Autofocus Speedlight

Instruction Manual

Foreword

Congratulations. You are now the proud owner of the Nikon Autofocus Speedlight SB-28, a flash unit offering sleek new styling and simple push-button operation. When used with Nikon SLR cameras, the SB-28s extensive capabilities range from 3D MultiSensor Balanced Fill-Flash, todays most advanced flash technology, to full manual operation. To get the most out of your new flash unit, please read this manual before use.

WARNINGTo avoid injury

Do not fire the flash directly into a persons eyes at close range as this may damage the retina, leading to partial or complete blindness. Avoid touching the front of the flash head while using the SB-28. The flash head generates significant heat during normal operation, which could cause burns. Do not expose the SB-28 to water as this may result in electric shock or cause the unit to catch on fire.
Determine which group your camera belongs to. In this manual, Nikon SLR cameras are divided into seven groups (I to VII) unless otherwise noted. First consult the camera group table to see which group your camera belongs to. Then as you read the manual, you will find specific information on how to use the SB-28 with your particular camera.
Please open the front fold-out page for easy reference.

Non-TTL Auto Flash Mode

For cameras in all groups In Non-TTL Auto Flash shooting, the SB-28s light output automatically changes to match the flash-to-subject distance. The light, however, is not measured through the lens, but is measured by the light sensor on the front of the SB-28.
The SB-28 can be used in Non-TTL Auto Flash mode with any Nikon camera/lens combination at any ISO film speed. You can choose apertures from f/2 to f/16 at ISO 100.
Press the button until appears on the LCD panel.

Set the cameras exposure mode to Aperture-priority auto (A) or Manual (M).
4 Set the aperture on the lens.
Set the aperture that appears on the SB-28s LCD panel on the lens. The subject will be overexposed if you set a larger aperture (smaller f-number) on the camera than on the SB-28, and underexposed if you set a smaller one (larger f-number).
5 Set the correct shutter speed.
Set the camera to its highest flash sync shutter speed.

Advanced operation

For handling difficult lighting situations or expressing your ideas
In addition to convenient Auto Flash, the SB-28 offers a host of other advanced operations to match your creative ideas or when unusual lighting situations are encountered.

Manual Flash Mode

For cameras in all groups Manual flash photography is provided when shooting subjects in which the correct exposure is difficult to obtain in the TTL or NonTTL Auto Flash Mode. Flash settings
2 Adjust the flash output level.
Press the { or } button to choose a flash output level. Exposure compensation value Flash output level
The indicator changes every time you press the } button: 1/1(0.0) 1/2(0.0) 1/2(-0.3) 1/2(-0.7) 1/4(0.0) 1/64(0.0) %
The indicator changes every time you press the { button: % 1/64(0.0) 1/64(+0.3) 1/64(+0.7) 1/32(0.0) 1/2(0.0) 1/1(0.0)
The numbers in parentheses ( ) represent the adjustable flash output level in 1/3 steps. The indicator bar on the LCD panel changes to match the shooting distance at the flash output level set, and the corresponding exposure compensation value is displayed on the LCD panel.

If the angle of the flash head is not far enough off axis from the subject, uneven illumination will result from a combination of direct and bounced flash. In color photography, select white or highly reflective surfaces to bounce light off of. Otherwise, your pictures will come out with an unnatural color cast similar to that of the reflecting surface.
Applicable to all camera groups
Flash head tilting and rotating angle
For bouncing light off the walls or when the camera is held vertically, the SB-28s flash head tilts up to 90 and rotates horizontally 180 (to the left) and 90 (to the right). Always set the flash head at a click stop.
When the flash head is tilted up or rotated from the horizontal/front position, the shooting range indicator bars _ on the LCD panel disappear and the SB-28s Monitor Preflash does not operate. The shooting range indicator bars _ blink when the flash head is tilted down to the 7 position. This position is used when shooting subjects 1.5m (approx. 5 ft) or closer.
to 5 Wait for the ready-lightthe come on and make sure the subject is in focus before taking picture.
If the ready-light blinks for approx. 3 seconds after shooting, the flash fired at its maximum output, indicating the light may have been insufficient for correct exposure. In that case, use a wider aperture or move closer to the subject. In bounce flash operation, no shooting range indicator bars _ appear. Therefore, you should check the distance between the flash head and the bounce surface, between the bounce surface and the subject, and the angle of tilt or rotation of flash head, then bracket your exposures by 1 or 2 stops.
Using the built-in bounce card
In bounce flash photography, you can create a highlight in the subjects eyes by using the SB-28's built-in bounce card. This white card reflects a small amount of light directly back to the subject, opening up the shadows and making the eyes look more vibrant.
1 Pull out the wide flash adapter.
bounce 2 While holding thethe flash card, slide the wide flash adapter back into place inside head.
After sliding the wide flash adapter back into place, pull out the bounce card gently as far as it goes. Be careful not to force the bounce card.
3 Set the flash head as shown and take pictures.

