* 1 The aperture where overexposed pictures may result in TTL auto flash operation if a larger
aperture (smaller f-number) than that is used.
•For example, when shooting a subject at a distance of 0.25m (0.82 ft.) using
ISO 100 film, the correct aperture is:
f/stop = 2 (coefficient) / 0.25 (m) (flash-to-subject distance) = 8
f/stop = 6.6 (coefficient) / 0.82 (ft) (flash-to-subject distance) = approx. 8
From the above equation, use an aperture smaller than the f/8 (larger f-number) in the TTL mode.
TTL Auto Flash Mode TTL
In this mode, the built-in TTL auto flash sensor in cameras so equipped
measures the SB-29’s illumination that is reflected back from the subject
based on the aperture set on the lens and automatically controls the flash
output to ensure proper exposure. This mode provides simple and effective
flash operation for close-up flash photography.
Note
In close-up flash photography where exposures are often affected by the ambient
light, it’s a good idea to take additional shots at various exposure settings. (Refer to
“Exposure compensation in close-up flash photography.”)
Set the flash mode selector on the SB-29 to TTL. 1
Set your camera correctly. (Refer to your camera’s instruction manual for details.)
•Set your camera’s exposure mode to Aperture-priority auto A or Manual M mode.
Programmed auto P (aperture not selectable) and Shutter-priority auto S modes
are not recommended, because choosing an appropriate shooting distance
range to match the reproduction ratio is difficult.
•Set your camera’s metering system to Matrix Metering, Center-Weighted
Metering or Spot Metering.
•The shutter speed is automatically set to the flash sync speed. (Or you can
intentionally set the shutter speed to one slower than the flash sync speed.)
•Because the SB-29 features the same TTL flash operations as the SB-22 or
SB-22s, refer to them in the flash photography section of your camera’s
instruction manual, if the SB-29 is not listed.
Set the aperture on the lens or camera.
•Determine an appropriate aperture by referring to the “Aperture/reproduction
ratio panel” on the back of the SB-29 controller. (Refer to “Determining a proper
flash shooting distance range.”)
Wait for the SB-29’s ready-light to come on before taking the picture.
•You can also use the ready-light in the viewfinder of your camera.
•If the ready-light on the SB-29 or in the viewfinder blinks for approx. 3 seconds
after shooting, this indicates the light may have been insufficient for correct
exposure. In this case, use a wider aperture (smaller f-number) and reshoot.
•If the SB-29’s overexposure warning indicator LED lights up for approx.
4 seconds after shooting, this indicates the picture may have been overexposed.
In this case, use a smaller aperture (larger f-number) and reshoot.

■ Determining a proper flash shooting distance range
Using the “Aperture/reproduction ratio panel” (with the lens in normal position)
Use the “Aperture/reproduction ratio panel” on the back of the SB-29 controller to
determine usable apertures at the desired reproduction ratio. The proper apertures
depend on the ISO film speed, lens focal length and the desired reproduction ratio.
Note
The figures on the panel are effective f-numbers. They are not apertures on the lens.
(See “Aperture to set on the lens and effective f-number”.
•The settings and scales on the Aperture/reproduction ratio panel are for use with AF Micro-
Nikkors 60mm f/2.8D, 105mm f/2.8D, and 200mm f/4D IF-ED.
If you use the AF Zoom Micro-Nikkor 70-180mm f/4.5-5.6D ED, determine the appropriate
figures on the panel depending on a focal length set on the lens. Apply this to other lenses.
•For example, at a 1:5 reproduction ratio with ISO 100 film and the AF Micro-Nikkor 60mm lens,
the usable apertures are from f/4 to f/32.
When an over- or underexposure warning indication appears (with the lens
in reverse position, or when the reproduction ratio is greater than life-size.)
In the above case, the correct exposure cannot be obtained using the “Aperture/
reproduction ratio panel.” Determine the usable aperture by referring to the following
“Maximum aperture.” If the overexposure warning indication appears, use a smaller
aperture (larger f-number) or if the underexposure warning indication appears, use a
larger aperture (smaller f-number) and reshoot.
f/stop (maximum aperture* 1 ) = Coefficient / flash-to-subject distance (m/ft)
ISO film speed

Checking the lighting effects before shooting
■ Modeling illuminator
Using the modeling illuminator, you can check how the subject will be
illuminated and see how the shadows will look before actually taking pictures.
