6 TTL flash modes
6.1 Digital TTL flash modes
Depending on the camera system and the version of flash unit there are various digital TTL flash
control systems available:
Canon E-TTL II ;Nikon i-TTL ; Sony pre-flashTTL ; Olympus/Panasonic FourThirds- and Micro-
Four-Thirds TTL ; Fujifilm TTL.
In the digital TTL flash modes you can easily achieve very good results inflash photography.
The flash unit uses TTL measuring pre-flash technology:
When shooting, oneor two TTL pre-flashes will be fired first by the flash unit.
The light of the TTL pre-flashes does not contributeto the exposureof the image.
The flashlight of the TTL pre-flashes reflected by the subject is taken care ofby a sensor in the
camera. It measures reflected light through the lens (TTL).
In TTL modes, excellent flash exposure is straight-forward. In TTL mode, flash metering is taken
care of by a sensor in the camera. It measures reflected light through the lens (TTL).
The benefit of TTL flash modes is that all factors which could influence the exposure (filters,
changes to aperture and focal lengthfor zoom objectives, extensions for close-ups etc.) are
automatically taken intoaccount through flash light adjustment.
6.2 Automatic TTL fill-in flash mode
For most camera types,automatic TTL fill-in flash is activated in programmed auto mode "P"
and variable or subject programs in daylight conditions (see camera operating instructions).
With fill-in flash you can remove annoying shadows, and in back-lit shots a balanced exposure
can be achieved betweensubject and background. A computer-controlled measuring system on
the camera ensures appropriate combinations of shutter speed, working aperture and flash
output.

13

Ensure that the backlight source is not shining directly into the lens. This will
interfer
There is no adjustmentor display for automatic TTL fill-in flash on the flash unit in this
instance.
6.3 Manual flash exposure correction in TTL flash mode

This function has to be configured on the camera, see camera operating instructions.
The automatic flash in most cameras is set to 25% reflectance (average reflectance of flash
subject).
A dark background which absorbs a lot of light or a light background which is heavily reflective
(e.g. backlit shots)can cause the subject to be over or underexposed.
To compensate for the above effect, the flash output can be adjusted manually with the
correction value of the shot.
The correction value is based on the contrastbetween the subject and the background.
Hint:
A dark subject in front of a light background = positive correction value.
A light subject in front of a dark background = negative correction value.

Exposure correction through alteration of the lens aperture is not possible, as the
the altered aperture as the normal working one.

Manual flash exposure correction in TTL flash modes can only take place if
thecamera supports this feature (see camera's manual).
the TTLexposure correction on the camera after the shot.

exposure. This results in underexposure. Remove reflective objects or set a positive
correction value.
6.4 TTL Flash exposure memory FE
Several Nikon and Canon cameras have a flash exposure memory (FV memory). This is
supported by the flash unit in the Nikon i-TTL or in the Canon E-TTL II flash modes.
It can be used to define and store the exposure level for the subsequent shotbefore the shot is
actually taken.
This can be useful when, for example, the flash exposure has to be adjusted to specific details
that may notbe necessarily be identical with the main subject.
The function is activated on the camera, in some instances as an individual function. The
subject detail towhich the flash exposure is to be adjusted is sighted and broughtinto focus
with the AF sensor/metering window in the camera.

14
Pressing the camera's AE-L/AF-L button (Nikon) or FE button (Canon - the description may vary
from camera to camera; see camera operating manual) causes the flash unitto fire a test flash.
The stored metering value, for example "EL" or "FEL", is then displayed in the camera
viewfinder.
The camera uses the reflected light of the test flash to determine the light output required for
the subsequent exposure.
The actual main subject can then be AF sensor/metering
window. When the shutter release is pressed, the picture will be exposed with the previously
defined light output of the flash unit!

In Canon cameras the flash exposure memory FE is not supported during the green
fully-automatic programme, the Vari programme and the subject programmes!

7 Swivel reflector
Flash unit's motor zoom swivel reflector can illuminate lens focal lengths from 24 mm and up
(135 format).

By using the integrated wide-angle diffuser  this value is extended to 14 mm.
7.1 Auto zoom
The zoom positionof the swivel reflector is automatically adjusted to the lens focal length
when the flash unit is used with a camera that transmits the data related to the lens focal
length.

Automatic adjustment does not occur when the wide-angle diffuser is extended.

15
7.2 Wide-angle diffuser
With the integrated wide-angle diffuser, focal lengthsfrom 14 mm can be exposed (135 format).
Flip the wide-angle diffuser out of the swivel reflector as far as it goes
and let go. It will fold down automatically.
The main reflector will be guided to the required wide-angle position
automatically.

