7.12 Contrast
To facilitate subject and pictorial composition, the camera flash can be combined
with an external flash unit (mecablitz) to perform so-called contrast control when
in TTL- or P-TTL flash mode. Here the camera flash provides 1/3 of the required
flash power and the external flash unit provides the remaining 2/3.
Please observe the maximum possible flash range (guide number) of both
flash units to ensure the correct operation of the contrast control!
The benefits of contrast control can, however, only be optimally exploited if the
external flash unit is set up at a reasonable distance from the built-in camera
flash. To do so, the following original Pentax accessories are available:

The "sync cable F 5P", combined with the "adapter foot F" (to hold the external
flash unit) and "adapter foot FG" (for the connection to the camera). In this con-

control mode.

is appears on the display of the flash unit and the contrast func-
tion is activated when the shot is taken.
If either of the flash units is not flash-ready,
and the contrast function is not activated. The shot is then taken using normal
synchronisation (1st shutter curtain synchronisation).
The contrast function is not activated if the camera flash has not been
engaged or the TTL or P-TTL flash mode has not been selected on the flash
unit. Synchronisation is with the 1st shutter curtain. The contrast function
is automatically cancelled as soon as REAR mode (see 16.2) or the High-
Speed flash mode P-TTL-HSS (see 16.4) are activated.