Set the SB-29 and your camera, then focus on the subject.
Wait for the ready-light to come on before pressing the modeling
illuminator button as you look through the viewfinder. 2
1
•The modeling illuminator will not light up unless the ready-light is on.
•While the modeling illuminator button is pressed, the modeling illuminator lights up—for a
maximum of approx. 3 seconds (when both modules are fired), if the flash is completely
recycled. Of course, the duration varies if the flash is not completely recycled.
Manual Flash Mode M
Use Manual Flash M mode, if your camera does not feature TTL auto flash
operation. Flash output levels of M and M1/4 can be selected.
M: Flash fires at full output.
M1/4: Flash fires at 1/4 of the full output.
•To obtain the correct exposure at a reproduction ratio of less than 1:10, determine the
aperture using the SB-29’s guide number and the shooting distance.
•At a reproduction ratio of 1:10 or greater, it is difficult to obtain the correct exposure
because the aperture and the effective f-number may differ.
Note
In close-up flash photography where exposures are often affected by the ambient
light, it’s a good idea to take additional shots at various aperture settings. (Refer to
“Exposure compensation in close-up flash photography.”)
Set the flash mode selector to M1/4 or M.
Adjust your camera.
•Set your camera’s exposure mode to Aperture-priority auto A or Manual M .
•Set your camera’s metering system to any setting.
•The shutter speed is automatically set to the flash sync speed, except Nikon
New FM2 and FM10 cameras. Or you can intentionally set the shutter speed to
one slower than the flash sync speed. For Nikon New FM2 and FM10 cameras,
manually set the shutter speed to the flash sync shutter speed or slower.
Set the appropriate aperture on the camera or lens aperture ring.
•At a reproduction ratio of less than 1:10, use this equation to determine the
correct aperture:
f/stop (aperture) = guide number / flash-to-subject distance (m)
At a reproduction ratio of 1:10 or greater, the above equation is not
recommended as it is difficult to obtain the correct aperture.
•With Micro-Nikkor lenses mounted on the camera, refer to the “Aperture/
reproduction ratio panel.”
For example, when shooting with an AF Micro-Nikkor 60mm f/2.8D lens using
ISO 100 film, determine an appropriate aperture by referring to the “Aperture/
reproduction ratio panel.”
At a 1:5 reproduction ratio, the effective f-numbers for the correct exposure
are f/32 at Manual (full) and f/16 at Manual (M1/4) flash output.
•When a Nikkor lens with a built-in CPU is mounted on the camera and when you
set the aperture in the camera’s viewfinder or on the LCD panel, the aperture
value appearing on the LCD panel or in camera’s viewfinder is the effective
f-number. Set this value on the camera.
•When a Nikkor lens without a built-in CPU is mounted or no aperture value is
displayed in the viewfinder, calculate the effective f-number using the aperture
set on the lens according to the reproduction ratio, then determine an
appropriate aperture by referring to the “Aperture/ reproduction ratio panel.”
For example:
At a 1:10 reproduction ratio, the effective f-number is approx. 1/3 of an f/stop
smaller than the aperture set on the lens.
At a 1:5 reproduction ratio, the effective f-number is approx. 1/2 of an f/stop
smaller than the aperture set on the lens.
At a 1:3 reproduction ratio, the effective f-number is approx. 2/3 to 1 f/stop
smaller than the aperture set on the lens.
At a 1:1 reproduction ratio, the effective f-number is approx. 2 f/stops smaller
than the aperture set on the lens.
Wait for the SB-29’s ready-light to come on before taking the picture. 4

Reproduction ratios and the “Aperture/reproduction ratio panel”
■ Determining the reproduction ratio
For Micro-Nikkor lenses in normal position, read the number engraved on the
lens focus ring. It is usually in the form of 1:n or 1/n. When using Nikon
Bellows Focusing Attachment, refer to its instruction manual.
