Before taking important flash photographs, take a few trial shots
first to make sure the Speedlight is working properly.
■Use only Nikon-approved equipment.
Your Speedlight has been designed for use in combination with
Nikon cameras, lenses and accessories.
—Using cameras or accessories other than those specified by Nikon
may damage your Speedlight.
—Nikon cannot be held responsible for malfunctions caused by using
the SB-27 in ways not specified in this manual, or using the SB-27 with
a camera made by another manufacturer.
■For further details on camera operation, read the
instruction manual provided with each camera

• LCDs are temperature sensitive, and may turn black at high
temperatures [approx. 40°C (104°F) or above] and become hard to
read.
• In cold temperatures [approx. 5°C (41°F) or below], the LCD's
response time slows down.
These reactions are typical of LCDs and not cause for concern. In both
cases, LCDs will function perfectly again once the temperature returns
to normal [20°C (68°F)].
Preparations for
taking flash photographs
Installing batteries
Four penlight batteries (1.5V or lower) of any of the following
types may be used:
•
•
•
•
AA-type
AA-type
AA-type
AA-type
alkaline-manganese (1.5V)
lithium (1.5V)
NiCd (rechargeable) (1.2V)

Note: High powered manganese batteries are not recommended
for use with this Speedlight.
See page 81 for “Notes on batteries.”
1
Open the battery chamber lid, and set the camera setting switch.
1
2
With cameras in Groups I thru VI, be sure to set the camera
setting switch to K, and set it to ˚ for cameras in Group
VII.
See pages 12, 69 on camera setting switch.
2
Install four penlight batteries and close the battery
chamber lid.
Do not mix battery brands or types, or new and old batteries.
NOTE
Replace the batteries within 30 seconds after turning OFF the
power of the SB-27 to preserve data settings.
Standby function
(Applicable to all camera groups)
When both the SB-27 and the camera are not in use, the
SB-27’s power automatically shuts OFF after approx. 80
seconds in order to conserve battery power. (Standby
function)
Setting the standby function
■ Cameras in Groups I thru VI (featuring TTL Auto Flash)
Set the camera setting switch (inside the SB-27's battery
chamber) to K.
—If it is set to ˚, the standby function will not work.
To turn the SB-27’s power ON again
Lightly press the shutter release button to turn the power ON.
—Pressing the open-flash button also turns the SB-27’s power ON. In this
case, the flash does not fire. (See page 18.)
Standby function will not work when:
• Shutter speed is set at M250 or B (Bulb) (for FA and FE2)
• Shutter speed is set at M90 or B (Bulb) (for FG and Nikonos V).
• Shutter speed is set at B (bulb) (for FM3A).
When your SB-27 is not in use or if you carry it in a bag, we
recommend setting the flash mode selector to OFF to avoid
turning the power ON accidentally.
■ Cameras in Group VII (without TTL Auto Flash)
As the standby function is not available, be sure to set the camera
setting switch (inside the SB-27's battery chamber) to ˚.
NOTE
If you use the SB-27 with two cameras (one featuring TTL Auto Flash
and the other without TTL Auto Flash), we recommend setting the
camera setting switch to ˚ so that the flash mode automatically
switches to t mode with the camera featuring TTL Auto Flash, and
to ˙ mode with the camera without TTL Auto Flash capability.
—Be sure to turn the SB-27's power OFF when the camera setting switch is
set to ˚ as the standby function will not work.
For F50-Series/N50, F-601/N6006, and F-601M/N6000
If camera power shuts OFF with the camera setting switch (inside the
SB-27's battery chamber) set to ˚, the t indicator in the LCD
panel changes to ˙. This is no cause for concern.
If the SB-27's flash mode selector is set to "AUTO", the ˙ indicator in
the LCD panel changes to t enabling TTL Auto Flash operation.
Attaching the SB-27 to the camera
When attaching the SB-27, make sure both the Speedlight
and the camera are turned OFF to avoid accidental firing.
1
Loosen the SB-27's mounting foot locking wheel.
—A squeaky sound can be heard when loosening the mounting foot
locking wheel. This is no cause for concern.
2
Attach the SB-27 to the camera accessory shoe and
tighten the locking wheel.
NOTE
Loosen the mounting foot locking wheel all the way to detach
the SB-27.
With cameras equipped with a safety lock system, the mount pin is
automatically inserted into the locking hole in the camera's
accessory shoe to secure the SB-27. To detach the SB-27, loosen
the mounting foot locking wheel all the way. (See page 9.)
Adjusting the flash head
The flash head rotates from the horizontal to the vertical
position along a 180° arc. From the horizontal position,
simply tilt the flash head up 90° until it clicks into position.
Keep the flash head in the horizontal position for normal flash
shooting.
• When the flash head is set to the left as viewed by the
photographer, a shadow falls to the right of the subject, and if
the flash head is set to the right, the shadow falls to the left.
• When the flash head is set in the vertical position, the shadow
appears under the subject's chin or just behind the subject, as
the flash illuminates the subject from the top.
—This flash-head adjustment capability makes multi-directional bounce
flash operation possible. (See page 49.)
Selecting a measurement system (meters/feet)
Set the flash shooting distance measurement system in the
LCD panel to either meters (m) or feet (ft).
—The system is preset to meters (m) when shipped from the factory.

