Foreword
Dear Customer,
We thank you for your confidence in our meca-
blitz MB 34 AF-3C.
The MB 34 AF-3C flashgun has been especially
designed for Canon EOS system cameras.
IMPORTANT: Never mount the flashgun in the
accessory shoe of any other system camera,
otherwise the flashgun’s foot or the camera’s
accessory shoe can be destroyed! The dedica-
ted contacts in the foot of the MB 34 AF-3C
only support the controlling commands of
Canon EOS system cameras.
The following pages give details for the correct
operation of the mecablitz flashgun and summarize
its fields of application.
Please read these operating instructions carefully,
even if, at first sight, some points may not appear
to be of interest. Our design work placed
particular
value on ensuring that operation of the mecablitz is
as simple
as possible, but it should be noted that
the system cameras for which the flashgun is
intended offer a great diversity of capabilities.
We wish you much pleasure with your new Metz
flashgun in conjunction
with a Canon EOS system
camera to light up the darkest points, and for
creative flash lighting.

1. Safety instructions
•NEVER fire a flash in the immediate vicinity of
the eyes! Flash fired directly in front of the eyes
ofapersonoranimalcandamagetheretinaand
leadto severevisual disorders- evenblindness!
• Spent batteries should be immediately remo-
ved. Chemicals leaking out of spent batteries
will damage the flashgun.
• Do not short-circuit batteries! DANGER OF
EXPLOSION!
• Batteries should not be exposed to excessive
heat, for instance sunshine, fire and the like!
•NEVER throw spent batteries in a fire!
• Do not expose the flashgun to dripping or
splashing water!
• Protect the flashgun against excessive heat and
high humidity levels! Do not keep the flashgun
in the glove compartment of a car!
• In the event of flash shots with full light output
observe an interval of at least 3 minutes after a
series of 20 flashes. This will protect the flash-
gun against overload.
•
NEVER place material that is impervious to light
in front of, or directly
on, the reflector screen.
The reflector screen must be perfectly clean
when a flash is fired. The high energy of the
flash light will burn the material or damage the
screen if this is not observed!
•NEVER dismantle the flashgun! DANGER: HIGH
VOLTAGE! There are
no components inside the
flashgun that can be repaired by a layperson.
Disposal of batteries
Do not dispose of spent batteries with domestic
rubbish.
Please return spent batteries to collecting points
should they exist in your country!

2. Preparing the mecablitz for use
2.1 Power supply
The flashgun can only be operated with 2 CR2-
type lithium batteries. This type of battery can be
stored for many years with practically no loss of
energy, thus making it ideal for occasional ama-
teur flash photography.
Batteries have become discharged or spent
when recycling takes more than 60 seconds.
The batteries should be removed from the
mecablitz if the flashgun is not going to be
used for a prolonged period.
2.2 Loading and exchanging batteries
• Turn off the flashgun with the main switch.
•Press the unlocking catch, slide the battery
compartment lid to the right and fold open (see
fig. 1).
•Insert the batteries according to the indicated
battery symbols.
The supplied lithium batteries are expendables
and, as such, are not subject to our warranty pro-
visions.
After the batteries have been inserted, fold down
the battery compartment lid, and push to the left
until it engages audible with the unlocking catch.

2. Preparing the mecablitz for use
When loading the batteries ensure correct
polarity. Incorrectly loaded batteries can dest-
roy the flashgun! All batteries must be of the
same make and have the same charge level.
Exhausted batteries must not be thrown into
the dustbin! Contribute to the protection of
the environment and discard exhausted bat-
teries at the appropriate disposal points.
2.3 Automatic flashgun switch-off
To avoid accidental battery discharge the flashgun
automatically switches itself off to save power
approximately 8 minutes after
- the flashgun was switched on
- the last flash was fired
- tripping the camera release, or
- switching on the camera light metering system.
The green flash-ready indicator is turned off.
To turn on the mecablitz again switch the main
switch OFF and then ON. The flashgun should
always be turned off if it is not being used.
2.4 Mounting/Removing the flashgun
• Turn off the mecablitz.
• Press the unlocking catch at the back of the
mecablitz (see fig. 2).
• Slide the mounting foot into the camera’s moun-
ting shoe.
•
Always turn off the flashgun before it is removed.
• Press the unlocking catch at the back of the
mecablitz (fig. 2) and withdraw from the camera.

