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