In AUTO mode, if the ready-light blinks for approx. 3 seconds after
shooting, it means that the flash has fired at its maximum output
but the light may have been insufficient. (See page 40.)
—In that case, reconfirm the flash shooting distance range, aperture and
flash-to-subject distance, and if necessary, use a wider aperture or move
closer to the subject and then reshoot.
Replace batteries with a fresh set.
• Replace alkaline-manganese batteries (or lithium
batteries) if the ready-light takes more than 30 seconds
to light up.
• Recharge NiCd batteries if the ready-light takes more than
10 seconds to light up.

In the horizontal position, the SB-27 has four zoom-head
position settings: 24mm, 28mm, 35mm and 50mm.
Three zoom-head position settings are available in the
vertical position: 35mm, 50mm and 70mm.
—All the above stops are indicated in the LCD panel.
—Zoom-head positioning differs depending on the camera/lens
combination.
Cameras in Groups I and II with Nikkor lenses with built-in CPU
The SB-27 automatically adjusts the zoom-head position to provide
an angle of coverage that matches the focal length of the lens in
use. (Automatic zoom-head positioning)

—When using a Nikkor lens with built-in CPU whose focal length is below
or above the SB-27's available range, the zoom-head automatically
adjusts to the closest focal length setting.
Note: Automatic zoom-head positioning is not possible if a small M
appears above the ZOOM. Press the “ZOOM” button several times
until the M disappears ➀.
NOTE
To cancel automatic zoom-head positioning and set the
position manually:
(1) Press the “ZOOM” and “M” buttons simultaneously for approx. 2
sec. until the small M above the ZOOM starts to blink ➁.
Automatic zoom-head positioning is canceled.
(2) When the small M has stopped blinking, press the “ZOOM”
button and set the desired zoom-head position manually.
When set in this way, the zoom-head position setting remains
unchanged even if the power is turned ON or OFF, or the lens is changed.
• To resume automatic zoom-head positioning, perform procedure (1)
above to make the small M above the ZOOM disappear. If the small M
is still visible, continue to press the “ZOOM” button.

Guide numbers for determining correct aperture
The “guide number” represents the amount of light
generated by the flash. With the SB-27 in Manual (M) Flash
mode, you can calculate a correct aperture (f/stop) value by
using the following equation and the “Guide number” table.
—For Guide numbers in 1/300 TTL High-Speed Sync Flash
operation with the F5 camera, see page 40.

