Notes and tips for optional ash units
When using an optional ash unit, be sure also to read the
documentation supplied with the unit.
If the unit supports CLS, refer to the section on CLS-compatible
digital SLR cameras. This camera is not included in the “digital SLR”
category in the documentation for the SB-80DX, SB-28DX, and
SB-50DX.
If the ash-ready indicator (
c
) ashes for about three seconds after a
photograph is taken in i-TTL or non-TTL auto mode, the ash has red
at full power and the photograph may be underexposed (CLS-
compatible ash units only).
i-TTL ash control can be used at ISO sensitivities between 100 and
12800.
At ISO sensitivities over 12800, the desired results may not be
achieved at some ranges or aperture settings.
In mode P, the maximum aperture (minimum f-number) is limited
according to ISO sensitivity, as shown below:
Maximum aperture (f-number) at ISO equivalent of:
100 200 400 800 1600 3200 6400 12800
4 5 5.6 7.1 8 10 11 13
