1. Safety instructions  
NEVER fire a flash in the immediate vicinity of  
• 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.  
the eyes! Flash fired directly in front of the eyes  
of a person or animal can damage the retina and  
lead to severe visual disorders - even blindness!  
Spent batteries should be immediately remo-  
ved. Chemicals leaking out of spent batteries  
will damage the flashgun.  
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!  
Do not short-circuit batteries! DANGER OF  
EXPLOSION!  
Batteries should not be exposed to excessive  
heat, for instance sunshine, fire and the like!  
NEVER dismantle the flashgun! DANGER: HIGH  
VOLTAGE! There are no components inside the  
flashgun that can be repaired by a layperson.  
NEVER throw spent batteries in a fire!  
Do not expose the flashgun to dripping or  
splashing water!  
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!  
Protect the flashgun against excessive heat and  
high humidity levels! Do not keep the flashgun  
in the glove compartment of a car!

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.  
Fig. 1: Unlocking and exchanging batteries  
2.2 Loading and exchanging batteries  
The supplied lithium batteries are expendables  
and, as such, are not subject to our warranty pro-  
visions.  
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).  
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.  
• Insert the batteries according to the indicated  
battery symbols.

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.  
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.  
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 ashgun should  
always be turned off if it is not being used.

3. Setting the mecablitz into operation  
3.1 Preconditions  
The mecablitz must only be used with TTL  
ash 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 cameras operating  
instructions to find out whether your camera  
features this function.

Fig. 3: Switching the flashgun on and off  
A full-power flash is fired if the camera does  
not feature TTL ash control!  
3.2 Switching the flashgun on and off  
In other words: Without TTL flash control, the  
mecablitz fires an unmeasured flash at maximum  
output.  
Set the main switch in the ON position to turn on  
the flashgun. The green flash-ready indicator  
lights up to indicate flash readiness.  
If there is a flashgun integrated in the camera it  
must be switched off or completely folded  
down when the mecablitz is used.  
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  
4.2 Automatic flash sync speed control  
messages to the camera when it is connected to  
the camera and is switched on.  
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 cameras instructions for use.  
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  
cameras 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  
will not be fired if the shutter is released before the  
flash ready light illuminates with the result that the  
exposure may be incorrect if the camera control  
circuit has already changed over to flash sync  
speed. Please refer to the cameras operating  
instructions for further details.  
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 cameras operating instructions for further  
details.

5. TTL ash control  
The mecablitz receives its information exclusively  
from the connected TTL-controlled camera.  
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.  
Exposure measurement in TTL mode (TTL =  
through-the-lens) is completed by the cameras  
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 cameras 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.  
If the actual distance is shorter than the  
minimum lighting distance, then this may  
result in overexposure.  
A strip of film must be loaded in the camera if tests  
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!

5.1 E-TTL ash control  
E-TTL ash control is only possible with cameras  
featuring this function. E-TTL ash control is auto-  
matically set on the flash unit.  
In the E-TTL ash control mode, a pre-ash is fired  
to establish the reflective characteristics of the  
subject just before the actual shot is taken. A par-  
tial light output level is transmitted and adjusted  
on the flash unit as a result of this measurement.  
The aperture and shutter speed to be used are  
established by the camera according to the  
ambient light before the actual exposure, and are  
automatically adjusted in the program modes.  
The red E-TTL“ indicator lights up on the mecablitz.  
Flash exposure storage  
This feature permits the flash exposure of an off-  
center subject to be metered and stored. It is only  
possible in the cameras creative modes and is  
performed by way of the cameras memory but-  
ton.

6. Flash synchronisation  
Different modes of flash synchronisation are pos-  
sible, depending on the camera model. Please  
refer to the cameras operating instructions to find  
out how the individual modes of synchronisation  
are set on the camera.  
6.1 Normal synchronisation  
First curtain  
Second curtain  
This mode is available with all TTL cameras, and it  
is suitable for most flash shots. With normal  
synchronisation, switching to the camera’s flash  
sync shutter speed is automatic. The shutter speed  
may vary from 1/30th and 1/250th seconds,  
depending on the camera model. Please refer to  
the cameras operating instructions for further  
details.  
With normal synchronisation, the flash is fired pre-  
cisely after the opening of the first shutter curtain.  
When using slow shutter speeds, and with moving  
objects, this would result in an unnatural rendition  
of light traces. With second curtain or rear curtain  
synchronisation, the flash is fired as the exposure  
is ending, just before the second curtain covers  
the film again. This makes the light trail behind the  
moving objects instead of appearing in front of  
them, and renders a more natural looking picture.  
6.2 Second curtain synchronisation (REAR)  
Some cameras offer the facility of second shutter  
curtain synchronisation.

