Tips on using the Speedlight  
■Take some trial shots.  
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  
before use.  
Take special care when detaching the SB-27 from your camera.  
For cameras with a safety lock system: loosen  
the mounting foot locking wheel all the way in  
the direction of arrow ■, and slowly detach the  
1
SB-27.  
If the mounting foot locking wheel doesn’t  
loosen easily, do not force it. Push the foot  
forward gently once in the direction of arrow ■  
and try loosening the wheel again.

• 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)].

Installing batteries  
Four penlight batteries (1.5V or lower) of any of the following  
types may be used:  
• AA-type alkaline-manganese (1.5V)  
• AA-type lithium (1.5V)  
• AA-type NiCd (rechargeable) (1.2V)  
• AA-type Ni-MH (Nickel Metal Hydride) (rechargeable) (1.2V)  
Note: High powered manganese batteries are not recommended  
for use with this Speedlight.  
See page 81 for “Notes on batteries.”  
Open the battery chamber lid, and set the camera setting switch.

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.  
Install four penlight batteries and close the battery  
chamber lid.  
2
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.  
12  
Download from Www.Somanuals.com. All Manuals Search And Download.  
■ 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.  
Loosen the SB-27's mounting foot locking wheel.  
1
—A squeaky sound can be heard when loosening the mounting foot  
locking wheel. This is no cause for concern.  
Attach the SB-27 to the camera accessory shoe and  
tighten the locking wheel.  
2
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.)

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.

Setting zoom-head position  
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)  
■Automatic zoom-head positioning is activated.  
■Automatic zoom-head positioning is canceled.

—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 ■.  
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 ■.  
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 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.

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  
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.

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.

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.

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.

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 compensa-  
tion value indicator will not display the sum total of both  
compensation values. Only the compensation value set on the  
SB-27 is displayed.

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 Fill-  
Flash, 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, F90-  
Series/N90, F70-Series/N70 cameras).

hot shoe as the master flash unit, and one or more  
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  
➀Notes 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.  
➀Maintenance  
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.  
➀Storage  
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 (5-  
segment 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 multi-  
sensor 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.

(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-to-  
subject 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.  
(Applicable to F-501/N2020, F-401s/N4004s, F-401/N4004, F-301/N2000)  
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.  
(Applicable to F5, F100, F90X/N90s, F90-Series/N90, F80-Series/N80-Series,  
F70-Series/N70, F65-Series/N65-Series, F-601/N6006, F-601M/ N6000,

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.  
(Applicable to F5, F4-Series, F100, F90X/N90s, F90-Series/N90,