For other lenses, follow these procedures to determine the reproduction ratio:
Place a ruler in the same plane as the subject, then read the subject’s
length as seen in the viewfinder. 1
Calculate the reproduction ratio by using this equation:
M = 36 / L
where M = Reproduction ratio
36 = Length of the long side of the viewfinder frame (varies depending
on camera in use)
L = Length of the subject as seen in the viewfinder
•The viewfinder frame size is 24 x 36mm for cameras having 100% frame
coverage and 21 x 32mm for cameras with 90% frame coverage.
•In the above example, the viewfinder frame size is 24 x 36mm. Since the
subject appears as approx. 21mm along the long side of the viewfinder frame,
the reproduction ratio (M) is:
M = 36 / 21 = approx. 1.7x.
If you measure the length of the subject by placing a ruler along the short side of
the viewfinder frame, use this equation:
M = 24 / L
Or if the viewfinder frame size is 21 x 32mm, the reproduction ratio (M)
is 32/21 = approx. 1.5x. Likewise, if you measure the subject by placing the ruler
on the short side of the viewfinder frame, the reproduction ratio is determined by
the equation
M = 21 / L.
■ Aperture to set on the lens and effective f-number
Effective f-numbers of macro lenses such as Micro-Nikkor lenses vary and the
brightness of images on the film decrease when the reproduction ratio increases. The
relationship between the reproduction ratio and the effective f-number is:
Fe = F (1 + M)
where Fe = Effective f-number (actual lens speed)
F = Aperture to set on the lens
M = Reproduction ratio
•For example, to obtain a 1:1 (life-size) reproduction ratio at an aperture of f/8 set on
the lens, Fe = 8 (1 + 1) = 16. The effective f-number is 16 which is two stops darker.
Effective f-numbers are displayed on the SB-29’s “Aperture/reproduction ratio panel.”
To obtain the correct exposure in TTL auto flash operation, proceed as follows:
•The aperture value appearing on the LCD panel or in camera’s viewfinder is the
effective f-number when a Nikkor lens with a built-in CPU is mounted on the camera.
•When a Nikkor lens without a built-in CPU is mounted or no aperture value is
displayed in the viewfinder calculate the effective f-number using the above equation
after setting the aperture on the lens.

Exposure compensation in close-up flash photography
In close-up flash photography, it’s recommended to take additional shots with
varying exposures to ensure getting the correct exposure.
Exposure compensation in TTL Auto Flash “TTL” mode
•Make exposure compensation on the camera to match the shooting situation. Refer to
your camera’s instruction manual for details on how to make exposure compensation.
•When shooting a subject containing highly reflective surfaces, use some plus
compensation. When the background is very dark, or the subject is in deep shadow,
use some minus compensation.
•Normally you can compensate exposures within a range of –2 EV to +1 EV.
•When minus compensation is made, the overexposure warning indicator LED may
light up. In this case, set a smaller aperture (larger f-number) on the lens, then make
minus compensation again.
Exposure compensation in Manual “M” mode
•Intentionally change the aperture set on the camera or lens aperture ring.
•When you want an overexposed picture, set a wider aperture (smaller f-number). For
an underexposed picture, use a smaller aperture (larger f-number).
Multiple flash operation
Optional accessories
You can use additional flash units to eliminate harsh shadows cast by the
subject on the background or to create special lighting effects not possible
with a single flash unit.
Multiple flash operation can be accomplished in two ways:
(1) By connecting a Speedlight to the camera using a sync or remote cord such as
TTL Remote Cords SC-17 or SC-24 or TTL Multi-Flash Sync Cords SC-18 or SC-19.
(2) By mounting a Speedlight on the Wireless Slave Flash Controller SU-4.
In both cases, TTL multiple flash operation is possible with Nikon cameras having a
TTL Auto Flash mode capability. Manual multiple flash operation is possible with any
Nikon camera.
•Read your Speedlight and accessories instruction manuals for details.
Multiple flash operation using a sync or remote cord
•SB-11, SB-14, SB-140 and SB-21B Speedlights cannot be used with Nikon
F-401/N4004 or F-401s/N4004s cameras.
