FE2 or FG). With the
FA, the ready-light also blinks when the camera’s film speed

setting approaches ISO 12.

• When the shutter speed of the FE or FM2 is not within the
flash sync speed range. Set the shutter speed to the flash
sync speed or slower.

• With Nikon F-401S/N4004S, when the SB-24 and built-in flash
are turned off, and the camera’s computer recommends flash
use.

After shooting;

With the SB-24 in TTL auto or non-TTL auto flash mode, if both
viewfinder ready-light and SB-24 ready-light blink for a few
seconds after shooting, the flash has operated at maximum
power. Check the SB-24's LCD to determine whether you were
standing at a distance beyond the indicated maximum range.

Depending on conditions, choose a wider aperture for maximum
flash range (switch exposure mode to A or M if it is set at P or
S), or move closer to the subject.

To turn on the speedlight unit, use either STBY (STANDBY) or
ON settings. With Nikon F4, F-801/N8008, F-501/N2020,
F-401S/N4004S, F-301/N2000, FA, FE2, or FG, to conserve
energy, use STBY position,

STBY (STAN DBY) Position
—With Nikon F4, F-801/N8008, F-501/N2020,
F-401S/N4004S, F-301/N2000, FA, FE2, or FG

In most cases, use STBY position to turn on the SB-24. In STBY

position, approx. 80 seconds after the camera's meter turns off,
the SB-24 turns off to conserve power. To turn the SB-24 on
again, lightiy press the camera’s shutter reiease button or the
SB-24's open-flash button.

• When using a remote cord with a Nikon FA or FE2 connected

to Nikon Motor Drive MD-12, the camera remains on as iong
as the MD-12's power switch is on. (At STBY position SB-24
does not turn off.)

Special Standby Function

In normal Standby function, when the camera's meter turns off,
the SB-24 also turns off. To reactivate the SB-24, turn the
camera’s meter on. With the following procedure, however, even
after the camera's meter turns off, the SB-24 automatically

recharges In approx, one-hour Intervals, so it will always be

ready for long shooting sessions.

1. Set power switch to OFF to turn off the SB-24.

2. While pressing illuminator button, set power switch to STBY.

3. Confirm LCD panel display blinks approx. 8 seconds.

• The SB-24 can be kept in standby for approx. 20 days
with AA-type aikaline-manganese batteries or approx.
10 days with AA-type NiCd batteries.

• To cancel this function, set the SB-24's power switch to

OFF.

ON Position
—With Nikon FA, FE2 or FG:

To turn on the SB-24 when using a mechanical shutter setting
(M250 with FA or FE2, M90 with FG, or B), you cannot use
STBY position; set the power switch to ON.

When not using the SB-24, always set power switch to
OFF to conserve battery power.

EXPOSURE COMPENSATION

“Correct” exposure is a value based on combinations of
film sensitivity, aperture and shutter settings necessary to
produce a “technically correct" exposure result. In prac
tical photography, we often want to vary the exposure
results to create different versions of the same picture.

This is accomplished by using exposure compensation.

Exposure compensation can be accomplished in many
ways. The accompanying chart indicates controls that
enable compensation with the Nikon SB-24 and the latest

Nikon SLR models. In addition to changing the exposure,
we can also modify a scene’s lighting by manipuiating

the light source, thus creating different lighting effects.

Exposure compensation

• Automatic compensation

• Automatic compensation + Manual adjustment

Camera side (available-light exposure)

• Manual control

• Automatic control (Matrix Metering)

• Bracketing
[■Manual
^Auto (with optional multi-control back)

The following is a brief explanation of the various
compensation methods, including those accomplished
automatically by the camera/flash computer control,
those accomplished through user-controlled operation
and alternatives which manipulate the lighting on a scene.
As the results can vary depending on individual condi
tions, you may want to experiment with each method.
Experimenting for creativity is what this is all about.

FLASH SIDE COMPENSATION

Computer, automatic: Nikon multi-segment light meters
using advanced computer programs evaluate a scene’s
brightness and contrast and calculate appropriate expo
sure compensation to accommodate a \«ide variety of
complex lighting conditions.

Computer, automatic pius manuai adjustment: auto
matic control as noted above, but with a user-determined
adjustment to the calculated exposure; accomplished
using the SB-24’s EV compensation control.