7. Flash in the individual camera modes  
7.1 Use of ash in the program modes  
Program shift:  
Program shift (shutter speed/aperture combina-  
tion) in auto program mode cannot be performed  
when the flashgun is switched on.  
TTL-controlled flash shots can be made in all expo-  
sure and auto program modes. Once the mecablitz  
is attached to the camera and switched on, it auto-  
matically operates with TTL flash control in auto

7.2 Special functions not supported by flash  
Depth of eld (DEP):  
The depth of field auto mode is not operative  
when the flashgun is switched on. Exposure is  
then completed as in the auto program mode.  
Soft focusing (SF):  
The flash is only fired for the first exposure in the  
soft focusing mode. This means that a soft focu-  
sing effect may not be achieved!

8. Autofocus measuring flash  
The integrated AF red-light beam of the mecablitz  
supports the automatic focusing of autofocus TTL  
cameras. When the prevailing light is insufficient  
for automatic focusing, the mecablitz will project a  
pattern of red vertical stripes onto the subject as  
soon as the cameras release is lightly touched.  
The cameras autofocus system then focuses the  
picture by this striped pattern.  
AF red-light beam  
Notes:  
When the cameras autofocus system is on, the  
electronic circuit will automatically activate the  
autofocus measuring flash whenever the  
prevailing light is insufficient for the exposure.  
Fig. 5: AF red-light beam  
The range of the autofocus measuring flash  
depends on the speed of the lens (maximum  
aperture)! With an f/1.8 standard lens of 50 mm  
focal length, the range is approx. 6-10 m (depen-  
ding on the sensitivity of the camera’s AF sen-  
sor).  
The autofocus measuring flash cannot be activa-  
ted in every operating or autofocusing mode of the  
camera. It only supports focusing priority (one-  
shot AF: see cameras operating instructions). Use  
of the autofocus measuring flash is not possible  
with shutter release priority (Al Servo AF).

8. Autofocus measuring flash  
9. Flash techniques and flash functions  
Depending on the camera type, either the AF  
illuminator of the camera or that of the flashgun  
will be activated whenever the autofocus mea-  
suring facility becomes necessary.  
Only the central AF sensor is supported  
Low-speed lenses, e.g. with an aperture of  
f/5.6 or f/8 (such as zoom lenses), signifi-  
cantly restrict the range of the autofocus  
measuring flash!  
Fig. 6: Fill-in flash in daylight (left without, right with fill-in flash)  
9.1 Automatic fill-in flash  
Some cameras offer the facility of activating auto-  
matic fill-in flash control or automatically trigger a  
fill-in flash. Fill-in flash will soften harsh shadows  
and diminish the contrast, thereby producing a more  
balanced exposure when shooting against the light.  
The cameras computer-controlled measuring  
system automatically selects the shutter speed,  
working aperture and light output in such a manner  
that both the main subject in the foreground as well  
as the background are uniformly exposed.  
Please refer to the cameras operating instructions.

10. Lighting and attachments  
guiding edge  
Your mecablitz provides full and even illumination  
of normal 24 x 36 mm negatives when using len-  
ses of 35 mm focal length and longer.  
A wide-angle diffuser is supplied with the flash-  
gun to increase the coverage if you wish to use a  
28 mm wide-angle lens.  
A telephoto attachment (identified with a T) is  
included for telephoto lenses of 85 mm focal length.

11. Care and maintenance - Troubleshooting  
Remove grime and dust with a soft, dry cloth. Do  
not use cleaning agents as these could damage  
the plastic parts.  
Forming the flash capacitor  
The flash capacitor incorporated in the flashgun  
undergoes a physical change when the flashgun is  
not switched on for prolonged periods. For this  
reason it is necessary to switch on the flashgun for  
approx. 10 minutes every 3 months and to fire a  
few flashes The batteries must supply sufficient  
power to light up the flash-ready light within one  
minute after the flashgun was switched on.  
Fig. 8: Manually firing button  
Troubleshooting:  
Manual ring button  
If the flashgun does not work as it should in the  
individual modes, then proceed as follows:  
An uncontrolled flash can be fired with the manual  
firing button (see fig. 8).  
Switch off the flashgun with the main switch.  
Remove the rechargeable or dry-cell batteries  
for a brief period, and then load them again.