•In multiple flash operation, if the electric current in the synchro circuits exceeds a
certain level, you may not be able to take second shot after the first. In this case,
disconnect the master flash unit from the camera. This resets the circuits so you can
resume shooting.
•To prevent the above from happening, take care that the combined total of the
coefficients in the table below for all flash units used together does not exceed 20 at
20 °C (68 °F) or 13 at 40 °C (104 °F).
•Refer to “Optional accessories” for sync or remote cords.
•Read each product’s instruction manual for details on connections.
Multiple flash operation using the Wireless Slave Flash Controller SU-4:
•TTL or Manual multiple flash operation is possible by using the camera’s built-in
Speedlight or a Speedlight mounted on the camera’s hot shoe as the master flash
unit, and one or more Speedlights mounted on Wireless Slave Flash Controllers SU-4
as the 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.
•These Nikon Speedlights are usable:
SB-29, SB-28, SB-27, SB-26, SB-25, SB-24, SB-23, SB-22s, SB-22, SB-20, SB-18,
SB-16B, SB-15
•Read the SU-4’s instruction manual for more details.
■ TTL multiple flash operation
Connect the master flash unit to the camera directly. Or use the TTL
Remote Cord SC-17/SC-24 instead.
Connect the master flash unit to the slave flash unit(s).
•Use one or more TTL Remote Cords SC-18/SC-19 for direct connection or use
these cords in combination with the TTL Multi-Flash Adapter AS-10.
•Use the Wireless Slave Flash Controller SU-4 for remote control of one or more
slave flash units in the TTL flash mode.
Set each flash unit by considering its direction and distance.
•Please note that the brightness of flash illumination is inversely proportional to
the square of the distance between the flash unit and the subject when the same
Speedlight models are used for both the master and slave flash units.
For example, if the flash-to-subject distance is a reference unit of 1, the
brightness will be one-half that when the subject is 1.4 times away, and one-
quarter when the subject is twice as far away.
Turn on all flash units and make sure their standby functions are not activated.
Set the flash mode on all flash units to TTL.
Follow the same procedures as in normal TTL Auto Flash “TTL” mode.
Note
TTL multiple flash operation is not possible with Nikon New FM2, FM10 and FE10
cameras. In this case, perform manual multiple flash operation using the TTL
Multi-Flash Adapter AS-10 or Wireless Slave Flash Controller SU-4.
■ Manual multiple flash operation
Attach the SB-29 to the camera’s accessory shoe.
Connect the SB-29 to the sync flash terminal of the slave flash unit(s).
•Use the same cords as used for TTL multiple flash operation, or Sync Cords
SC-11 or SC-15.
•Use the Wireless Slave Flash Controller SU-4 for remote control of one or more
slave flash units in the Manual flash mode.
Set each flash unit by considering its direction and distance.
(See the note in item 3 above regarding the relationship between brightens of flash
illumination and distance.)
Turn on all flash units and make sure their standby functions are not
activated.
Set the flash mode of all the flash units to Manual M.
Follow the same procedures as in normal Manual flash “M” mode. 6

Autofocus operation in dim light
■ AF assist illuminator lamp
When the light is too dim for normal autofocus operation, the SB-29’s AF
assist illuminator lamp can be used to illuminate dark subjects.
Press the AF assist illuminator lamp button to turn the lamp on. 1
Press the AF assist illuminator lamp button again to turn the lamp off.
•The AF assist illuminator lamp turns off automatically when the SB-29 is fired. It
also turns off after approx. 1 min. if the SB-29 is not touched.
Note
If the shooting distance is 150mm or less, light from the AF assist illumination may
appear in the final shot and affect the camera’s exposure. Therefore, be sure to turn
off the illuminator lamp before shooting.

Tips on Speedlight care
Troubleshooting
•Use a blower brush to remove dirt and dust from the SB-29 and clean it with a soft, clean cloth. Never use
commercial cleaners containing thinner or benzene as they could damage its plastic parts.
