Pentax SF10 - Using Pentax Dedicated Flash Units

USING PENTAX DEDICATED FLASH UNITS
If the camera is set in an AE (automatic exposure) mode
or the Metered Manual mode, a Pentax dedicated auto
flash unit can be used anytime.
How to Use an Accessory Flash
1. Remove the camera's hot-shoe cover and attach the
flash unit.
2. Set the flash mode to TTL Auto or Programmed
Auto.
3. Turn the flash's main switch on.
• The completion of the flash-charging operation can be
confirmed by checking the flash unit's flash-ready
indicator, as well as the flash-ready indicator [ H in
the viewfinder which is turned on when the shutter
release button is pressed halfway down. (The indications
for the RTF are slightly different.)
• As you remove your finger from the shutter-release
button the ( S ] mark and the glowing of a shutter speed
disappear about five seconds later.
• For this camera, please take advantage of the
AF400FT2 or AF240FT flash, which possesses the
many capabilities shown at right.
Functions of RTF and Dedicated Auto Flash Units
e When using an old-type flashunit (AFlSOSor AF200S),
use the lens aperture ring to select the desired f-number.
• The flash unit may not discharge if the subject is too
bright to require a flash.
e * The [ ^ ) mark appears in the LCD panel when the
flash is fully charged.
e * AF200SA, AF240Z and AF160SA apply.
TTL Auto Flash System
When you attach a Pentax dedicated TTL auto flash unit,
the camera's metering circuits automatically control the
flash output for a proper exposure by measuring the
incoming light reflected off the film plane. Since this
system measures only the light reflected by the subject, it
ensures accurate exposure control.
