Pentax ZX-5N - Manual (Page 83)

When using the Three-Level Auto (red, green, and
yellotA/ settings) mode, the aperture value is adjusted
as shown in the table. When the flash is fully charged,
the shutter speed also varies within the shutter speed
range of 1/100 to a slower speed which does not
cause camera shake. The slowest shutter speed var­
ies according to the lens focal length. When a non­
autofocus
lens, the shutter speed will be set to
1/100 of second.

Notes on Pentax dedicated flash units
When the built-in flash is used in combination with a
Pentax dedicated flash unit, if the trailing-shutter-
curtain sync flash mode is set for the dedicated flash
unit, the built- in flash also operates in the trailing-
shutter-curtain flash sync. mode. Ensure that both flash
units are fully charged before releasing the shutter.
Contrast-Control-Sync Flash Photography
Using the AF330FTZ or AF500FTZ in combination with
the
built-in flash allows twin flash photography
(contrast-control-synch flash photography). This is
based on the difference between the amount of light
discharged from two units.
1. Put the AF500FTZ or AF330FTZ in the Contrast-
Control-Sync Flash Mode.
2. Ensure that both flash units are fully charged and
then shoot.
• The ratio of the amount of flash light is 1 (built-in
flash) : 2 (dedicated flash unit). When the
AF500FTZ or AF330FTZ is used off the camera, the
effect of contrast control is increased. Use an op­
tional "Hot Shoe Adapter F" (use two pieces for the
AF330FTZ) and "Extension Cord 5P" to connect the
dedicated flash unit to the camera. Do not combine
an accessory with a different number of contacts
such as a "Hot Shoe Grip" as a malfunction may
occur.
• In the Contrast-Control-Sync Flash Mode, the top
flash sync speed is 1/60 of second.
Multi-burst flash with the Pentax dedicated flash
When discharging more than 2 Pentax dedicated
flashes, make sure that they are of the same type, com­
bine the Type B with Type C or Type D with Type E.
(refer to the overview of Flash Function on page 80).
The Built-in flash can be operated with any type of
Pentax TTL dedicated flash unit.
