Metz Camera Flash Light manual ECH NI CA L Glossary

A ADI

Modern further development of the TTL flash control for Sony Alpha and Konica-Minolta cameras in

which, for example, the data for distance to the subject must be put into the flash exposure in addition.

AF measurement flash

An autofocus auxiliary light (AF measurement flash) integrated in the flash unit automatically supports

the central autofocus sensor of the camera in the event of low ambient light. For a multi-zone AF measurement flash, the decentralized AF sensors are supported in the process.

Automatic unit switch-off

During extended breaks from photographing, the flash unit is switched automatically to an energy-

saving standby state to prevent the power source from discharging (Auto-Off). Through the wake-up function, the flash unit is reactivated, for example when the shutter release is actuated.

Automatic flash mode

A photo sensor integrated in the flash unit measures the subject during photographing, and automatically

terminates the light output as soon as the subject is correctly exposed.

B Buzzer

Additional acoustic status mes- sages can be activated for flash readiness, flash exposure control as well

as warning tones.

C Correct exposure indication

The correct exposure indication OK is shown on the flash unit after the photograph if the subject in automatic or TTL flash mode was correctly exposed.

D D-TTL

Modern further development of the TTL flash control with measurement pre-flash technique for Nikon

and Fujifilm cameras.

3D and D-TTL-3D

For the 3D-TTL (Nikon) and D-TTL-3D flash control, additional data such as the distance to the subject,

for example, is taken into consideration in the flash exposure.

Dot matrix display with soft keys

Individual adaptation of the display on the camera system and the operating state for optimum and

self-explanatory operation of the flash unit via soft keys.

E E-TTL

Modern further development of the TTL flash control with measurement pre-flash technique for

Canon EOS and PowerShot cameras.

E-TTL II

For E-TTL-II, additional data is taken into consideration during flash exposure such as the distance to the

subject and the guide number of the flash unit, for example.

Extended zoom

With Motor Zoom mode, the main reflector illuminates the subject more than necessary by one reflector position.

As a result, the additional dispersed light provides softer illumination of the subject.

F Flash bracketing

Flash bracketing series with three photos of different flash ex- posure: minus correction value, no correc-

tion value, and plus correction value.

Flash readiness indication

The flash readiness indication illuminates when there is enough energy in the flash capacitor of the flash unit.

G Guide number (GN)

The guide number is the code number for the light output of a flash unit. It is dependent on the set light sen- sitivity ISO and (for zoom reflectors) on the reflector position, as well as on any reflector attachments that may be in use (e.g. wide- angle or telephoto lens cover). For high speed synchronization (HSS), the guide number is dependent on the shutter speed as well.

H HSS – high speed synchronization

In high speed synchronization (HSS), you can flash with expo- sure times that are shorter than the flash

sync time of the camera. As a result, flash photos with wide aperture openings are possible for high ambient light levels, for example to limit the depth of field in portrait shots.

I i-TTL

Modern further development of the TTL flash control with measure- ment pre-flash technique for Nikon and

Fujifilm cameras.

i-TTL-BL

For the i-TTL BL flash control, ad- ditional data such as the dis- tance to the subject, for example, is taken

into consideration in the flash exposure.

K Key function

Locking of the operating ele- ments. Protects against uninten-

tional changes.

L LCD / LED display

Provides information on the flash modes and settings being used.
