- when „S On" is displayed the Zoom-Size function is activated.
- when „S Off" is displayed the Zoom-Size function is deactivated.
The setting takes effect immediately. After about 5 seconds the display stops flas-
hing and the setting is saved automatically. „S" is shown in the display following
activation of the Zoom-Size function.

9.10 Contrast (CC)

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-
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
• Lightly touch the shutter release, so that the data transfer between flash unit
and camera occurs.
• Press key combination "Select" repeatedly until "CC" (=contrast control) starts
flashing.
• Set as desired, using the keys ( + ) and ( - ).
- Contrast control is active "CC On" is on the indicator.
- Contrast control is NOT active "CC Off"„ is on the indicator.
The setting is immediately effective. After approx. 5 seconds the display stops
flashing and the setting is automatically saved. After activating contrast control
"P TTL" will appear in the display.
Contrast control cannot be activated if the high-speed synchronisation FP
or HSS is set at the flash unit (see 7.3)!
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 11.3) or the High-
Speed flash mode P-TTL-HSS (see 7.3) 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.

10 Flash techniques

10.1 Bounce flash

Bounce flash illuminates the subject more softly and reduces dense shadows. It
also reduces the drop in light from foreground to background that occurs for
physical reasons.
The main reflector of the flash unit can be swivelled horizontally and tilted
vertically for bounce flash. To avoid colour cast in your shots, the reflective surfa-
ce should be colour-neutral or white.
When tilting the main reflector
through an angle that is wide enough to prevent direct light from falling
on the subject. For this reason the reflector should be tilted at least as far
as the 60° lock-in position. Flash ranges do not appear on the display
when the main reflector is turned! When the reflector head is tilted, the
vertically, make sure that it is turned
