ground exposure for better background detail and also creates a more
natural lighting balance between the subject and the background.
Select SHUTTER-PRIORITY AE mode on the camera (refer to cam-
era's instruction book) and select any shutter speed from the maximum
sync to the slowest speed of particular model. The camera will select
an appropriate aperture.
APERTURE-PRIORITY AE MODE (ALL MODELS EXCEPT
This mode allows the user to select any aperture and is useful when
is an important factor. Select APERTURE-PRIORITY AE
mode on the camera (refer to camera's instruction book) and select any
aperture. The camera will select a sync speed. The distance scale (5)
on the rear of the gun can be used as a guide to maximum shooting
distances with most apertures.
Note:
The sync speed set by the camera depends on the aperture
selected. A wide aperture i.e.
will usually mean a fast sync speed
i.e. 1/125th sec, however selecting a narrow aperture, i.e. f16, will likely
result in 1/30th sec being set.
HYPER MANUAL
& Z-20), METERED MANUAL (ALL OTHER MODELS)
This mode allows the user to select both shutter speed and
HYPER MANUAL/METERED MANUAL on the camera (refer to cam-
era's instruction book) and select shutter speed and aperture desired.
The distance scale (5) on the rear of the gun can be used as a guide to
maximum shooting distances with most apertures, film speeds etc.
Note:
The Z-1 will not allow incorrect shutter/aperture combinations to
be set and an S will appear on the camera's LCD information panel.
For more information refer to camera's instruction book.
MANUAL (BULB) (Z-1 & Z-20), BULB (ALL OTHER MODELS)
BULB allows the shutter to be kept open indefinitely for long expo-
sure shots with or without flash.
BULB on the camera (refer
to camera's instruction book). Select desired aperture.
Note: When the 700AF flash fires in this mode the auto check indicator
(9) will illuminate, this shows that the flash has correctly exposed the
subject as indicated by reflected light. It is not, however, an indication
of the over-all exposure, this will depend on the amount of time that the
shutter remains open and the reciprocity of the film in use. Some trial
and error may be required.
AF ILLUMINATION WITH 700AF
VERSION
A) The 700AF's illuminator
) will only operate with the Z-10 (and
only when an FA-AF Power-Zoom lens is fitted).
B) The Z-1 will only operate its own AF spot beam which is located next
to the RTF. When AF illumination is required simply engage the RTF,
focus as normal, then retract the RTF. If the RTF is left in the
position there is a possibility that it will fire along with the 700AF.
C) Low light illumination is not possible with the 700AF and Z-20,
regardless of lens type in use.
D) When using the 700AF and Pro-Grip with any model other than the
Z-10, batteries need not be used in the grip.
IMPORTANT NOTICE:
Due to circuit board differences between the SF and Z series 700AF
Pentax guns, the two are not
i.e. an SF series 700AF
cannot be used on a Z series camera, and vice versa.
EXPOSURE CHECK
If the flash exposure is sufficient the auto check indicator (9) will light
up. If it fails to light, check that you are within flash range. In aperture
priority and manual modes a larger aperture may be selected allowing
more light to strike the film.
THE FILTER PACK
Three coloured filters, a red green and blue, plus a wideangle
diffuser are included with your Cobra 700AF. These simply click
onto the front of the zoom head.
Note that the coloured filters will reduce the flashgun's light output
by about two stops, and the wideangle diffuser by about one stop.
700AF flashgun is dedicated to one brand
of camera only. Dedication cannot be changed by simply changing
the removable module (13). The
dedicated circuitry is
housed in the body of the gun not the module. The module is
removable only to allow use with the optional Pro-Grip AF outfit.
Serious damage could result to both flash and camera if this warning
is not adhered to.