Manuai adjustment: turn off the camera/SB-24 auto
matic controls and select any manual adjustment using
the SB-24’s EV compensation control.

Rear- or Front-Curtain Sync: not generally referred to
as a compensation method, but can be considered so
because it offers a "different” exposure result.

15

CAMERA SIDE COMPENSATION

Manual control: adjustment made via the camera’s EV
compensation control; affects the entire exposure, both
available light and light from the flash.

For available compensation range with each film speed, see the
table below.

Automatic control: accomplished via the camera's

multi-segment metering system; preprogrammed at the

factory according to extensive testing.

Bracketing: results in a variety of different exposures,
both under- and overexposed; can be accomplished
either by using manual adjustments or by using an
optional multi-control accessory back.

16

LIGHTING MANIPULATION

Bounce flash; can be considered a compensation
method since it offers variation to the exposure and
augments available light; light may be bounced off
various surfaces to create different results.

Multiple flash: using more than one flash to create
specific lighting patterns on the subject. May be used
either

with available light, or to obscure (overpower) the

effects of available light.
Diffusers: devices placed in front of a camera lens to

soften a lighting effect or placed over each flash unit to
modify the quality of the light source.

Indirect flash: removing the flash from the camera and
holding it to the side, above or from below the subject to
create distinctly different lighting effects. This requires a
special extension cord which allows you to maintain
automatic control.

TTL AUTO HD FLASH WITH NIKON F4 OR F-801/N8008-

The SB-24 takes full advantage of the F4 and F-801/N8008's
built-in computer, which automatically synchronizes the
camera's shutter speed and lens aperture to provide precisely
controlled exposures. The capability to handle wider brightness
ranges and use fill-flash under more complex conditions varies
from automatic operation to more advanced user-controlled
options.
With the Nikon F4 or F-801/N8008, by setting the SB-24 to TTL
auto flash mode, you will achieve advanced yet simplified fill­flash photography.

You can choose any of the following flash categories—Matrix
Balanced Fill-Flash, Center-Weighted Fill-Flash or standard TTL
flash, according to the SB-24's TTL mode (with or without auto
matic flash output level compensation) and camera's metering
system (Matrix or Center-Weighted).

FILL-FLASH PHOTOGRAPHY

A backlit subject, such as a person outside with their back
to the sun, or indoors in front of a window, usually appears
as a silhouette if the exposure is set for background
brightness. If the exposure is set for a darker, silhouetted
subject, then the background will be overexposed and
appear washed out.
A better result can be achieved by leaving the exposure
set for the brighter background and then using the flash to
illuminate the darker foreground subject. This brings the
brightness of the foreground subject up to the brightness
of the background. This technique is called "fill-flash", and
fhe SB-24 fogether with a Nikon F4, F-801/N8008 or F-401s/
N4004S provides all the exposure control to automatically
accomplish fill-flash.

Exposure compensated

26

The SB-24 is capable of several different automatic fiii-fiash
methods. The method you choose depends on the Nikon SLR
model you use, lighting conditions, subject movement and the
esthetic quaiities you wish to achieve. Carefully consider each
picture situation.

MATRIX BALANCED FILL-FLASH

This is a feature of Nikon SLR models having muiti-segment
iight meters (Matrix meter). The camera's Matrix meter reads
the scene's iight ieveis and light patterns, and signais the
computer, which then calculates the available-light exposure
settings. When the shutter is released, the camera's TTL sensor
senses available light and flash illumination, then reiays the
information to the computer, which automaticaiiy controls the
flash operation. The computer automatically determines the
appropriate amount of fiash exposure compensation to use.
When the computer senses just the right amount of fiash
iiiumination for a baianced fili-flash exposure (based on the
automatic compensation controi), the flash is turned off. The

result is a well-baianced photo with the correct exposure for
both background and foreground subjects. Ali this takes place
automatically and much quicker than it can be expiained.

standard TTL Flash

27

CENTER-WEIGHTED FILL-FLASH

While the Matrix meter can automatically measure up to five
different segments of the scene's brightness, the Center­Weighted meter measures the entire scene and emphasizes its

reading on the center area. By pointing the center-weighted area
at different parts of the picture, you can choose which bright
ness ievei you want for the basic avaiiabie-light exposure, as
compared to the Matrix system which uses computer evaiuation
to determine the brightness/contrast ieveis upon which exposure
wiii be based.

if the brightness vaiue you have seiected is within the controlied
shutter/aperture range possibie, the fiash output compensation
wiii be automaticaily set for a naturai fiii-fiash effect. The amount
of computer seiected automatic compensation avaiiabie varies
with each Nikon SLR modei. For defaiis, check your camera
instruction manual, if you select a brightness value beyond the
controlled shutter/aperture range, the fiash output will be set
without compensation, as with standard TTL flash operation.

