11 Flash readiness indication

✴
When the flash capacitor is charged, the flash readi-
ness symbol
that the flash is ready to fire. This means that flash light
can be used for the next shot. Flash readiness is also
transmitted to the camera and indicated accordingly in the camera's viewfinder.
If a shot is taken before the flash readiness indicator appears in the camera's
viewfinder, then the flash unit will not be triggered and, if the camera has alrea-
dy switched to flash sync speed (see 12), the shot may have the wrong exposu-
re.
☞ The multi-zone AF measuring flash
be activated by AF cameras only when flash readiness is indicated (see
17).

12 Automatic flash sync speed control

Depending on the camera model and camera mode, the shutter speed is swit-
ched to flash sync speed when flash readiness is reached (see the camera's ope-
rating instructions).
Shutter speeds cannot be set faster than the flash sync speed, or they are swit-
ched automatically to the flash sync speed. Various cameras have a sync speed
range, for example from 1/30 sec. to 1/125 sec (see the camera's operating
instructions). The sync speed set by the camera depends on the camera mode,
the ambient light, and the focal length of the lens used.
Shutter speeds slower than the flash sync speed can be set according to the
camera mode and the selected flash synchronisation (see also the camera's ope-
rating instructions and 15).
☞ If a camera with a between-the-lens shutter (see the camera's operating
instructions) or HSS synchronisation (see 15.4) is used, flash sync speed
is not controlled automatically. As a result, the flash can be used at all
shutter speeds. If you need the full light output of the flash unit, you
should not select a shutter speed that is any faster than 1/125 sec.

13 Correct exposure indication

The correct exposure indication „OK"
if the shot was correctly exposed in TTL flash mode or
automatic flash mode.
If no „OK" exposure indication
underexposed. You will need to repeat the shot with the next smaller f-number
(for example, f/8 instead of f/11), or the distance to the subject or reflecting
surface (for example with bounce flash) will have to be reduced. Note the maxi-
mum flash range indicated on the display of the flash unit (see 14).

14 Flash range indication

The maximum flash range is indicated on
the display panel of the flash unit. The
value indicated relates to subjects with a
reflection factor of 25%, which applies to most photographic situations. Strong
deviations from this reflection factor, as in the case of highly reflective or poorly
reflective subjects, may affect the flash range.
In TTL- and automatic flash mode, the subject should be in the middle third of
the indicated range. This will give the automatic exposure control sufficient sco-
pe for compensation.
To avoid overexposure, the minimum distance from the subject should be no less
than 10% of the indicated value. An adjustment can be made to a particular
photographic situation by changing the aperture setting, for example.
In manual flash mode M, the distance that must be maintained from the subject
for correct flash exposure is indicated. An adjustment to the photographic situa-
tion at hand can be achieved by, for example, changing the aperture setting on
the lens and by selecting either full light output or „P" for a partial light output
level.
☞ The flash range can be expressed in either meters (m) or feet (ft) according
to the chosen setting (see 7.7). There is no flash range indication in remote
mode or when the main reflector is swivelled or tilted.