Flash shooting with more than one unit Flash shooting with one flash unit
For multiple flash operation with the SB-28, both TTL Auto Flash t and Manual Flash modes are possible.
Multiple flash operation in TTL Auto Flash t mode is possible with cameras in Groups I through VI and F3-Series cameras. Multiple flash operation in Manual Flash mode is possible with cameras in all groups. For applicable flash units and accessories, see pages 68-69, System chart for TTL multiple flash. In multiple flash operation, first decide which will be the main unit and which the secondary unit(s). To eliminate shadows, adjust the lighting ratio so that illumination from the main unit is greater than that from the secondary unit(s).
Notes on multiple flash operation
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 SB-28 unit from the camera. This resets the circuits so you can resume shooting. In multiple flash operation, take care that the combined total of the coefficients (numbers shown in parentheses below) for all flash units used at the same time does not exceed 20 at 20C (68F), or 13 at 40C (104F).

TTL multiple flash operation
Cameras in Groups I through VI and F3-Series
1 Attach the main flash unit to the cameras accessory shoe. 2 Set the flash mode of the master flash unit to t mode.
To use the SB-28 off-camera, refer to pages 68-69, System chart for TTL multiple flash, for the correct type of optional TTL Remote Cord to use.
To obtain the correct exposure with the SB-28 when used as the main flash and set to 3D Multi-Sensor Balanced Fill-Flash, cancel Monitor Preflash on the main flash unit by pressing the button until t appears on the LCD panel.
3 Connect the main flash unit to the secondary flash unit(s).
Use one or more TTL Remote Cords SC-18 or SC-19 to connect the SB-28 to the secondary flash unit(s) in series.
Turn off all flash units before connecting. Use Multi-Flash Adapter AS-10 when using more than three flash units for TTL multiple flash operation, or if the secondary flash units are not equipped with multiple flash terminals. Use Tripod Adapter AS-11 to attach the SB-16A or SB-17 to a tripod.

Canceling exposure compensation
Flash exposure compensation cannot be canceled by turning the SB-28 off. To cancel, reset the exposure compensation to 0.0 following the steps outlined above.
For cameras in Groups I through VI (when making exposure compensation to the SB-28s flash output and the background)
Use your camera's EV compensation control to make exposure compensation. In this mode, flash output is automatically controlled to keep both subject and background correctly exposed.
For more details, refer to your camera's instruction manual. The SB-28's LCD panel does not display the amount of compensation set on the camera. With cameras in Groups I and II, the shooting range indicator bars _ automatically change according to the amount of exposure compensation. For cameras other than those in Groups I and II, use this chart as a guide in obtaining the correct flash shooting distance range.
Exposure compensation values possible with various film speeds
Exposure compensation value Film speed ISO 25 ISO 50 ISO 100 ISO 200 ISO 400 ISO 800/1000

100 200

For example, with ISO 100 film, if you want to make an exposure compensation of +2 steps on the camera, set the film speed on the SB-28s LCD panel to ISO 25, then check the flash shooting distance range. For cameras in Groups I through VI, exposure compensation in the TTL Auto Flash t mode is not possible when the film speed exceeds those listed above. In this case, set the flash mode to Non-TTL Auto Flash or Manual Flash mode.
Flash exposure compensation in Non-TTL Auto Flash mode
In this mode, if you dont set the same aperture on the lens as that set on the SB-28, you cannot obtain the correct exposure. Therefore, to make exposure compensation, vary the aperture set on the camera while retaining the aperture set on the SB-28.
Read the flash shooting distance range as shown on the SB-28 without changing the aperture set on the SB-28.
Flash exposure compensation in Manual Flash mode
In this mode, you can obtain the correct exposure by balancing three factors: flash output level, flash-to-subject distance, and aperture. You can calculate a correct aperture and flash shooting distance range by using the guide number equations on page 56.

