4 LED displays on the flash unit
4.1 Flash readiness indication
When the flash capacitor on the flash unit is
charged, the
ቧ button lights up in green,
thus indicating that the flash unit is ready.
This means that flash light can be used for
the next shot. Flash readiness is also trans-
mitted to the camera and indicated accordin-
gly in the camera's viewfinder.
If a photograph is taken before the display
for flash readiness appears in the camera’s
viewfinder, then the flash unit will not be trig-
gered. If the camera has already switched to
flash sync speed, the shot may have the
wrong exposure (see 12.1).
4.2 Correct exposure indication
If the exposure is correct, then button ቨ
lights up in red for around 3 seconds if the
photograph has been correctly exposed in
flash modes P TTL (
) and P TTL HSS
( )) (see 6.1).
If there is no exposure control indication after
the shot, then the photograph was underex-
posed. In that case, you must:
- set the next smaller f-stop (e.g. use f-stop 8
instead of 11), or
- reduce the distance to the subject or to the
reflection surface (e.g. for indirect flashes),
or
