Metz – always rst class.
A
Acoustic status notication (BEEP)
Additional acoustic status notications can be
activated for flash readiness, flash exposure
control and alerts.
AF flash metering
An autofocus auxiliary light (AF measurement
flash) integrated in the flash unit automatically
supports the central autofocus sensor of the
camera in low ambient light conditions. A multi-
zone AF measurement flash, also supports de-
centralised AF sensors.
Automatic unit shut-o
During extended breaks from photographing,
the flash unit switches automatically to an ener-
gy saving standby mode to prevent the power
source from discharging (Auto-O).
The wake-up function (>>> Wake-Up function) re-
activates the flash unit e.g. by lightly depressing
the camera shutter.
Automatic flash mode
A photo sensor integrated in the flash unit mea-
sures the flash exposure of the subject during
photographing, and automatically terminates
the light output as soon as the subject is cor-
rectly exposed.
C
Correct exposure display
The correct exposure display o.k., appears on
the flash unit aer photographing if the subject
in automatic or TTL flash mode is correctly lit.
D
Dot matrix display with so keys
Individual adaptation of the display on the came-
ra system and the operating status for optimum
and self-explanatory operation of the flash unit
via so keys.
D-TTL
Further development of the TTL flash control
with metering pre-flash technology for Nikon
cameras.
3D and D-TTL 3D
With the 3D-TTL (Nikon) and D-TTL 3D flash
control, additional data such as the distance to
the subject is taken into account during flash
exposure.
E
E-TTL
Innovative advancement of TTL flash control
with pre-flash metering technology for Canon
EOS and PowerShot cameras.
E-TTL II
With the E-TTL II flash control, additional data is
taken into account during flash exposure, such
as the distance to the subject and the guide num-
ber of the flash unit.
Extended zoom
With the motorised zoom mode the main reflec-
tor illuminates the subject more than necessary
by one reflector position. Thereby providing
additional scattered light indoors for a soer
illumination of the subject.
F
Flash bracketing
Flash bracketing series with three shots of die-
rent flash exposure: minus correction value, no
correction value, and plus correction value.
Flash readiness display
The flash readiness display lights up when the
flash unit’s flash capacitator possesses suci-
ent energy for the shot.
G
Guide number
The guide number is the code number for the
light output of a flash unit. It is dependent upon
the preset ISO light sensitivity and (with zoom
reflectors) on the position of the reflector, as well
as on the potential use of reflector attachments
(e.g. accessory wide-angle or telephoto lens).
With high speed synchronisation (HSS) the gui-
de number also depends on the shutter speed.
H
HSS – high speed synchronisation
In high speed synchronisation (HSS), you can
flash with shutter speeds that are shorter than
the flash sync time of the camera. As a result,
flash photos with wide focal aperture are pos-
sible in high ambient light levels, for example in
order to limit the depth of eld in portrait shots.
I
i-TTL
Innovative advancement of the TTL flash control
with metering pre-flash technology for Nikon
cameras.
i-TTL-BL
With the i-TTL-BL flash control, additional data
such as the distance to the subject is taken into
account by the flash lighting.
K
Key function
Locking of operational controls. Protects against
unintentional overwriting.
L
LCD display
Provides information about the operating modes
and settings being used. (>>> Dot matrix display)
Learning mode
The flash unit is capable of recognising the
camera’s pre-flash technology and in turn of
circumventing pre-flash technology. The flash is
therefore only activated as the main flash when
taking photographs (subject to camera).
