6.1 Bounce flash with secondary reflector

(not possible with 70 MZ-4)
The secondary reflector produces frontal fill-in light when the flash is
bounced.
Use of the secondary reflector is only meaningful in bounce flash pho-
tography.
The secondary reflector is switched on and off with switch
symbol on the LC display of the mecablitz merely indicates that the main re-
flector has not yet been turned.
Activation of the secondary reflector assigns approx. 85 % of the emitted
light to the main reflector and 15 % to the secondary reflector. These %-va-
lues can differ somewhat when shooting with partial light output and secon-
dary reflector.
Light output can be reduced to 1/2 or 1/4 with switch
output of the secondary reflector is too high.
The sub-modes stroboscope and 3D multi-sensor are not possible in
conjunction with the secondary reflector.

6.2 Bounce flash in automatic and TTL flash mode

Prior to picture taking it is advisable to check whether sufficient light is avail-
able for the selected aperture. For this purpose proceed in the manner de-
scribed in Chapter „10. Correct exposure indication".

6.3 Bounce flash in manual flash mode

The required aperture on the camera in the manual flash mode is best esta-
blished with a flash meter. If a flash meter is not available, observe the fol-
lowing rule of thumb
Camera aperture = — — — — — — — — — — — — — — — — —

to establish a guide value for the aperture that can then be varied by ±1 f-stop
for the shot to be taken.

7. Remote mode

General
In the remote mode, additional flash units (slaves) are fired under the cord-
less control of the master flash unit (controller) mounted on the camera. The
when the light
controller extends TTL automatic exposure control to all slaves.
The Metz TTL remote mode enables joint cordless TTL flash control of several
flash units of the types 54 MZ-.., 34 CS-2, 40 MZ-.., 50 MZ-5 and 70 MZ-4.
For this mode all additional 54 MZ-... flash units (slaves) must be fitted with
an SCA 3083 slave adapter (optional extra), and all 40 MZ-.. slaves with the
SCA 3080 or 3082 slave adapter. The slave flash units can be mounted on
the foot supplied with the slave adapter or on a tripod.
The slave flash units 34 CS-2, 50 MZ-5 Slave and 70 MZ-5 do not require a
slave adapter.
The LC display of the mecablitz does not indicate the maximum flash
range when in remote mode. The secondary reflector of the mecablitz
must be switched off!
To ensure that two TTL remote systems in neighbouring rooms do not interfere
with each other, two different addresses - Ad1 and Ad 2 - can be selected on
the controller (master) and the slave unit.