28

STANDARD TTL FLASH

This mode may be used with either the Matrix Meter or Center-1
Weighted Meter. It differs from baianced fiii-fiash operation by

aiiowing you to manuaiiy select the amount of flash compensa- ’
tion instead of having the computer select it automaticaliy. You '
select the amount of compensation, from EV -i-1 to EV -3,

using the SB-24's EV compensation scaie.

Both Matrix and Center-Weighted modes always incorporate
some form of computer compensation, even if you make
adjustments manuaiiy. In Standard TTL mode, only your
manually selected compensation amount is used.

For manual flash outpuf compensation, see pages 46 to

47.

FLASH EXPOSURE COMPENSATION

Varying the amount of flash, in relation to the available-light exposure, creates different
fill-flash effects. We say the fill-flash effect Is balanced when the flash Illumination is
sufficient to brighten the subject to “almost” the brightness of the background. Some
times we want to use a little more or less flash to make the subject a little brighter or
not quite so bright. Your choice may be based on desired esthetic qualities, or may be
forced by extremes in lighting.

Generally speaking, you don't want to make the subject too bright, you just want to
brighten shadows. To achieve a subtle fill-flash effecf, you may wanf to use some
manually selected “minus" compensation. However, when the background is ex
tremely bright, and the subject is in deep shadows, you will probably want to use some

"plus" compensation. While the SB-24 is quite powerful, whenever using it for fill-flash,

it is competing with the sun’s brightness—very strong competition.
With standard TTL flash (with E3 blinking) you can manually compensate exposure by
adjusting flash output level. You can also adjust flash oufput level for Matrix Balanced
Fill-Flash or Center-Weighted Fill-Flash, in combination with the computer’s automatic
compensation.

REAR-CURTAIN SYNC FLASH-For Natural Light Flows

ISea^Inormali

When used with the F4 or F-801/N8008, the SB-24 lets you
synchronize the flash to the instant before the rear (second)
curtain begins to close.
Set the SB-24’s flash sync mode selector to ‘'REAR." This turns

available light into a stream of light that follows the flash-illumi

nated moving subject.
Rear-curtain sync flash photography is most effective with
slower shutter speeds. Although the slowest possible shutter
speed for front-curtain sync flash photography in TTL mode
(with camera at PD, P, PH or A) is only 1/60 second, with rear­curtain sync flash photography, depending on the background,
you can slow the shutter down to 30 seconds.

• In shutter-priority auto or manuat exposure mode, be sure to

seiect an appropriate shutter speed, in programmed auto or
aperture-priority auto exposure mode, confirm shutter speed is
not too stow. Otherwise, it couid affect image sharpness. To
prevent camera shake, use a tripod.

• Rear-curtain sync fiash is avaiiabie when Hash mode selector

is set to TTL, A or M.

TTL AUTO HD FLASH WITH NIKON F-401s/N4004s

SHOOTING BRIGHT AND DARK SUBJECTS

The SB-24’s flash light output control is performed in the same
manner as the camera's built-in TTL flash. The SB-24’s light
output amount, however, is more powerful than the camera’s
built-in TTL flash.
Although the SB-24's shooting distance range is greater than
that of the built-in flash, TTL auto flash shooting operation with
the SB-24 is same as with the camera's built-in flash.

Note that the camera’s viewfinder ready-light LED biinks to
indicate you should use a flash only when the optional flash unit

** attached on the camera is turned off.

• With the F-401S/N4004S camera, for correct exposure
in TTL auto flash mode, use film with a speed of ISO 25
to ISO 400.

• With the F-401 S/N4004S, l£3 mark will not appear.

* •

Depending on the camera’s exposure mode, you can perform
Programmed TTL auto flash or TTL auto flash operation.
Balanced fill-flash is not possible, however, at brightness levels
darker than EV10. The camera’s computer automatically detects
brightness and chooses the appropriate flash mode.