Autofocus flash operation in dim light
(For AF SLR cameras only)
Nikon AF SLR cameras using AF Nikkor lenses can
autofocus in light as dim as a single candle. When ambient
light is insufficient for autofocus operation, the
SB-27's AF assist illuminator LED automatically turns ON to
give contrast to dark subjects, enabling the camera's
autofocus system to function when the shutter release
button is pressed halfway.
Take care not to block the AF assist illuminator LED.
—The AF assist illuminator LED goes out as soon as the subject has been
correctly focused.
• No AF assist illuminator LED lights up if the F5’s, F100’s, F80-Series/
N80-Series’ or F65-Series/N65-Series’ central focus area is not selected.
Be sure to select the central focus area.
Autofocus flash operation in dim light
(For AF SLR camera only)
Conditions for autofocus flash operation with the
AF assist illuminator LED
1) The subject must be sufficiently dark to activate the autofocus
assist illuminator LED.
Please note that AF assisted autofocus range extends from
1m (3.3 ft.) to 5m (16.4 ft.) at 20˚C (68˚F).
2) AF Nikkor lenses must be used.
Using AF Nikkor lenses, SB-27's focal length coverage ranges
from 24mm (35mm for F-501/N2020) to 105 mm.
Other AF Nikkor lenses may also be used depending on shooting
conditions. Be sure to take a few trial shots first.
3) The camera's autofocus mode should normally be set to Single
Servo AF (S).
4) Focus lock is not in use.
5) The ready-light is ON.
If the ready-light becomes dim or blinks after the AF assist
illuminator LED lights up, replace the SB-27's batteries with a
fresh set.
*If the AF assist illuminator LED comes ON but no in-focus indicator
appears in the camera's viewfinder with the shutter release button pressed
halfway, the subject is beyond autofocus distance range. Set the focus
mode to "Manual" and focus manually on the clear matte field.
Bounce flash operation
(For cameras in all groups)
Normal flash shooting using
direct flash
Bounce flash shooting using
diffused light
Direct flash causes harsh, unattractive shadows to appear
on the faces of subjects in front of a wall. By bouncing the
light off the ceiling or walls, you can soften the shadows and
produce more natural portraits.
Vertically bounced light
The flash head rotates from the horizontal to the vertical position
along a 180° arc.
Built-in diffuser card
The SB-27 comes with a built-in diffuser card, useful for
highlighting a subject's eyes during bounce flash operation.
(See page 53.)
Bounce flash operation (Applicable to all camera groups)
Notes on taking pictures with vertical bounce flash
The settings of the built-in bounce flash adapter and the diffuser
card vary depending on the focal length of the lens in use.
Nikkor lenses 35mm and longer
Set the built-in bounce flash adapter as shown.
—When set as above, you cannot use Nikkor lenses wider than 35mm.
(See the illustration [center] on the seal affixed to the bounce flash
adapter.)
Also set the diffuser card when you want to create a "catchlight" to
highlight the subject's eyes. (See page 53.)
Nikkor lenses 24mm and longer
Set both the built-in bounce flash adapter and diffuser card as shown.
—Even when set as above, you cannot use Nikkor lenses wider than
24mm. (See the illustration [bottom] on the seal affixed to the bounce
flash adapter.)
Always set the diffuser card whether you wish to create a
"catchlight" or not. (See page 53.)
Notes on taking pictures with flash in vertical position
• With the built-in bounce flash adapter mounted, use Nikkor
lenses 50mm or longer.
• With both the built-in bounce flash adapter and the diffuser card
mounted, use Nikkor lenses 35mm or longer.
Procedures for bounce flash operation
1
Set the camera's exposure mode to aperture-priority
auto (A) or manual (M).
With bounce flash operation, there is 2 to 3 f/stops less light
available than in normal flash operation. We recommend that
you select wider aperture (lowest possible f-number) and
bracket to ensure correct exposure.

3
Check the reflective surface and adjust flash head direction.
NOTE
Choose a reflective surface with a high reflection factor such
as a white wall for bouncing the light off.
In color photography, only use bounce against white reflective
surfaces. Otherwise, color photographs will come out with an
unnatural color cast similar to that of the reflective surface.

and then reshoot.
—In bounce flash operation, no indicator bars appear in the LCD
panel. (The SB-27 no longer indicates the correct relationship
between aperture and flash shooting distance range.)
Highlight your subject’s eyes using bounced flash
The SB-27 comes with a built-in bounce flash adapter for bouncing
diffused light off the ceiling. The diffuser card brightens shadows
caused by top-lighting or bouncing flash, making your subject’s
eyes appear more vibrant.
To set up the diffuser card:
1
Set the built-in bounce flash adapter.
2
Unfold the built-in diffuser card.
Close-up flash operation in AUTO mode
(Cameras in Groups I thru VI)
The SB-27 incorporates a built-in diffuser card which
diffuses light, enabling you to take close-up flash pictures
from 0.3m (1 ft.), softening harsh shadows and producing
natural-looking results with the SB-27 mounted on the
camera.
Two methods are possible:
(1) Mounting the SB-27 on the camera (See page 56.)
(2) Connecting the SB-27 to the camera using an optional TTL
Remote Cord (See page 59.)
—With a very light or dark-toned subject, you may not get a correct
exposure due to the subject's reflection factor. See page 60 on
"Exposure compensation for flash photography" and page 69 on
"Setting Forced TTL and Forced A modes" to ensure correct exposure.
Notes on close-up flash operation
Take note of the following points when shooting close-ups with the
SB-27 mounted on the camera.
Usable lenses are limited.
Avoid using any Nikkor lens whose actual length is shorter than
that of the built-in bounce flash adapter (
line in the illustration).
If the lens is too short, the incident light falling on the lens reflects
on the built-in bounce flash adapter causing a flare effect on the
film. (See the illustration [top] on the seal affixed to the bounce
flash adapter.
Other notes
In close-up flash operation, we recommend taking trial shots first
because pictures may be slightly dim or a shadow may appear
around the edge of the frame depending on the lens in use or the
flash-to-subject distance.

