Flash Readiness Indication; Automatic Flash Sync Speed Control - Metz SCA 3402 M10 Manual Del Usuario

6.2 Flash readiness indication

The flash ready symbol
unit when the flash capacitor is charged, thereby
indicating that flash readiness is established and
that flashes can be fired for the next shot. Flash
readiness is also transmitted to the camera for a
corresponding display in the viewfinder (see came-
ra manual).
If a picture is shot before flash readiness is indica-
ted then the flash unit will not be triggered so that
the exposure may be incorrect if the camera has
changed over to flash sync speed in the meantime.

6.3 Automatic flash sync speed control

Depending on the camera type and camera mode,
the shutter speed changes to flash sync speed (see
operating instructions for the camera).
Shutter speeds faster than the flash sync speed
cannot be set or will automatically be converted to
flash sync speed. Various cameras have a sync
speed range, e.g. 1/30 sec. to 1/125 sec. (see
camera manual). The actual sync speed set by the
camera depends on the camera mode, the ambient
light and the focal length of the lens. Shutter
speeds slower than the flash sync speed can be
used, depending on the camera mode and the sel-
ected flash synchronisation.
On various digital cameras there is no auto-
matic flash sync speed control. Such cameras
work with a diaphragm shutter and permit the
flash to be used at all shutter speeds.