50

Programmed TTL Auto Flash
In Program or Shutter-Priority
Auto Exposure Mode

Programmed TTL auto„flash simplifies
operations, because the camera's i
computer automatically selects both
shutter speed and aperture.

For Programmed TTL auto flash
operation, use only AF Nikkor

lenses, but not AF Nikkor 80mm
f/2.8, 200mm f/3.5 IF-ED or
Autofocus Converter TC-16/TC-16A.

AUTOMATIC BALANCED FILL-FLASH

When the SB-24 is turned off and the scene’s brightness is

EV10 or higher, if the computer's multi-se'gment sensor detects
that the central subject is darker than the surrounding area by
at least 1.5EV, the viewfinder ready-light LED biinks, recom
mending that you should use flash to brighten the picture.
(Note: the SB-24 must be turned off for this signal to operate.
The LED will not blink with the SB-24 In STBY or ON mode.)

Set the camera for Program exposure control and the SB-24 for
TTL exposure control. A balanced fill-flash picture will result,
automatically. It’s that easy.

When using the SB-24 or any other flash In the F-401s/N4004s
hot shoe, bullt-ln speedlight must remain In the down position.
You cannot use both speedlights at the same time. Using the
SB-24 relieves the camera’s power supply from operating the
built-in fiash, and you can expect the camera’s motor to be able
to power more rolls of film.

Using this control you can modify the exposure to make your
picture lighter or darker. To make the picture lighter, use +
compensation. For darker pictures use - compensation. How

much compensation you choose depends on how much you
want to modify the resulting picture.
The shooting distance range for TTL automatic flash operation
varies with the amount of exposure compensation.

For example:

With ISO film, an aperture of fM, and a zoom setting of 35mm, if
you set the camera’s exposure compensation dial at +2, the

flash shooting distance range—which is Im to 9m (approx. 4ft.

NON-TTL AUTO ES FLASH—For Shooting with Varied Lens Apertures

To use various lens apertures for the same subject or when your camera/lens
combination is incompatible with TTL auto flash mode, set the SB-24's flash mode
selector to A for non-TTL auto flash operation.
In non-TTL auto flash shooting, light output varies automatically to match the flash-to­subject distance, but instead of light being measured through the lens, it is measured
by the light sensor on the front of the SB-24.
The SB-24 can be used in non-TTL auto flash mode with any Nikon camera/lens
combination.

68

EXPOSURE COMPENSATION IN NON-TTL AUTO FLASH MODE

The Non-TTL Auto Flash mode works best for subjects of
average (18% gray) reflectance. For very dark subjects, we

recommend closing the aperture about 1/2 to 1 stop smaller
than indicated on the SB-24 LCD. For very bright (almost white)
subjects, it is just the opposite. Open the aperture about 1/2 to

1 stop. Similarly, the automatic system operates best under
average indoor conditions in the home—an average-size room
having white ceilings approx. 2.5 to 3 meter (8 to 10 feet) high.

In a very large room, or in one with very high ceilings, such as
an auditorium, if you are more than about 4.5 to 6 meters (15 to
20 feet) from the subject, you should experiment by opening the
aperture 1 to 2 stops wider than the LCD indicates. Since there
is no way to anticipate any specific condition, you may want to
take a few pictures using exposure bracketing.

SYNCHRONIZATION IN CONTINUOUS SHOOTING

The SB-24 is able to recycle fast enough to synchronize with a
motor-driven camera firing continuously at up to 6 frames per
second at 1/16 light output. This means you can take up to 8
flash pictures in rapid succession.
The maximum number of flashes for continuous shooting are
listed below. Batteries must be fresh to achieve the rates
indicated.

Note: Never fire the flash more than 40 times at 1/8 light
output. After each major flash shooting, let the flash rest at least
10 minutes before firing again.

MANUAL FILL-FLASH

Outdoor fill-flash used with manual mode requires that you
choose the flash-to-daylight ratio that gives the desired effect.
As with automatic fill-flash, your goal is to have the flash
brighten the shadowy areas of the picture, while leaving the
brighter highlights unaffected. To do this you must set up your
shot so the flash exposure will be underexposed by at least one
or two f/stops. The following procedure is just a guideline for
experimentation to enable you to get your desired effect.
