camera’s viewfinder.
4.2 Multi-zone flash exposure metering (preflash metering)
For system-induced reasons only possible with Minolta Dimage 5,
Dimage 7 and 7i! Multi-zone flash exposure metering (preflash me-
tering) is a modern variant of TTL flash operation. The cameras do not
permit standard TTL flash operation without preflash.
When the camera’s shutter release is pressed for picture shooting a preflash
is fired to measure the subject’s reflection. With the aid of its exposure system
and the 14-segment honeycomb pattern multi-zone metering, the camera’s
electronics captures the light reflected by the subject and determines the opti-
mal weighting for the 4 segments of flash exposure metering on the basis of
the measured light distribution and the information given by the AF system.
The subsequent main flash and the consequent exposure are performed
according to the results obtained by preflash metering.
The mecablitz must be set to TTL mode. Multi-zone flash exposure metering is
not specifically set or displayed on the mecablitz. For the setting procedure of
multi-zone flash metering on the camera and other details please refer to the
camera manual.
4.3 ADI flash control (Advanced Distance Integration)
For system-induced reasons, only possible with Dimage 5, 7 and 7i!
ADI flash control is a modern variant of TTL flash operation. The ca-
meras do not permit standard TTL flash operation without preflash.
ADI flash control is a multi-zone flash metering system (preflash metering)
expanded by additional guide number control.
The mecablitz must be set to TTL mode. ADI flash control is not specifically
displayed on the mecablitz. Please refer to the camera manual for the setting
procedure of ADI flash control and other details.

4.4 Manual flash mode
Various cameras automatically switch the mecablitz to TTL flash mode
when in Program “P” or in one of the Subject Program Modes. Manual
flash operation is then no longer possible. There is no correct exposure
confirmation given on the mecablitz LC display in the manual flash mode!
Set „Av“ aperture priority or the „M“ or „X“ manual modes on the camera.
Select the aperture and shutter speed (with „M“) on the camera according to
the given photographic situation (see the camera’s operating instructions).
4.4.1 Manual flash mode M with full light output
In this mode the mecablitz always fires uncontrolled flashes at full light out-
put. Adaptation to the given photographic situation is only by adjusting the
aperture setting on the camera accordingly. The mecablitz LC display will
indicate the flash-to-subject distance that has to be maintained for a correct
exposure (see also 5.4.2).
Setting procedure for the manual flash mode M
• Turn on the mecablitz by its main switch.
• Continue depressing the „Mode“ key until „M“ flashes on the LC display.
• The setting becomes immediately effective. The LC display is returned to its
normal state after approx. 5 sec.
4.4.2 Manual flash mode MLo with partial light output
In this mode the flash unit always fires uncontrolled flashes at 1/8th (Low) of
full light output. Adaptation to the photographic situation is by selecting a
corresponding aperture setting on the camera. The mecablitz LC display will
indicate the flash-to-subject distance that must be maintained for correct
exposure (see also 5.4.2).
Setting procedure for the manual flash mode MLo
• Turn on the mecablitz by its main switch.
• Continue depressing the „Mode“ key until „MLo“ flashes on the LC display.
• The setting becomes immediately effective. The LC display is returned to its
normal state after approx. 5 sec.
