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 I SI 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 151 mark and the glowing of a shutter speed disappear about five seconds later. • For this camera, please take advantage of the AF400FTZ or AF240FT flash, which possesses the many capabilities shown at right. Functions of RTF and Dedicated Auto Flash Units • When using an old-type flash unit (AF160S or 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. • * The 15 1 mark appears in the LCD panel when the flash is fully charged. • * 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. • 48

Functions
of
RTF
and
Dedicated
Auto
Flash
Units
•
When
using
an
old
-type
flash
unit
(AF160S
or
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

•
*

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.
