3. SWITCH THE FLASH ON
Make sure that the camera is switched
on. Then simply slide the ON/OFF switch
(8) to the right. If the batteries are fresh
the gun will charge up in less than 12
sec. and the ready light (7) will glow. If
the gun is new, or hasn't been used for
a while, fire the flash with the test but-
ton (6) a couple of times to get the
flash working at full capacity.
Note:The flash exposure is controlled
via the camera's
Though-the-lens
(TTL)
and
"Off-the-film"
(OTF) systems. There-
fore if the flash is tested on camera
without a film or test card loaded incor-
rect flash operation will result.

HOW
TO POSITION THE BOUNCE
AND SWIVEL HEAD
The 700AF offers the advantages of a
zoom head with tilt and swivel facili-
ties.
Zoom head. By pre-setting the zoom
head to match the lens in use you can
obtain even light coverage with wideangle
lenses and still maximise the flashgun's
power output with longer lenses.
Simply set the number on the head
(1)
that most closely matches the focal length
of the lens. So if it's an 85mm lens or
longer, set 85; standard lens, set 50;
35mm lens, set 35; and 28mm
lens,
set 28. Don't forget to alter the zoom
head when using a zoom lens.
Note:For 24mm lenses set the zoom
head to 28 and fit the wideangle dif-
fuser. This will cause slight underex-
posure by about 1 stop, which is not
noticeable with colour print film.

Tilt and
swivel.The
700AF's head can be tilted upwards and swivelled
sideways to bounce the light off white or neutral coloured surfaces. This
gives a much more flattering result, preventing washed-out highlights
reducing harsh shadows and eliminating red-eye. The head can be
tilted from Odeg (straight ahead), through 45, 60 and 75deg to 90deg
(straight upwards). It will also swivel right through to
180deg,
useful for
bouncing the light off a wall.
5. SELECT AN EXPOSURE MODE
For simple point-and-shoot photography, leave your camera in Program
mode. However, the Cobra 700AF's advanced dedication allows you to
choose any other exposure mode
available
e.g. aperture priority, shut-
ter priority and manual. Further details for using this flashgun with
specific cameras is provided overleaf.
6. FILM SPEED SELECTOR/DISTANCE SCALE (5)
This scale can be used as a guide to maximum shooting distances,
especially useful when using the camera in its TTL manual mode. The
scale is not electronically connected to the flash unit and its use will not
affect the flash output, which is completely controlled by the camera.
7. AF ILLUMINATOR
The 700AF has a built in autofocus
illuminator (12) to enable the camera
to judge the distance, and adjust the
focus of the lens in low ambient light or
total darkness. The illuminator fires a
red light when the shutter release but-
ton of the camera is pressed. The camera
can then adjust the focus of the lens
and when correct will fire the shutter
and the flash. The illuminator has an
effective distance of 7 metres. Beyond
this distance manual focus should be
used.

white wall or ceiling gives a more
flattering result to portraits
