Flash operation
Monitor preflash data is integrated with the
distance information from D-type Nikkor
lenses to obtain correct TTL auto flash
operation.
Based on camera’s Matrix Metering system
and monitor preflash data, flash output is
automatically controlled to keep both
subject and background correctly exposed.
Measuring background ambient light
using Center-Weighted metering system,
flash output is controlled using monitor
preflash data to keep both subject and
background correctly exposed.
Select the flash mode.
– Press the µ button once to display D tØor D tøon
the LCD panel. Press the µ button again to display D t on the
LCD panel.
Check the shooting distance using the flash shooting range
indicator bars.
– If the subject is out of range, change the aperture on the camera to bring
the subject within the flash shooting distance range.

LCD panel
The LCD panel on the SB-28DX differs slightly from that of the SB-28 (+ pages 4–5).
Wait for the ready-light to come on before taking
the picture.
– 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.
Select the flash mode.
– Press the µ button until
˙
appears on the LCD panel in either AA
(Auto Aperture) or A (non-TTL auto) mode. In AA mode, the exposure
compensation indicator and exposure compensation value appear on the
LCD panel simultaneously.
– When the flash unit is mounted on the Kodak DCS620 camera and turned
on for the first time, the AA mode is always activated.
Table 2: Usable aperture/flash shooting distance ranges in AA (Auto Aperture)
and A (non-TTL Auto Flash) modes

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 camera’s 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-28DX’s LCD panel displays the amount of compensation set on the
SB-28DX only.
SB-28DX settings
Taking flash photographs in the D-TTL Auto Flash mode
In this mode, the SB-28DX fires a series of nearly invisible preflashes, called the Monitor
Preflash. These preflashes are detected by the camera’s TTL multi-sensor to control the
flash output, ensuring correct exposure. Data such as the camera’s 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.

Wait for the ready-light to come on before taking
the picture.
– If the ready-light and the underexposure indicator blink 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 the amount of underexposure
(up to –3 EV) appearing on the LCD panel. (If “–1.0” is displayed, reshoot
using an aperture that is at least one stop wider.)
– You can recall the amount of underexposure last shown on the LCD panel
by pressing the
. button.

– In P (Programmed auto) exposure mode: Set the lens aperture to its
minimum.
•In either exposure mode, if the aperture is out of the range, the aperture
value, exposure compensation indicator and exposure compensation
value on the LCD panel blink and the flash shooting distance range
indictor bars disappear to warn you. In this case, adjust the aperture and
shooting distance by referring to Table 2.
In this mode, the correct exposure for both subject and background is automatically
obtained. The SB-28DX’s built-in sensor controls the flash output in combination with
data transmitted from the camera and lens to the SB-28DX, including the ISO sensitivity
level, aperture, focal length, and exposure compensation value.
– AA (Auto Aperture) mode only works when using the Digital SLR or DCS600 Series
cameras when Nikkor lenses with a built-in CPU (except IX Nikkor lenses and AF Nikkor
lenses for the F3AF) are mounted (+ page 7). The AA mode is automatically switched
to Non-TTL Auto Flash
A
mode (+ page 42) when Nikkor lenses without a built-in
CPU are mounted.
