Setting Setting Description Description
A Flash control mode
Choose from the following options:
•
M: A trigger signal is transmitted from the sync terminal and
hot shoe when a picture is taken. Choose a shutter speed
slower than the sync speed; even slower speeds may be
required if the unit uses long fl ashes or has a slow response
time.
•
OFF: The sync terminal and hot shoe do not transmit a trig-
ger signal.
B Sync
Choose whether the fl ash is timed to fi re immediately after
the shutter opens (
H/1ST CURTAIN) or immediately before
it closes ( I/2ND CURTAIN). 1ST CURTAIN is recommended in
most circumstances.
The Sync Terminal
Use the sync terminal to connect fl ash units
that require a sync cable.
