Leica SF 58 Instruction Manual page 71

The secondary reflector cannot be activated or no flash is triggered
• The secondary reflector does not support the flash modes stroboscopic,
M
-Slave and test light. In these modes, the secondary reflector cannot be
activated, or the secondary reflector does not trigger a flash.
• The main reflector is in its normal position or tilted downwards.
The flash sync speed is not automatically set
• The camera is operating with HSS-High Speed Synchronization (camera set-
ting).
In this case, automatic sync speed setting is not accessible.
• The camera is operating with shutter speeds that are slower than the flash
sync speed. Depending on the camera exposure mode, automatic sync speed
setting is not accessible (see camera's instr.).
The images are dark at the bottom.
Due to parallax error between lens and flash unit, close-up shots, depending
on the focal length, cannot be completely illuminated at the bottom of the ima-
ge. Tilt the main reflector downwards or place turn the wide-angle diffuser in
front of the reflector.
The shots are too dark.
• The subject is beyond the range of the flash unit. Note: Using bounce flash
reduces the range of the flash unit.
• The subject contains very bright or highly reflective areas. The metering
system of the camera or flash unit is deceived as a result. Set a positive
manual flash exposure compensation, e.g. +1 EV.
The shots are too bright.
In close-up shots, overexposure (shots that are too bright) may result if a flash
duration is necessary that is shorter than the flash can deliver. The minimum
distance from the subject should be at least 10 % of the maximum range indi-
cated on the monitor.
The flash parameters for ISO film speed and the aperture (f-stop) can-
not be adjusted on the flash unit.
Digital data exchange takes place between flash unit and camera. Thus the ISO
and aperture (f) values are automatically adjusted on the flash unit. In such
cases, manual setting of ISO and aperture is not possible!