* An aperture of f/8 is suggested. We recommend using the smallest
possible aperture ( f/11 or f/16).
With a very light or dark-toned subject, you may not obtain a
correct exposure due to the subject's reflection factor. Use
exposure compensation to ensure correct exposure.
(See pages 60, 69.)
5
Confirm that the ready-light is ON, then release the
shutter to fire the flash.
Exposure compensation for flash photography
"Plus" compensation
"Minus" compensation
In AUTO (TTL Auto Flash) mode, difficult scenes, such as
bright objects in the background, or a main subject at the
edge of the frame, may cause overexposure or
underexposure. You can manually adjust the exposure
(compensate the Speedlight's light output level in TTL Auto
Flash mode) to make the picture lighter or darker.
When the background is extremely bright, use “+”
compensation and when the background is very dark, use
“–” compensation.
—In Automatic Balanced Fill-Flash with TTL Multi Sensor operation using
cameras in Group I, the camera automatically compensates exposure
according to the shooting conditions. Flash light output level
compensation is not necessary inside the normal flash shooting distance
range.
—Make sure that the flash shooting distance range shifts when the
exposure is compensated. Check that the subject is within flash shooting
distance range after compensation.
(Cameras in Groups I thru III)
Setting exposure compensation for flash
The setting method varies depending on the camera.
Cameras in Groups I and II
Cameras with EV compensation control capability allow you to
compensate flash exposure on either the SB-27 or the camera (or
both.) If you use both controls, exposure is modified by the sum
total of both exposure compensation values.
For example, with a compensation of +1EV on the SB-27 and +1EV
on the camera, the background will be +1EV and the flash output
will be +2EV. Keep in mind that the SB-27's exposure compensation value indicator will not display the sum total of both
compensation values. Only the compensation value set on the
SB-27 is displayed.

With Group III cameras, the SB-27's LCD panel does not show the
correct flash shooting distance range or the correct compensation
amount. Use the following chart as a guide for obtaining the
correct flash shooting distance range.
For example, with ISO 100 film, if you want to compensate by +1EV
on the camera, set the ISO film speed to 50 on the SB-27’s LCD
panel; if you want to compensate by –2EV, set the ISO film speed
to 400.
NOTE
With exposure compensation set on the camera, the SB-27’s light
output is automatically controlled for correct background
illumination.
Multiple flash operation—using more than one Speedlight
(Applicable to all camera groups)
Flash shooting with one flash unit
Flash shooting with more than one unit
When you wish to eliminate harsh shadows produced by a
single flash unit or if you want to extend light up into the
background, use more than one flash unit.
For multiple flash operation with the SB-27, both TTL Auto
and Manual (M) Flash modes are available.
—Multiple flash operation in TTL Auto Flash mode is possible with cameras
in Groups I thru VI and F3-Series cameras. Multiple flash operation in
Manual (M) Flash mode is possible with cameras in all groups.
—In multiple flash operation in either TTL or manual mode, first decide
which will be the main (Master) unit and which the secondary (Slave)
unit(s). For example, to eliminate shadows, adjust the lighting ratio so
that master unit illumination is greater than secondary unit illumination.
NOTE
Cameras in Group I
With the SB-27 as the master flash set to 3D Multi-Sensor Balanced FillFlash, you may not be able to obtain correct exposure because of a
change in lighting conditions between initial Monitor Preflash* and actual
flash firings. First cancel Monitor Preflash using one of the following
methods:
• Set the built-in wide flash adapter to the upper or left direction.
• Set the SB-27's flash operation to Standard TTL Flash (not Matrix
Balanced Fill-Flash.)
• Mount a Nikkor lens without built-in CPU.
• Set the camera's metering system to Spot (except F90X/N90s, F90Series/N90, F70-Series/N70 cameras).
*See page 86 on Monitor Preflash.

