PENTAX
AF200SA
AUTOMATIC ELECTRONIC FLASH UNIT
The AF200SA has a Guide Number of 20 with ISO 100 film, and when
used with any Pentax programmed camera, becomes a high-performance,
clip-on type flash unit that easily gets ready for flash photography by just
turning the power switch to ON. Can also be used with the camera set to
the Aperture-priority AE mode. Its wide angle of illumination can cover
the area seen by a 28mm wide-angle lens.
The AF stands for Auto Flash Unit, and it has an electronic sensor that
measures the amount of light reflected from the subject instantaneously.
It turns the flash off automatically when the sensor registers enough light
for correct exposure. This eliminates the need to measure distances and
change the f-stop each time you move in relation to the subject.

1. Slide the battery chamber cover down and open
it by raising its bottom part.
2. Insert four AA-size batteries into the chamber
with their (+) (-) sides placed exactly as indicated
inside the chamber. Close the cover.
3. Turn the power switch to ON, and in several
seconds the flash-ready lamp will light up. Press
the test button, and make sure the flash fires. If
the flash-ready lamp does not light, the batteries
may be loaded improperly or worn out. Be sure to
turn the switch off after the test flash.
CONTROL RANGE 0 8-5 m
26-16
Use four AA-size batteries mentioned below.
Manganese batteries
Alkaline batteries
Ni-Cd rechargeable batteries (You need
a battery recharger.)
® Remove batteries when not using the flash unit
for long periods of time. Batteries tend to leak if
left too long in the unit and may cause serious
damage,
e Batteries are very sensitive to cold and
performance tends to deteriorate at temperatures
near freezing. Performance is restored to normal
as soon as batteries are subject to room
temperatures. Keep a set of spare batteries warm
in your pocket when shooting in freezing weather
to substitute when the others become cold.
® Battery performance tends to differ depending
upon brand and type. Best results are obtained
when high-performance alkaline batteries are used.
Rechargeable Ni-Cd (nickel-cadmium} batteries
offer the advantage of shorter initial recycling
time and rechargeability, but give less number of
flashes per charge.
® Replace batteries at the same time. Do not mix
battery brands and types, or old batteries with
new batteries.

Slide the hot-shoe bracket of the flash unit into
the camera's hot shoe completely, then tighten
the thumb screw above the bracket by turning it
to the direction of the arrow to fix the bracket.
The flash unit can be dismounted by first loosening
the thumb screw.
e [f the flash unit is not properly mounted, it does
fire, but may not provide proper flash sync. To
avoid this problem, always make sure that the %
mark appears in the viewfinder, which indicates the
proper mounting of the flash unit.
e When mounting or dismounting the flash, be
sure to do it while holding somewhere around the
hot-shoe bracket, not the flash head, in order to
avoid any damage.
COMPATIBLE CAMERAS AND EXPOSURE MODES
The AF200SA is an electronic flash designed to
work with a programmed camera. As shown in the
table below, it can be used in the Aperture-priority
AE mode as well.
As soon as the flash has been fully charged, the
functions of the camera and lens are automatically
set as indicated in the table,

1. Turn the power switch to ON. When the
flash-ready lamp on the flash lights up, the flash
is ready to fire.
2. The % mark also appears in the viewfinder to
indicate the flash is ready to fire,
3. Focus on the subject, then make sure that it
is within the flash range (0.8—5 m), and release
the shutter.
4, Be sure to turn the switch to OFF after shooting.

USING WITH OTHER CAMERAS
You can also use the AF200SA with any other
non-programmed Pentax camera that has a hot
shoe on top of the pentaprism, as a conventional
auto flash,
1. Set the camera's shutter speed to X (flash-sync
speed).
2. When using ISO 100 film, set the aperture to
f/4. With any other film, set the aperture as
indicated in the table on page 7.
3. Whatever the film speed may be, the flash range
is fixedly 0.8—5 m. Refer to the camera's operating
manual as well.

Caution: If the AF200SA is used with any camera
other than Pentax, it may cause malfunction or
harm the electronic mechanism of the camera.
| FLASH-READY LAMP (READY/TEST) ——
Or
ASAR! OPT, CO. JAPAN
— ON CONTROL RANGE 0 8-5 y
YA UES
When the flash-ready lamp is on after the power
switch is turned on, you are ready to fire the flash,
but you had better wait a few seconds to fire the
flash, as it makes the flash output more stable than
just after the flash-ready lamp is on.
Caution: If you leave the AF200SA switched on,
using it with the Pentax cameras (except A3/A3000
and P3/P30) in the table on page 6, the camera's
meter stays ON as well, thus exhausting the battery
power. When the flash is not in use, be sure to turn
the power switch of the flash to OFF.

WIDE-ANGLE (AFW1) AND TELEPHOTO (AFT1) ADAPTERS |
12
Slide either adapter into the grooves on top or at
the bottom of the flash illuminator until it stops
with a click. Using the AFW1 adapter broadens
the flash angle as wide as the 24mm wide-angle lens
can see or cover the subject. Using the AF T1
improves the result obtainable with telephoto
lenses from 85 to 200mm by providing more
concentrated light output to the subject.
When these adapters are used, the flash range
changes as follows:
AFW1 = 0.6—3.5 m (2—11.5 ft.)
AFT1 = 1.2—7 m (4.7—23 ft.)

SPECIAL NOTES ON FLASH PHOTOGRAPHY
e |f you take a flash photo of two persons, one
very near and the other distant, in one picture
frame, the near person tends to be overexposed.
So, in such a case, keep an extremely near subject
out of the frame.
e If the subject you are shooting in places like
a theater is small, not in the center of the picture
area, and the central background is black, it tends
to be overexposed.
