Flash operating modes
The LEICASF 58 has a total of six flash modes:
TTL flash mode
-HSS TTL flash mode with HSS-High Speed Synchronisation
Automatic flash mode
Manual flash mode
-HSS Manual flash mode with HSS-High Speed Synchronization
-Slave Off-the-camera operation as secondary flash with wireless release
Strobe flash mode
Depending on the features of the camera, not all of these modes are available:
1
Function is intended only for off-the-camera operation as secondary flash. With
this function, the flash unit can only be triggered by another flash unit through its
slave-sensor.
2
Only with LEICAR 9
3
With metering pre-flash (see “TTL flash mode with metering pre-flash”, p. 56)
4
The function is inicated on the monitor of the flash unit, but is not supported by
cameras which only have one hot-shoe contact. It can therefore cause defective
exposures with these cameras.

TTL flash mode
With TTL flash mode, you can achieve very good flash shots easily. In this
mode, the exposure is measured by a sensor in the camera. It measures the
light entering the camera through the lens (TTL = “Through The Lens“).
The advantage of this flash mode is that all factors influencing the exposure
(filters, aperture changes, and focal length changes with zoom lenses, exten-
sions for close-ups, etc.) are automatically taken into account in controlling the
flash output.
TTL flash mode with metering pre-flash
The TTL flash mode with metering pre-flash with the digital Leica M- models is
a further development of the standard TTL flash mode of analog cameras.
Immediately after the shutter button is pressed, and before the actual expo-
sure, one or more almost invisible metering pre-flashes are executed by the
flash unit. The reflected light of the metering pre-flash/es is evaluated by the
camera. According to the evaluation, the subsequent flash exposure is adapted
to the photographic situation by the camera.
Notes:
• Depending on the camera model, the metering pre-flashes precede the main
flash by such a short interval that they cannot be practically distinguished
from the main flash!
• The metering pre-flashes do not contribute to the exposure.
