FLASH EXPOSURE DISPLAYS IN THE VIEWFINDER WITH SYSTEM-
COMPATIBLE FLASH UNITS
In the viewfinder display of the Leica S, a flash symbol serves as a feed-
back and display of various operating states.
•
does not appear despite the flash unit being switched on and ready
for use:
In such cases the Leica S will not fire the flash unit even though it is
switched on and ready for use. (e.g. because the wrong operating mode
is set on the flash unit)
•
flashes before the picture is taken:
– The flash unit is not yet ready to use
•
is lit up before the picture is taken:
– The flash unit is ready for use
•
continues to light up constantly after firing:
– The flash is still ready to use.
• In the case of a flash exposure compensation set at the flash unit
– ± appears additionally in the viewfinder as an indicator
FLASH PHOTOGRAPHY WITH THE FLASH UNIT-INTEGRATED AUTO-
MATIC COMPUTER
When working with the automatic exposure of system-compatible flash
units, the light reflected by the subject is metered and evaluated by a
sensor integrated into the flash unit, not by the camera. The exposure
operating modes of the camera function essentially in the same way as
without flash. If the flash sync speed drops below the set value with
P or
A , or a speed is set below the sync speed with T or M, the flash is not
triggered.
As the operating modes, and already generate a normally exposed pic-
ture due to the ambient lighting, the flash power should be reduced, i.e. a
flash exposure compensation of e.g. –1EV to –2EV should be set.
With system-compatible flash units, the aperture set at the lens is trans-
mitted to the flash unit and automatically taken as the basis as computer
aperture. For the metering, the sensitivity set at the camera and any
exposure compensation set for the ambient lighting (camera) and flash
(flash unit) are taken into consideration.
MANUAL FLASH PHOTOGRAPHY WITH CONSTANT FLASH POWER
If the flash unit is used in manual flash mode with full power or fixed
partial power (if this can be set at the flash unit), the emitted flash light
power is not controlled. The exposure operating modes of the camera
function essentially in the same way as without flash.
If the flash sync speed drops below the set value with
A or T , or a speed
is set below the sync speed with
T or M, the flash is suppressed. The lens
aperture to be set is determined by the flash power, sensitivity and
distance to the subject, or vice versa, the flash partial power to be set is
determined by the aperture, sensitivity, focal length and distance to the
subject (see flash unit manual).
FLASH PHOTOGRAPHY VIA THE X CONTACT
No information is transmitted if a non-system-compatible flash unit is
connected via the accessory shoe. As the camera cannot "recognize"
such a flash unit, it acts as if no flash unit were attached. The flash time
must be set manually to the flash sync speed
1
⁄125s, or
1
⁄1000s with central
shutter, or to slower speeds; an automatic changeover does not take
place. The flash unit ready and indicator lamps are not active.
If the flash unit is suitable, the light control can be performed with an
automatic aperture, i.e. via the sensor on the flash unit, or manually by
selecting corresponding partial light power levels (see flash unit manual).
FLASH PHOTOGRAPHY VIA THE LOWER LEMO
®
JACK
Flash units and large studio flash systems can be connected by cable
with LEMO
®
plug (supplied) can be connected to the lower LEMO
®
jack.
The LEMO
®
jack with its automatic locking reliably prevents an inadver-
tent interruption in the connection. As the camera cannot "recognize" a
flash unit connected in this way, it acts as if no flash unit were attached.
The flash time must be set manually to the flash sync speed
1
⁄125s, or
1
⁄1000s
with central shutter, or to slower speeds; an automatic changeover does
not take place. The flash unit ready and indicator lamps are not active.