• In multiple flash operation, if the electric current in the synchro
circuit exceeds a certain level, you may not be able to take a
second shot after the first. In this case, turn each of the flash
units OFF once or disconnect the master flash unit from the
camera. This resets the circuits so you can resume shooting.
• In multiple flash operation, take care that the combined total of

Speedlights mounted on the Wireless Slave Flash Controller
SU-4s as slave flash units. The SU-4’s built-in light sensor not
only detects when the master flash unit fires to trigger the
slave flash unit, but also controls the flash duration of the
slave flash unit in sync with the master flash unit.
Manual multiple flash operation is also possible by setting the

Tips on Speedlight care
■Avoid physical shocks
Do not drop or hit the SB-27 against a hard surface.
—This may damage the precision mechanism.
■Never disassemble
Never disassemble or repair the SB-27 when it is damaged or
malfunctioning.
—The SB-27 houses high-voltage circuitry which is highly dangerous.
■Keep the SB-27 away from water
Do not expose the SB-27 to rain or water as it is not waterproof.
—If water gets inside the SB-27, the internal parts may corrode, resulting
in high repair costs if repair is at all possible.
Tips on Speedlight care
■Notes on cleaning
Use a blower brush to remove dirt and dust from the SB-27 and
clean lightly with a soft, clean cloth .
—Do not use commercial cleaners containing active agents such as paint
thinner or benzene.
■Maintenance
When not using the SB-27 for prolonged period of time (more than
two weeks), be sure to remove the batteries before storage. Take
the SB-27 out about once a month, insert the batteries and fire the
unit several times to prevent the condenser from deteriorating.
Finally make sure the ready-light is on, before turning the power
off and removing the batteries.
■Storage
Store the SB-27 in a cool, dry place to prevent mold. Also keep it
away from chemicals such as camphor or naphthalene. Avoid
exposing the SB-27 to magnetic waves (TV or radio) and high
temperatures (e.g. car interiors or heaters.)
Notes on batteries
Battery power tends to weaken as the temperature drops; it
also drains off slowly when not in use for a long period of
time, and recovers after a short break following intensive
use. Be sure to replace the batteries with a fresh set if you
notice any delays in recycling.
• Do not mix battery brands or types, as battery performance
differs with each brand.
• When installing the battery, turn the SB-27's power OFF and
make sure that the battery terminals +≠ are correctly oriented.
• When replacing batteries, be sure to replace all the batteries at
the same time. Always use fresh batteries of the same brand and
type.
—Wrong battery usage may shorten battery life or cause malfunction.
• Do not disassemble, short-circuit or heat batteries. Do not
dispose of batteries by burning, as explosions may result.
• If the SB-27 is not in use for more than two weeks, remove the
batteries from the flash unit and keep them in a cool, dry place
below 20°C (68°F).
Warning:
• Batteries shall not be exposed to excessive heat such as
sunshine, fire or the like.
• Dry batteries shall not be subjected to charging.
Notes on batteries
About NiCd batteries
Please note the following points when using NiCd batteries.
• NiCd batteries feature a faster recycling time and greater
efficiency at low temperatures than alkaline-manganese
batteries.
—Other performance data differs depending on battery conditions, and
whether or not batteries are fresh or fully charged.
• When charging NiCd batteries, be sure to use the battery
charger specified by the battery maker and read the instruction
manual thoroughly.
• Charging should be made in an ambient temperature ranging
from 10°C to 30°C (50°F to 86°F).
• Do not recharge NiCd batteries with the reverse terminals
connected or before the batteries have cooled off.
• Overcharging and excessive use may shorten battery life. Do not
overcharge and be sure to turn the power OFF when not using
your Speedlight.
• If NiCd batteries do not last as long as they should after being
properly charged, they are approaching the end of their life.
Replace them with new ones.
Using the SB-27 in low temperatures
As the temperature drops, battery performance becomes
degraded. When taking photographs in low temperatures, use
fresh batteries, and keep a set of spares in a warm place (e.g. a
coat pocket), or use fully-charged NiCd batteries. The SB-27 will
not fire if weak batteries are used in low temperatures.
—Battery power will recover when the temperature goes back to normal.
Avoid warming or cooling the batteries too quickly as this may cause
battery voltage to become unstable.