3. Setting the mecablitz into operation
3.1 Preconditions
The mecablitz must only be used with TTL
flash controlled cameras!
The sensor of TTL flash controlled cameras
measures the light reaching the film through
the camera lens and instantly cuts out the
flash when the film has been correctly expo-
sed. Please refer to the camera’s operating
instructions to find out whether your camera
features this function.
A full-power flash is fired if the camera does
not feature TTL flash control!
In other words: Without TTL flash control, the
mecablitz fires an unmeasured flash at maximum
output.
If there is a flashgun integrated in the camera it
must be switched off or completely folded
down when the mecablitz is used.

3.2 Switching the flashgun on and off
Set the main switch in the ON position to turn on
the flashgun. The green flash-ready indicator
lights up to indicate flash readiness.
Set the main switch in the OFF position to turn off
the flashgun.

4. Flashgun instructions to the camera
The mecablitz transmits different signals and
messages to the camera when it is connected to
the camera and is switched on.
4.1 Flash-ready indication
The green light on the mecablitz illuminates
when the flash capacitor is fully primed, thereby
indicating flash readiness. This means that flash
can be used for the next exposure. The flash rea-
diness signal is transmitted to the camera where it
is indicated by a corresponding display in the
camera’s viewfinder. On some cameras (depen-
ding on the operating mode and camera model)
the shutter is automatically changed to flash sync
speed when flash readiness is reached. The flash
willnot befiredif theshutteris releasedbefore the
flashready light illuminateswith the resultthat the
exposure may be incorrect if the camera control
circuit has already changed over to flash sync
speed. Please refer to the camera’s operating
instructions for further details.
4.2 Automatic flash sync speed control
When the flash unit is on, the camera will automa-
tically switch it to flash sync speed from any ope-
rating mode selected. The sync speed depends on
the camera model and usually ranges between
1/30 sec. and 1/250 sec. For details please refer
to the camera’s instructions for use.
Some camera models will, when the flash unit is on,
switch it to flash sync speed as soon as program
mode „P“ or full-auto mode is selected. Speeds
faster than the flash sync speed cannot be set.
4.3 Correct-exposure indication (see fig. 4)
The red correct exposure light briefly illuminates
when flash exposure was correct. At the same
time the mecablitz sends an o.k. signal to the
camera for display in the viewfinder. Please refer
to the camera’s operating instructions for further
details.

5. TTL flash control
The mecablitz receives its information exclusively
from the connected TTL-controlled camera.
Exposure measurement in TTL mode (TTL =
through-the-lens) is completed by the camera’s
sensor. This sensor measures the light reaching
the film through the camera lens. An electronic
control circuit within the camera transmits a stop
signal to the flashgun as soon as the film has been
exposed by the correct amount of light; the flash is
then instantly cut out. The advantage of the TTL
mode is that all factors influencing the exposure of
the film (such as filters, change of aperture or
variable aperture zooms) are taken into account.
You need not worry about adjustment of the light
output. The camera’s electronic system automati-
cally defines the required amount of light. You can
also utilize various metering facilities
(e.g. spot ,
matrix or centre-weighted overall readings)
offered
by some cameras.
The Table on page 37 gives the maximum range
for the selected aperture. The minimum lighting
distance is approx. 15% of the maximum thres-
hold range.
If the actual distance is shorter than the
minimum lighting distance, then this may
result in overexposure.
Astrip offilmmust beloadedin thecamera iftests
are to be conducted in TTL flash mode.
The effective flash range can only be checked by
the correct-exposure display (o.k.) if the flash is
triggered by the camera and not with the manual
release on the flashgun!
