7.12 Contrast
To facilitate subject and pictorial composition, the camera flash can be combi-
ned 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-
text, please read the notes in the camera's operating instructions.
The auto-focus measuring beam in the mecablitz cannot be used in the contrast
control mode.
Adjusting the setting
• Press the button repeatedly until "Select"
appears on the display.
• Use the and buttons to select "Contrast" in
the menu. The selected menu option is indicated by a
dark bar.
• Press the button and confirm the setting of the
special function.

• Use the and buttons to make the desired
settings. The setting is effective immediately..
– In the ON setting the contrast function is acti-
vated.
– In the OFF setting the contrast function is deac-
tivated.
• Press repeatedly to return the display to normal.
If the button is not pressed, the display will switch back to normal auto-
matically after approximately 5 seconds.
When the external flash unit (mecablitz) and
the integrated camera flash are flash-rea-
dy, is appears on the display of the
flash unit and the contrast function is activa-
ted when the shot is taken.
If either of the flash units is not flash-ready, does not appear on the display
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.
Most integrated camera flash units only light focal lengths up to 35mm (see the
camera's operating instructions). If working with a focal length shorter than
35mm, a flash symbol appears in the LC display of the camera or in the camera
viewfinder to warn you that the marginal illumination of the subject may not be
sufficient! For more details see your camera's operating instructions.
