SELECTING THE SYNC SPEED / THE SYNC SPEED RANGE
The Leica S allows you to combine flash operation with the shutter
speed used in the automatic program and aperture priority exposure
modes to subtly adjust the lighting conditions for the relevant subject
or to suit your picture composition ideas. You can choose between one
automatic and several manual settings.
Setting the function
5. In the
CAMERA menu (see p. 16/26), select Auto Slow Synch.. (5.6),
and
6. then the automatic lens-specific setting -
1/f - or whether you want
to determine a particular shutter speed yourself -
Manual Setting - in
the submenu.
7. In the
Manual Setting submenu, set the range of shutter speeds per-
mitted by determining the fastest speed permitted.
Notes:
•
1/f results in the slowest possible shutter speeds based on the rule
of thumb for blur-free pictures taken from the hand, e.g.
1
/
60
s with
the Summarit-S 70mm f/2.5 ASPH. However, in the
Manual Setting
menu it is limited to
1
/
125
s even if the focal length used is longer.
• The setting field in the
Manual Setting submenu initially contains the
"default setting" of
1/f.
SELECTING THE FIRING MOMENT
The Leica S allows you to choose between a flash firing moment at the
beginning or the end of the exposure.
The function is available with all flash units, including non-system com-
patible units, regardless of whether they are mounted in the flash shoe
or connected by a cable, and with all camera and flash unit settings.
The displays are identical in both cases.
Setting the function
1. In the
CAMERA menu (see p. 16/26), select Flash Synch Mode (5.7),
and
2. then the desired option, in the associated submenu.
ATTACHING THE FLASH UNIT
When attaching a flash unit to the Leica S flash shoe (1.14), you should
ensure that the foot of the flash unit is fully inserted and the clamping
nut (if available) is tightened to prevent it accidentally falling out. This is
particularly important for flash units with additional control and signal
contacts, because if the position in the flash shoe changes the neces-
sary contacts can be interrupted, leading to malfunctions.
Note:
Before attaching the flash, the camera and the flash unit must be turned off.
