range. The subject should be located in the middle third of the indicated ran-
ge to give the electronic circuit leeway for compensation.
We recommend the camera mode aperture priority (A, Av) or manual (M).
Automatic setting of the ISO value and aperture
The aperture and ISO sensitivity of the camera can be automatically set on
the flash unit when the latter is operated with an adapter from the SCA 3002
system:
The automatic setting range for ISO extends from ISO 6 to ISO 6400.
The automatic setting range for the aperature extends from f/1.0 to
f/45 (at ISO 100 / 21°), including all the in-between values.
• Equip the flash unit with the connecting cable SCA 3045 3) and appropria-
te adapter from the SCA 3002 system and connect to the camera.
• On the flash unit, set any auto working aperture with the setting mark for
aperture pre-selection ተ.
• Switch on the flash unit and the camera.
• Lightly touch the camera’s shutter release so that data can be exchanged
between the camera and the flash unit.
• Continue depressing the ”Mode” key ቭ until “A” and “ “appear on the
indicator window. When the camera’s shutter release is lightly touched the
flash unit automatically takes over the data for the aperture and ISO setting
from the camera. The values for auto working aperture and ISO manually
adjusted on the flash unit are irrelevant in this context.
For manual adjustment of the ISO and aperture (e.g. with fill-in flash)
continue depressing the “Mode” key
ቭ until only “A” is displayed on
the display window.
6.2 TTL flash mode
In TTL flash mode the camera’s sensor measures through-the-lens (TTL) the
light reflected by the subject. This means that light measurement also takes
mounted filters into account. When an adequate amount of light has been
reached the camera’s electronic circuit switches off the flash by way of the
SCA adapter.

Setting procedure
• Equip the flash unit with the connecting cable SCA 3045
3) and a suitable
adapter from the SCA 3002 system and connect to the camera. Adapters
of the SCA 300 system can be connected to the flash unit with the connec-
ting cable SCA 3045
3) or the connecting cable SCA 300A.
• Adjust TTL on the flash unit with the setting mark for aperture pre-selection
ተ.
• Switch on the flash unit and the camera. “TTL” is displayed on the indicator
window.
The maximum flash range can be read off directly from the aperture calcula-
tor under the f-stop when the ISO value of the camera or film has been
manually set on the flash unit. The shortest shooting distance is approx. 10%
of the maximum flash range. The subject should be located in the middle
third of the indicated range to give the electronic circuit leeway for compen-
sation.
The aperture or ISO value does not have to be set on the flash unit for
the TTL flash mode to function!
6.3 TTL flash mode with preflash
In TTL flash mode with preflash the reflective properties of the subject are
established with one or more preflashes prior to exposure and evaluated by
the camera’s electronic circuit. The distance data from the camera’s AF sys-
tem can be additionally taken into account. Light output control by the
camera’s electronic system is via an adapter from the SCA 3002 system. The
preflash mode is selected with the ‘”Mode” key
ቭ.
Many modern camera models, but particularly many digital cameras,
only support the TTL flash mode with preflash (e.g. Canon E-TTL,
Minolta ADI, Nikon D-TTL, Nikon iTTL etc.). These are further develop-
ments of the standard TTL flash mode which is not supported by these
cameras. For further details please refer to the camera’s operating
instructions.
