Auto OK
When the subject is within the Auto Effective Range and there is enough light, the
"Auto OK" symbol in the LCD display will blink for about 2 seconds after the flash
has been fired.
If the symbol goes out, then there was not enough light for an exposure. In that
case, either move closer to the object or select a larger aperture.
Even if the subject is within the Auto Effective Range, the "Auto OK" symbol may
not blink due to the color of an object (dark color with low reflectivity).
If the flash is fired immediately after the Ready Light comes ON, the effective
range may be reduced. (Please wait 5 to 10 seconds after the Ready Light is ON
to achieve maximum power.)
Test Flash
If the Test Button is pressed after the Ready Light is on, it fires the flash. The Auto
OK cannot be used for TTL test flash.
Autofocus Infrared Assist Light
When used in the dark or in low-light conditions, the PZ40X emits an infrared
auxiliary light when the camera's shutter release button is lightly pressed.
The camera's Autofocus system uses this light to achieve better autofocus
performance.
2. Press the shutter release button of the camera
partway in to check whether the correct aperture and
shutter speed are selected.
*Important. Note that the effectiveness of the bounce
flash feature is dependent upon the distance to, and
the condition of the reflecting surface used.
The angle of the flash must also be set properly to
achieve the best possible lighting effects. Aim the
flash head at a point on the bounce surface, halfway
between the flash and the subject. Normally, when
the flash is bounced off a surface, it will usually lose
25 % power or more, even when the surface is white.
Therefore, when a bounce flash photo is taken in TTL mode, it is recommended
that you select a larger aperture than for a direct flash photograph.
*Bounce your flash off a white surface whenever possible to achieve the best
overall illumination level. Please note that in color photography, when a colored
surface is used for bounce lighting, it will reflect its color on the subject.
*When the PZ40X is set to any bounce lighting position, the distance range is not
displayed.
Adjustable Bounce Flash Head
The SUNPAK PZ40X includes a flash head that allows you to position the light
in a number of vertical positions, in all exposure modes, even in TTL. For more
pleasing and creative lighting effects, such as softening shadows on a subject, the
Bounce Flash Head of the PZ40X is adjustable vertically up to 90 degrees.
1. Do not attempt to force the Head beyond the settings available, or damage to
the flash unit will occur.
