Flash Photography
In addition to TTL, flash modes such as Non-TTL Auto flash and manual flash
are available. Flash mode availability depends on the type of Speedlight used;
for details, see the instruction manual of the Speedlight.
• Auto Aperture Flash (AA)
The Speedlight’s built-in sensor measures the flash illumination reflected from the
subject and controls flash output in combination with data automatically transmitted
from the camera and lens to the Speedlight, including ISO sensitivity and exposure
compensation values, and lens’ aperture and focal length.
• With the SB-80DX or SB-28DX, set Custom Setting “e3: AA flash mode” to “On”
(x 105). With the SB-800, the Speedlight setting overrides the Custom Setting.
• Non-TTL Auto flash (A)
The Speedlight’s built-in sensor measures flash illumination reflected from the subject,
automatically controlling the Speedlight’s light output to provide correct exposure. This
enables you to make exposure compensation (x 74) easily by varying the aperture
set on the camera or lens.
• With the SB-80DX or SB-28DX, set Custom Setting “e3: AA flash mode” to “Off”
(x 105). With the SB-800, the Speedlight setting overrides the Custom Setting.
• Aperture must be set manually on the Speedlight.
• Distance-Priority Manual flash (GN)
In this flash operation, the Speedlight controls the light output automatically based on
the shooting distance, aperture value and ISO sensitivity. Enter the shooting distance
and you can take pictures having the same exposure even when shooting at different
apertures.
• Manual flash (M)
In Manual flash photography, you select the aperture and flash output level. This
allows you to control the exposure and flash shooting distance when shooting subjects
where the correct exposure is difficult to obtain in TTL or Non-TTL Auto flash mode.
The flash output level can be set from M1/1 (full output) to M1/128 to suit your
creative preferences. (Usable flash output level depends on the Speedlight.)
• Repeating flash (RPT)
In Repeating flash operation, the Speedlight fires repeatedly during a single exposure,
creating stroboscopic multi-exposure effects. This feature is useful when shooting fast-
moving subjects.
• Manually set the flash output level, frequency (Hz), and number of repeating flashes
per frame.