Automatic adjustment of the motor zoom main reflector does not occur when the
wide-angle diffuser is in use.
To set the wide-angle diffuser to 90° flip it up and slide it in completely.
7.3 Mecabounce diffuser
The mecabouncediffuser (included in thebox) can be attached to the front of the motor zoom
main reflector.
With this diffuser, soft lighting can be achieved in a very simple manner. It gives your pictures a
marvellous soft appearance. Skin tones are captured more faithfully. Themaximum working
range is reduced by about half in conformity with the loss of light.
8 Flash techniques
8.1 Bounce flash
Bounce flash illuminates the subject more softly and reduces dense shadows. It also reduces
the drop in light from foreground to background that occurs for physical reasons.
The swivel reflector of the flash unit can be swiveled horizontally and tilted vertically for
bounce flash.
To avoid colour cast in your shots, the reflective surface should be colour-neutral or white.

When tilting the swivel reflector vertically, make sure that it is turned through an
angle that is wide enough to prevent direct light from falling on the subject.
For this reason the reflector should be tilted at least as far as the 60° lock-in
position.

16
8.2 Bounce flash with a reflector card
The use of bounce flash with the integrated reflector card canbring out highlights in the eyes
of human subjects:

Tilt the reflector head upwards by 90°.

Pull the reflector card together withthe wide-angle diffuser from
above out of the reflector head and forwards.

Hold the reflector card and push the wide-angle diffuser back
into the reflector head.
9 Program flash mode
In the Program flash mode, some cameras mix the ambient light with the flashlight and
depending on the camera programming determine whether the flash is tobe used as the
main light sourceor for fill-in light purposes. The camera automatically selects the appropriate
shutter speed/aperture combination and controls the flash inTTL mode.
the camera.
10 Automatic AF auxiliary light
The automatic AF auxiliary light is activated in the flash unit by the camera when the ambient
lighting conditions become inadequate for automatic focusing.
A bright light is projected onto the subject, which the camera can use to focus. Depending on
vated AF sensor, the AF assist light has a range of approximately 2.5 m to 4 m
(with a standard 1.7/50 mm lens).
Parallax error between lens and AF auxiliary light limits the close-up range with the AF
measuring beam to approximately 0.6 m to 1 m.

To activate the automatic AF auxiliary light the camera has to
readiness. Various camera models support only the ca auxiliary
light. In this case, the automatic AF auxiliary light of the flash unit is not activated
(as in the case of mirrorless cameras, manual).
Low-speed zoom lenses can significantly curtail the range of the AF auxiliary light!
Various camerassupport the AF auxiliary light in the flash unit only with
sensor. If a peripheral AF sensor is selected, then the AF auxiliary light beam will not be
activated in the flash unit!

17
11 Flash synchronisation
11.1 Automatic flash sync-speed control
Depending on the camera modeland camera mode, the shutter speed is switched to flash
sync-
Shutter speeds cannot be set faster than the flash sync-speed, or theyare switched
automatically to the flash sync-speed. Various cameras have a sync-speed range, for example
manual). The sync-speed set by the camera
depends on the camera mode, the ambient light, and the focal length of the lens used.
Shutter speeds slower than the flash sync-speed can be set according to the camera modeand
the selected flash synchronisation (see 11.3and 11.4).

If a camera with a between-the-lens shutter (see 11.3) is used, flash sync-speed is
not controlled automatically.
As a result, the flash can be used at all shutter speeds. If you need the full light
output of the flash unit, you should not select a shutter speed that is any faster
than 1/125 sec.
11.2 Normal synchronisation
In normal synchronisation the flash unit istriggered at the
beginning of the shutter time (firstcurtain synchronisation).
Normal synchronisation is the standard mode on all cameras. It is
suitable for most flash shots.
The camera,depending on the mode being used, is switched to
the flash sync speed. Speeds between 1/30sec. and 1/125 sec.
are customary (see the ca manual).
11.3 Second curtain synchronisation (REAR)
Various cameras offer the option of second-curtain synchronisation (REAR), in which the flash
unit is not triggered until the end of the exposure time.
This is particularly advantageous when used with lower shutter
speeds (slower than 1/30 sec.) and moving subjects that have
their own source of light. With second-curtain synchronisation, a
moving light source will trail a light streak instead of building one
up ahead itself, as it does when the flash is synchronized with the
first shutter curtain.
In this way a "more natural" image of the photographic situation is produced! Depending on its
operating mode, the camera sets shutter speeds slower than its sync speed.
On various cameras the REAR function is not possible in certain operating modes (e.g., in

18
certain vari- or subject programs, or with red eye reduction). In these cases, the REAR mode
cannot be selected and/or is automatically cancelled or ignored (see camera’s manual).

