Taking Photographs—Flash Photography
Notes on Optional Speedlights
Refer to the Speedlight manual for detailed instructions. If the Speedlight supports
i-TTL or D-TTL fl ash control, refer to the entry for digital SLR cameras in the table of
camera types.
If Auto FP High-Speed Sync is not used, the shutter will synchronize with an external
ash at speeds of ½
50 s or slower.
If the fl ash-ready indicator blinks for about three seconds after a photograph is taken
with i-TTL or D-TTL fl ash control, the photograph may be underexposed.
The SB-28DX displays exposure in increments of
1
/
3 EV. If the camera is set to control
exposure in increments of ½ EV using Custom Setting b2, the SB-28DX exposure dis-
play will not show the correct ISO value. The actual exposure value is not affected.
i-TTL and D-TTL fl ash con trol can be used to adjust fl ash out put at sensitivity (ISO
equiv a len cy) set tings be tween 200 and 1600. At settings of HI-1 and HI-2, the desired
re sults may not be achieved at some ranges or aperture settings.
The AF-assist il lu mi na tor on SB-series 80DX, 28DX, 28, 27, 26, and 24 Speedlights will
only light if all of the fol low ing con di tions are met: focus mode is set to single-servo
auto, an AF-Nikkor lens is used, the subject is poorly lit, and the center focus area is
selected or dynamic-area AF is used in com bi na tion with clos est-subject priority.
In programmed auto, the maximum aperture (minimum f/-number) is lim it ed ac-
cord ing to sen si tiv i ty (ISO equivalency), as shown below:
For each one-step increase in sensitivity (e.g., from 200 to 400), aperture is stopped
down by half an f/-stop. If the maximum aperture of the lens is smaller than given
above, the maximum value for aperture will be the maximum aperture of the lens.
When an SC-series 17, 28, or 29 sync cable is used for off-camera fl ash photography,
correct exposure may not be achieved in i-TTL or D-TTL mode. We recommend that
you choose spot metering to select standard i-TTL or D-TTL fl ash control. Take a test
shot and view the results in the monitor.
In i-TTL or D-TTL mode, use the fl ash panel provided with your Speedlight. Do not use
other panels such as diffusion panels, as this may produce incorrect exposure.
D-TTL fl ash control can not be used for multi-fl ash photography.
