M 
Manual flash mode
Flash mode with unregulated light output. The flash unit delivers the full light output, if no partial light output
is set.
Manual zoom
The zoom position of the 
main reflector and thus the illu- mination of the flash unit can be adjusted
manually to the lens focal length.
Modeling light
Modeling light is a stroboscope 
light with a high flash frequency lasting a few seconds. With this “quasi per-
manent light”, the light dispersion and shadow formation at the subject can be checked before taking the photograph.
Motor zoom
The zoom position of the main 
reflector and hence the illumina- tion of the flash unit can be adjusted auto-
matically to the lens focal length.
P 
Partial light mode
Manual flash mode with unregu- lated light output. By setting par- tial light mode on the flash unit, the light
output or illumination duration of the flash unit can be adapted specifically to the pho- tographic situation.
P-TTL
Modern further development 
of the TTL flash control with measurement
Pentax and Samsung cameras.
R 
REAR
Synchronisation to the 2nd shutter curtain for more natural blurring
effects for longer exposure times.
Remote operation
A remote system consists of a master or controller flash unit on the camera and one or more slave flash
units. The slave flash unit is remotely con- trolled wirelessly by the master or controller flash unit. With a master flash unit, the flash light contributes to the exposure, in contrast to a controller flash unit.
S 
SCA 3002 adapter system
For system cameras with digital 
or analog data transmission be- tween the camera and flash unit. By using
an SCA adapter from the SCA 3002 sys- tem, there are numerous additional system flash functions available with flash units from the SCA 3002 system, depending on the type of camera. The firmware of an SCA adapter from the SCA 3002 system is updateable via Metz service for future cameras. The SCA 3002 adapters are an updated version of the SCA 3000 system.
SCA 300 adapter system
For system cameras for adapta- 
tion to flash units of the SCA 3002 or SCA 300 system. Depending on
the type of camera, not all system flash functions are supported by the SCA 300 system.
Secondary reflectorr
To brighten shadows cast in the
when using an indirect flash.
Slave mode
An integrated sensor makes this 
wireless slave flash mode pos- sible in combination with a master or con- troller flash unit. (>>> Remote operation)
Stroboscope mode
Manual flash mode for flash sequences with a selectable intensity, frequency, and number of flashes,
e.g. for special effect photos and motion studies.
Swivel reflector
Can be tilted horizontally and vertically for indirect flash. Can be tilted vertically for indi- rect flash.
T 
TTL flash control
While taking the photograph, the flash light is measured through the lens (TTL = through the lens) by
a sensor in the camera. The light output of the flash unit is terminated as soon as the subject is correctly exposed.
TTL
Reduces too high subject contrast (e.g. to brighten dark shadowy
areas in bright sunshine).
U
USB
Interface for firmware updates via the Internet.
W 
The flash unit can be reactivat-
ed by actuating the shutter re- lease if the flash is in
(>>> Automatic unit
Increases the light angle of the flash unit. Depending on the type of flash unit, the
ment is either integrated or attachable as an accessory.
Z 
Zoom size
Automatic adaptation of the dis- 
play of the reflector position of the flash unit to the
digital cameras.