1/300 TTL High-Speed Sync Flash
The F5’s sync shutter speed can be set to 1/300 sec. using a custom function
setting. This is available with the SB-27 set to AUTO (TTL) and the camera’s
exposure mode set to S or M. In this case the SB-27’s guide number is approx.
14 (at the 35mm zoom-head position, ISO 100: for m).
In P or A mode, 1/300 TTL High-Speed Sync Flash does not work and shutter
speed is automatically set to 1/250 sec.
(Applicable to F5)
3D Multi-Sensor Balanced Fill-Flash
This mode automatically controls flash output so as to keep both subject and
background perfectly exposed.
The SB-27 fires a series of nearly invisible preflashes or
Monitor Preflash. These preflashes are detected by the TTL multi-sensor (5segment sensor) in Group I cameras and the data is then integrated with
distance information from D-type Nikkor lenses and other exposure data to
determine the optimal flash shooting distance range and light output level for
balanced fill-flash exposure. This is especially effective with scenes that
include: (1) a mirror, white wall or other highly reflective surface, (2) unwanted
obstacle(s) in front of the subject.
(Applicable to F5, F100, F90X/N90s, F90-Series/N90, F80-Series/N80-Series,
F70-Series/N70)
Autofocus assist illumination
Allows you to autofocus in dim light or in the dark with Nikon AF cameras.
When you press the shutter release button halfway, the AF illuminator
automatically turns ON to give contrast to a dark subject, thus enabling the
camera’s autofocus system to function.
(Applicable to all Nikon AF cameras)
Automatic Balanced Fill-Flash with TTL Multi Sensor (3D multisensor balanced fill-flash and multi-sensor balanced fill-flash)
With D-type AF Nikkor lenses, 3D multi-sensor balanced fill-flash is performed,
whereby the SB-27 fires a series of weak preflashes (Monitor Preflash) that are
detected by the camera’s TTL Multi Sensor, then analyzed for brightness and
contrast along with Distance Information from the D-type AF Nikkor lens. The
flash output level is automatically compensated so that both flash output and
ambient light are perfectly balanced.
With non-D-type AF Nikkor lenses, Multi-Sensor balanced Fill-Flash, which offers
the same output control system minus Distance Information, is performed.
These flash modes are effective in scenes with highly reflective objects such
as a mirror or a white wall, and scenes with very dark backgrounds.
(Applicable to F5, F100, F90X/N90s, F90-Series/N90, F80-Series/N80-Series,
F70-Series/N70)
Bounce flash operation
Bounce the light off the ceiling or walls to illuminate the subject
indirectly, softening shadows and producing more natural portraits.
The SB-27 comes with a built-in wide flash adapter for this purpose.
(Applicable to all camera groups)
Catchlight
By using the SB-27’s built-in diffuser and bouncing the light off the
ceiling, you can create a “catchlight” which softens harsh shadows
caused by bounced light, resulting in more natural portraits.
(Applicable to all camera groups)
Center-Weighted/Spot Fill-Flash
This mode operates with Center-Weighted or Spot metering. These
metering systems measure the background brightness and control
the flash, providing less light than with Matrix Balanced Fill-Flash.
Recommended with non-AF Nikkor lenses in place of Matrix
Balance Fill-Flash, which cannot be used.
(Applicable to F5, F4-Series, F100, F90X/N90s, F90-Series/N90,
F70-Series/N70, F60-Series/N60, F50-Series/N50, F-801s/N8008s,
F-801/N8008, F-601/N6006, F-601M/ N6000, F-401x/ N5005)
Flash exposure compensation
In combination with on-camera exposure compensation, you can
manually adjust the amount of flash output when using a Speedlight
in AUTO flash mode. To achieve correct exposure with a large
white background, a small subject in the center of the viewfinder, or
a subject close to the edge of the frame, underexpose; overexpose
if your subject is positioned against an “infinity” background.
(Applicable to all camera groups except group VII)
Flash shooting distance range
Your subject must be within acceptable flash shooting distance
range in order to receive sufficient illumination from the flash. This
range varies depending on the aperture and ISO film speed. In
flash operation, make sure that the subject is within flash shooting
distance range.
