Metz – always rst class.
Acoustic status notication (BEEP)
Additional acoustic status notications
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 multizone
AF measurement flash, also supports
decentralised AF sensors.
Automatic unit shut-o
During extended breaks from photographing,
the flash unit switches automatically to an
energy saving standby mode to prevent the
power source from discharging (Auto-O).
The wake-up function (>>> Wake-Up function)
reactivates the flash unit e.g. by lightly
depressing the camera shutter.
Automatic flash mode
A photo sensor integrated in the flash unit
measures the flash exposure of the subject
during photographing, and automatically
terminates the light output as soon as the
subject is correctly exposed.
Correct exposure display
The correct exposure display o.k., appears on
the flash unit aer photographing if the
subject in automatic or TTL flash mode is
correctly lit.
Dot matrix display with so keys
Individual adaptation of the display on the
camera 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-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 number of the flash unit.
Extended zoom
With the motorised zoom mode the main
reflector illuminates the subject more than
necessary by one reflector position. Thereby
providing additional scattered light indoors
for a soer illumination of the subject.
Flash bracketing
Flash bracketing series with three shots of
dierent 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
sucient energy for the shot.
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 guide number also
depends on the shutter speed.
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 possible in high ambient light levels, for
example in order to limit the depth of eld in
portrait shots.
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.
Key function
Locking of operational controls. Protects
against unintentional overwriting.
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).
