Common Functions of TTL Auto Flash and Programmed
Auto Flash Modes
In the Metered Manual mode, slow-shutter-speed
synchronization can be used by selecting a shutter speed
between 1/60 second and one second. The shutter speed
can be selected by turning the select dial to the left or
right until the desired speed appears on the LCD panel.
• When the shutter speed is set between 1/2000 second
and 1/125 second, it is switched to the flash-sync speed
of 1/100 second when the flash is fully charged.
Flash Confirmation Signal ( ^ )
When a proper flash exposure is made in the TTL Auto
Flash or Programmed Auto Flash mode while the camera
is set in an AE or Metered Manual mode, the flash-ready
indicator [ H in the viewfinder confirms it right after
the discharge, either by disappearing for a moment and
coming back on again or by blinking,
* The AF200SA does not have the flash confirmation
signal function.
Precautions for Using Pentax Dedicated Flash Units
• When using a flash unit in the manual sync (MS) or
manual IM) mode, select an f-number using the lens
aperture ring. If the ring is set at the "A" position,
a correct exposure cannot be made. The functions in
the MS and M modes may vary depending on the type of
flash used, so check the operating manual of the flash
in use for details.
• Multi-flash photography in the TTL Auto Flash or
Programmed Auto Flash mode can be done by combining
the RTF with the Pentax dedicated flash. In this case, the
dedicated flash attached to the camera's hot shoe has
a priority for different functions over the RTF. When
combining conventional dedicated flash units, use the
lens aperture ring to select the aperture. Be sure to check
the flash-ready indicator of the attached flash unit
before shooting.
• The TTL Auto Flash or Programmed Auto Flash mode
can be used even when the camera is set in the [bulb)
mode.
• When mounting the AF080C ring flash on the camera's
hot shoe, use the Hot-shoe Adapter F which makes it
easier to operate the shutter-release button.