Autofocus flash operation in dim light
For autofocus cameras only When the light is too dim for normal autofocus operation, the SB-28s AF assist illuminator LED automatically turns on when set to illuminate dark subjects when the shutter release button is pressed halfway.
Take care not to block the AF assist illuminator LED while shooting. The AF assist illuminator LED turns off as soon as the subject is in focus. The AF assist illuminator LED will not light up with an F5, F100, F80-Series/N80-Series or F65-Series/N65-Series camera unless the cameras central focus area is selected.
For autofocus cameras only
Conditions necessary to activate the AF assist illuminator LED:
1 The subject must be sufficiently dark and within the range of 1m (3.3 ft) to 8m (16.4 ft) at 20C (68F). 2 AF Nikkor lenses must be used.
Lenses from 24mm (35mm for F-501/N2020) to 105mm are recommended. Other AF Nikkor lenses can be used depending on shooting conditions. Perform test firing before use.
3 The camera's autofocus mode is set to Single Servo Autofocus (S). 4 Focus lock is not employed. 5 The SB-28s ready-light is on.
Replace batteries whenever the ready-light becomes dark or blinks after the AF assist illuminator LED turns on.
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 outside the flash shooting distance range. In this case, set the cameras focus mode selector to manual and focus manually.
To cancel autofocus flash operation with the AF assist illuminator LED
Hold down the button as you press the } button.
The ; indicator comes on or disappears on the LCD panel every time you press the and } buttons simultaneously. The AF assist illumination LED is set when the ; indicator is not on and canceled when the ; indicator appeared. The AF assist illumination LED is preset to operate when the SB-28 is shipped from the factory.

Notes on batteries

WARNING
Keep batteries out of the reach of children. If a battery is accidentally swallowed, call a doctor immediately.
Notes on handling batteries
Do not expose batteries to excessive heat. Never store them in the truck or glove compartment of a vehicle during the summer or place them near a fire or hot surface. Even hot, direct sunlight may cause them to explode. When loading batteries, make sure the SB-28 is turned off, then follow the + and symbols inside the battery chamber. If the SB-28 is not used for more than two weeks, remove the batteries and store them in a dry place at 20C (68F) or below. Battery power tends to weaken as the temperature drops. It also weakens after heavy use, recovering gradually after a short break. Power gradually decreases when batteries are not used for a long time. Check battery power before use; replace batteries with a new set before they are completely exhausted. Battery performance may differ with each brand, due to modification in specifications or improvement in performance.
Four AA-type alkaline-manganese, lithium, or rechargeable NiCd or Nickel-Metal Hydride (Ni-MH) batteries are required to power the SB-28.
For fast recycling times: NiCd batteries are recommended followed by (2) Ni-MH, (3) alkaline-manganese, and (4) lithium batteries. For increasing the number of flashes per battery set: at normal temperatures, lithium batteries are recommended followed by (2) alkalinemanganese, (3) Ni-MH, and (4) NiCd batteries; at low temperatures, lithium batteries are recommended followed by (2) Ni-MH, (3) alkalinemanganese, and (4) NiCd batteries. Ni-MH batteries feature approx. the same battery power as 1000mAh NiCd batteries. 1000mAh NiCd batteries have approx. 1.4 times the power capacity of 700mAh NiCd batteries.
Lithium batteries have approx. 1.1 to 1.2 times the power capacity of alkaline-manganese batteries. Lithium batteries feature greater efficiency at low temperatures when compared with alkaline-manganese batteries. Lithium batteries boast consistent performance in terms of recycling times and number of flashes, regardless temperature changes. NiCd batteries boast a constant recycling time regardless of temperature changes when compared with other types of batteries. Recommended for use in temperatures as low as 0C (32F). Ni-MH batteries feature a constant recycling time but a little longer recycling time at low temperatures when compared with NiCd batteries. However, Ni-MH batteries maintain their efficiency regarding the number of flashes regardless of temperature changes.
Notes on using alkaline-manganese and lithium batteries