•When storing the SB-29 for two weeks or longer, remove the batteries to prevent battery leakage. Also once a
month, insert fresh batteries and fire the unit several times to reform its capacitor and keep the SB-29 in top
working order. Make sure to turn the power off before removing the batteries.
•Keep the SB-29 away from chemicals such as camphor or naphthalene. Also avoid exposing it to magnetic
waves from TVs or radios.
•Never store the SB-29 in the truck or glove compartment of a vehicle during the summer. Also, do not place it
in front of a heater.
Notes on Batteries
•Battery power tends to weaken as the temperature drops. At low temperatures, the number of flashes decrease
and recycling time is longer. NiCd, Ni-MH and lithium batteries feature greater efficiency at low temperatures,
usable as low as –20°C (–4°F). Alkaline-manganese and zinc-carbon batteries are not recommended as their
performance become noticeably degraded at –10°C (14°F) for alkaline-manganese and 0°C (32°F) for zinc-
carbon batteries.
Please note that battery performance may differ from brand to brand, due to modifications or improvements in
performance.
Using lithium batteries (rated voltage: 1.5V)
•Lithium batteries incorporate internal safety switches. When they become hot, their safety circuits are
activated, cutting off power. Battery power will recover if you stop using them and allow them to return to
normal temperatures.
Using rechargeable NiCd and Ni-MH batteries
•Overcharging and excessive use may shorten battery life. Always make certain to turn the SB-29 off when not
in use.
•Because flash consumes a large amount of battery power, rechargeable batteries may not operate properly
before reaching the end of their stated life-span or the number of charging/discharging as specified by the
battery manufacturer.

Warnings
•Do not attempt to disassemble, repair, or modify the flash unit yourself, as it houses
high-voltage circuitry that can cause an electric shock. Also, these action may cause
the unit to malfunction, resulting in bodily injure to yourself.
•If the flash unit is dropped and damaged, do not touch any exposed interior metal
parts, as it houses high-voltage circuitry that can cause an electric shock. Remove
the batteries and take the Speedlight to your local Nikon dealer for repair.
•If you detect heat, smoke, or the smell of burning coming from the Speedlight, stop
operation immediately and turn the flash unit off. Let the flash unit cool off before
removing the batteries. Then take the flash unit to your local Nikon dealer for repair.
•The SB-29 should not be exposed to rain or saltwater, as this may result in an electric
shock or cause the unit to catch on fire. Also never touch the flash unit with wet
hands.
•Do not operate the flash unit in an environment containing a combustible gas, as this
may cause the unit to catch on fire or result in an explosion.
•Keep batteries out of the reach of children. If a battery is accidentally swallowed, call
a doctor immediately.
•When replacing batteries, replace all four at the same time. Also, do not mix battery
types or brands or use old with new batteries. Otherwise, the batteries may catch on
fire or explode, due the possible leakage of corrosive liquids.
•In the event that corrosive liquids do seep from the batteries, avoid touching the
liquids. Certain types of batteries contain strong alkaline liquids which can cause
chemical burns. If the alkaline liquids stick to your skin or clothes, wash immediately
with running water.
Caution
•Do not fire the flash directly into a person’s eyes at close range as this may cause
temporary blindness.
•Keep the SB-29 out of the reach of children. This will prevent them from swallowing
accessories, batteries, or receiving an electric shock.
•Do not throw used batteries into a fire. Do not short circuit, disassemble, or heat
batteries; this may cause them to explode or catch on fire.
•Always follow the warning instructions printed on batteries to prevent them from
becoming hot, leaking corrosive liquids, catching on fire, or exploding.
•When recharging NiCd or Ni-MH batteries, be sure to use the battery charger
specified by the battery maker and read the instructions thoroughly. Do not recharge
NiCd or Ni-MH batteries with their terminals reversed in the charger or before the
batteries have cooled off sufficiently, as this may cause them to leak corrosive
liquids, become hot, catch on fire, or explode.
•Non-rechargeable batteries such as zinc-carbon, alkaline-manganese and lithium
batteries should never be charged in a battery charger as they may become hot,
catch on fire, explode or leak corrosive liquids.
•Always use the batteries specified in this instruction manual. Using other batteries
may cause them to become hot or catch on fire.