(Applicable to all camera groups)
Glossary of terms
Front-curtain sync flash
In normal flash synchronization, the Speedlight fires at the
beginning of the exposure. The flash therefore fires just after the
front-curtain opens. Rear-curtain sync flash is also possible with
cameras featuring a rear-curtain flash sync mode set on the camera.
(Applicable to all camera groups)
Guide Number
This number refers to the maximum light output in units of GN [ISO
100 . m(ft)]. A guide number is given to help determine the correct
aperture or f/stop value, or flash shooting distance using the
following equation.
guide number
flash-to-subject distance (m)
guide number
flash-to-subject distance (m)=
f/stop (aperture)
f/stop (aperture) =
(Applicable to all camera groups)
Matrix Balanced Fill Flash
This mode automatically controls flash output so as to keep both
subject and background perfectly exposed.
The camera's Matrix Metering System determines the correct
exposure based on ambient light. Flash illumination brightens the
main foreground subject but does not overpower the background.
(Applicable to F4-Series, F-801s/N8008s, F-801/N8008, Pronea 600i/6i,
F-601/N6006, F-601M/N6000, F65-Series/N65-Series, F60-Series/N60,
F50-Series/N50, and F-401X/N5005)
Monitor Preflash
In Automatic Balanced Fill-Flash with TTL Multi Sensor mode,
immediately after you depress the shutter release button and
before the shutter is activated, the SB-27 fires a brief series of
nearly invisible preflashes known as Monitor Preflash. These
preflashes are detected by the camera's TTL Multi Sensor, then
analyzed for brightness and contrast ensuring optimal exposure.
(Applicable to F5, F100, F90X/N90s, F90-Series/N90, F80-Series/N80-Series,
F70-Series/N70)
Multi-Sensor Balanced Fill-flash
This mode automatically controls flash output so as to keep both
subject and background perfectly exposed.
The SB-27 fires a series of nearly invisible preflashes or Monitor
Preflash, which are detected by the TTL multi-sensor (5-segment
sensor) in Group I cameras to help determine the best exposure
for both subject and background. This method is most effective in
scenes that include: (1) a mirror, white wall or other highly
reflective surface, and (2) a subject positioned against an “infinity”
background (empty sky, clouds, etc.) With non-D-type AF Nikkor
lenses, Multi-Sensor Balanced Fill-Flash will operate.
(Applicable to F5, F100, F90X/N90s, F90-Series/N90, F80-Series/N80-Series,
F70-Series/N70)
Multiple flash operation
Flash operation using more than one speedlight to eliminate harsh
shadows or to illuminate a distant background.
(Applicable to all camera groups)
Non-TTL auto flash
The light output is automatically controlled to match the flash-tosubject distance measured by the Speedlight’s light sensor.
(Applicable to all camera groups)
Programmed TTL Auto Flash
Simply set the lens to its minimum aperture (highest f-number),
and the camera automatically controls the aperture according to
the ISO film speed.

Rear-curtain sync flash
In this case, the flash fires at a later stage of the exposure, just
before the rear shutter curtain starts to close. This is effective for
highlighting subject movement at a slow shutter speed. This
method turns available light into a stream of light that follows the
flash-illuminated moving subject. In front-curtain sync flash,
available light turns into a stream of unnatural light that appears
before the flash-illuminated moving subject.

Glossary of terms
Red-eye reduction
The SB-27's red-eye reduction lamp lights up for approx. 1 sec.
before the flash fires. This prevents eyes from appearing red in
color pictures or white in B/W pictures, a phenomenon known as
“red-eye” effect.
(Applicable to F100, F90X/N90s, F90-Series/N90, F80-Series/N80-Series,
F70-Series/N70, F65-Series/N65-Series, Pronea 600i/6i cameras)
Standard TTL Flash
You can manually select a flash output level so that the main
subject is correctly exposed regardless of the background
brightness. Otherwise the main subject may appear unduly
emphasized against the background.

F-301/ N2000, Pronea 600i/6i, FM3A, FA, FE2, FG, and Nikonos V)
Sync shutter speed
This refers to the highest available shutter speed for flash
synchronization; although slower speeds can be used, higher
speeds cannot.