The REAR mode is set on the camera (see camera’s manual).
11.4 Slow synchronisation (SLOW)
A slow exposure (SLOW) gives added prominence to the image background at lower ambient
light levels. This is achieved by adjusting the shutter speed to the ambient light. Accordingly,
shutter speeds that are slower than the flash sync speed (e.g., shutter speeds up to 30 sec.)
are automatically adjusted by the camera. Slow synchronisation is activated automatically on
some camera models in connection with certain camera programs (e.g., a night shot program,
etc.), or it can be set on the camera (see the camera’s manual). No settings are necessary on
the flash unit, nor is there any display for this mode.

Slow synchronisation SLOW is set on the camera (see camera’s manual)! Use a tripod
when shooting with slow shutter speeds to avoid blurred images!
12 Triggering control (auto-flash)
On various cameras the flash will not be fired when the prevailing light is sufficient for an
exposure. When the camera shutter release is depressed, no flash exposure is triggered.
In various cameras the triggering control only works in the full program mode or "P" program or
must be activated on the camera (see camera's manual).
13 Pre-flash function for red-eye reduction
The red-eye effectoccurs when the person being photographed is lookingfor more or less
straight into the camera, the ambient lighting is poor, and the flash unit is mounted close to
the camera. The flash unit then illuminates the interior of
Some camera models have a pre-flashfunction for reducingthe red-eye effect.
One or more pre-flashes induce the pupils to contract more, thereby reducing the red-eye
effect.

Second curtain synchronisation (REAR) is not possible when the pre-flash function
is used.

14 Care and maintenance
Remove dust and grime witha soft dry cloth or silicon-treated cloth. Do not use cleaning agents
as these may damage the plastic parts.
14.1 Firmware updates
Flash unit firmware can be updated via the USB port and, withinthe technical framework,
adapted to the functionalityof future cameras.

Further information can be found on the Metz website:
www.metz-mecatech.de
14.2 Flash capacitor forming
The flash capacitor built into the flash unit undergoes physical change if the unit is not
switched on for a prolonged period. For this reason it is necessary to switch the unit on for
approximately 10 minutes at least onceevery three months. The power suppliedby the
batteries must be sufficient to cause the flash readiness indicator to light up no more than one
minute after the flash unit is switched on.
15 Troubleshooting
If the flash unit does not function as it should, switch it off for approx. 10 seconds via the
button ON/OFF  . Check the camera settings and that the flash unit connection foot is
fitted correctly in camera's accessory shoe.

Clean the visible electrical contacts in camera's hot shoe carefully with a soft cloth,
moistened with purealcohol (e.g. pureethanol orpure isopropanol).

Replace the batteries with new batteries or freshly charged rechargeable batteries. The
flash unit should function normally again once it is switched back on.If this is not the
case, contact your local dealer.
Below is a list of some of the problems that mayoccur when the flash unit is used. For each
item, possible causesand remedies for the problem are listed.

The AF auxiliary light of the flash unit is not activated.

The flash unit is not ready for firing.

The camera is not in"Single AF (S)" or "ONE SHOT" mode.

The camera supports only itsown internal AF auxiliary light, e.g. mostly with
mirrorless cameras, compact cameras and bridge cameras.

Various cameras support the AF auxiliary light in the flash unit only by
central AF sensor. If a peripheral AF sensor is selected, then the AF auxiliary light 
will not be activated in the flash unit.

20
Activate camera's central AF sensor, please.

The reflector position is not automatically adjusted to the current zoom position of
the lens.

The camera is not transmitting any digital data to the flash unit.

There is no exchange of data between the flash unit and the camera!

The camera is equippedwith a lens without CPU.

The built-in wide-angle diffuser is placed in front of the reflector.

Automatic switching to the flash sync-speed fails to occur.

The camera has a between-the-lens shutter (as do most compact cameras).
Switching to flash sync-speed is therefore unnecessary.

The camera operates with shutter speeds that are slower than the flash sync-speed.
Depending on the camera mode, there is no switch to flash sync-speed (see the

Fujifilm cameras do not support this function.

The shots have shadows in the bottom of the image.

Because of parallax error between lens and flash unit, close-up shots may not,
depending on the focal length at the bottom of the image, befully illuminated.
Turn the built-in wide-angle diffuser in front of the reflector.

The shots are too dark.

The subject is beyond the maximum distance range of the flash unit.
Note: Using bounce flash reduces the maximum distance range of the flash unit.

The subject contains very bright or highly reflective areas.The metering system of the
camera or flash unit is deceived as a result.
Set a positive manual flash exposure correction, e.g., +1 EV at the camera.

The shots are too bright.

When taking close-ups, make sure to preserve specific minimum illuminationranges
to avoid overexposure. The minimum distance from the subject should represent at
least 10% of the maximum range.
Maximum distance range = guide number (see table 1) ÷ aperture
Minimum distance to the motive = 0.1 x [guide number (see table 1) ÷ aperture]