Non-rechargeable batteries such as alkaline-manganese and lithium batteries should not be charged in a battery charger as they may explode. Lithium batteries incorporate internal safety switches. When the battery becomes hot, its safety circuit is activated, cutting off power. This often occurs when the SB-28 is operated in the repeating flash mode. The flash ready-light will not light up after firing approx. 24 exposures. However, battery power will recover when the temperature goes back to normal.
Notes on using rechargeable NiCd and Ni-MH batteries
When recharging batteries, be sure to use the battery charger specified by the battery maker and read the instructions thoroughly. Recharging should be done in temperatures from 10 to 30C (50 to 86F). Do not recharge NiCd or Ni-MH batteries with their terminals reversed in the charger or before the batteries have cooled off sufficiently. Overcharging and excessive use may shorten battery life. Do not overcharge and be sure to turn the SB-28 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. If NiCd or Ni-MH batteries do not last as long as they should after being fully charged, they are approaching the end of their life. Replace them with a new set.

Introduction

Thank you for purchasing the Nikon Autofocus Speedlight SB-28DX. The SB-28DX is a special version of the Nikon Speedlight SB-28 that features a D-TTL Auto Flash mode for Nikon Digital SLR cameras, and an Auto Aperture (AA) mode for Nikon Digital SLR cameras and Kodak DCS600 Series digital cameras. This instruction manual describes how to use the SB-28DX in the D-TTL Auto Flash mode with Digital SLR cameras and the AA mode with Digital SLR cameras and Kodak DCS600 Series cameras. Of course, the SB-28DX works well with film-based Nikon cameras such as the F5 and F100.

A flash shooting distance range of 0.8 to 6m (3 to 20 ft.) is shown.
If the subject is out of range, change the aperture on the camera to bring the subject within the flash shooting distance range.

If the ready-light blinks for approx. 3 seconds after the picture is taken, this indicates the flash fired at maximum output, meaning that light may have been insufficient for correct exposure. In that case, use a wider aperture or move closer to the subject before taking the next picture by referring to Table 2. To check the correct flash shooting distance range before taking the picture Point the camera at the subject. After pressing the shutter release button lightly, press the ~ button on the SB-28DX. If the ready-light blinks for approx. 3 seconds, this indicates the flash fired at maximum output, meaning that light may have been insufficient for correct exposure. In this case, use a wider aperture or move closer to the subject by referring to Table 2 before taking the actual picture. Table 2: Usable aperture/flash shooting distance ranges in AA (Auto Aperture) and A (non-TTL Auto Flash) modes Use this table to determine the distance range in which the correct auto flash exposure will be obtained at various ISO sensitivity levels, aperture, and zoom settings.

In this mode, the SB-28DX fires a series of nearly invisible preflashes, called the Monitor Preflash. These preflashes are detected by the cameras TTL multi-sensor to control the flash output, ensuring correct exposure. Data such as the cameras ISO setting, aperture, focal length, and exposure compensation value are automatically transmitted to the SB-28DX (with Nikkor lenses with a built-in CPU mounted.) The following four flash modes are possible depending on the type of lens mounted. Lens mounted

Flash exposure compensation
In AA mode, flash output compensation is possible in 1/3 steps from 3.0 to +1.0EV by pressing the { or } button to increase or decrease the compensation while confirming the amount on the LCD panel. Note that flash output compensation is restricted in Zones A to D. Zone A: Minus flash output compensation is not possible. Zone B: Flash output compensation exceeding 1EV is not possible. Zone C: Flash output compensation exceeding 2EV is not possible. Zone D: Flash output compensation from 0 to +1EV is not possible. If flash output compensation is made exceeding the amount of the above values, the flash shooting range indicator bars disappear and the aperture, exposure compensation indicator, and exposure compensation value blink to warn you. Exposure compensation on the camera is possible. Refer to your cameras instruction manual for information. Exposure compensation can be made on both the SB-28DX and the camera. The exposure is controlled by the sum total of both exposure compensation values and the shooting range indicator bars changes to match the exposure compensation. However, the SB-28DXs LCD panel displays the amount of compensation set on the SB-28DX only.
