Welcome to the worldwide family of Sunpak Owners. Your Sunpak PZ40X is
specially designed for NIKON AF-SLRs as well as some Nikon type digital
cameras. The PZ40X can also work with cameras having a non-dedicated,
single-contact hot shoe. Your new PZ40X has many unique features; please take
a few minutes to read this owner's manual carefully.
Features and Function of the Sunpak PZ40X
* Multi-step Auto Power Zoom function automatically provides optical flash coverage
matched to the focal length of the lens in use. (24-80mm)
* Super-compact size. This unit is 40% smaller and 2-1/2 oz. (70g) lighter than previous
flash units with the same features and power output, making it far easier to handle
on-camera, while taking up little space in your camera bag.
* With A-group cameras, you can use the PZ40X in the 3D Multi-Flash mode (with D-type
lens only) and Multi-Flash mode (both modes employ a pre-flash for accurate measurement
of distance to subject).
* With A-, B- and C-group cameras, the TTL Auto Mode calculates and outputs the optimal
flash level automatically.
* With D-group cameras, you can use the D-TTL mode for the most precise flash-exposure
management.
* A large, easy to read LCD panel displays all the information needed to monitor and control
all flash settings. The panel can be illuminated for easy reading in dark conditions.
The data display remains on for 20 seconds after pressing the display button.
* The PZ40X has a built-in auto-focus assist light, which comes on automatically to aid
auto-focusing at low light levels.
This owner's manual is written for four groups of NIKON cameras; Group A, B, C,
& D as follows:
Your NIKON
Group
F5, F100, N90 series, F80, N80, F70D, N70

* The PZ40X provides five Manual flash output settings, from full power to 1/16.
* The PZ40X has a power-saving function that turns the unit off automatically if it hasn't
been used for 5 minutes. This energy-saving feature reduces battery consumption.
* The PZ40X flash head can be tilted upward incrementally to a full 90 degrees (vertical),
for convenient bounce flash capability.

you hold onto the PZ40X only, your camera may slip off the flash foot and be damaged,
or the weight of the camera may damage the flash foot.
*If you use PZ40X with cameras other than NIKON AF series SLRs, you can only use it
in Manual Mode. Please refer to Page 17.
*Depending on the type of lens used, the distance may not be indicated on the LCD
Display.
Important: Flash coverage limitations
When using a lens with a focal length less of than 24mm, the PZ40X will not cover the
entire field of view, and the edges and corners of the image will be dark. Also, the overall
exposure may not be correct. Please use this unit with lenses of 24mm or greater focal
length.

Power Zoom Head
Multi-area BL Mode
A
2428355080
The PZ40X is equipped with a motorized zoom
head. It is controlled by the camera and is set
automatically to provide optimal flash coverage
for the focal length of the lens in use. It can even
select intermediate settings within the 24-80mm
focal length range. Or, it can be manually set
select to 24, 28, 35, 50, and 80mm by using the
Manual Zoom Mode.
You can use the Multi-area BL Mode when
you use an A-group camera. When using the
PZ40X, an A-group camera switches to MULT
Mode when an input button is pushed, and
3DMULT is displayed as shown in the figure
at right. (The last setup will be displayed if a
switch is turned on.)(Only the TTL Mode is
displayed when using group B- and C-group
cameras.) In response to a signal from the camera, the flash unit calculates the
correct flash exposure based on the film speed, sets the aperture instantly, and
displays the effective TTL flash range on the PZ40X LCD panel. The flash unit
determines the optimum amount of light required for a proper exposure with films
from ISO6 to 6400. The available range will be displayed when you partly depress
the camera's shutter release, or when the Ready Light is on.
mmmmmmmmmm
TTL
* Auto Power Zoom works only with lenses of 24mm or
greater focal length.
* When using A-, B-, and D-group cameras with NIKKOR lenses,
the Auto Power Zoom function can be used. With other lenses, use the manual
(M-Zoom) Mode.
The flash range is from 1.5 ft to 100 ft (0.5 to 32m) and is indicated by means of a
bar graph. An asterisk indicates distances greater than 100 ft (30m).
* Multi-area BL is the advanced TTL function that enables the flash to balance the
light between subject and background to provide the best overall exposure.
Using the PZ40X with Digital Cameras
D
TTL Mode Setting
With digital cameras (such as the Nikon D-100), both TTL Autoflash Mode and Manual
Mode are available. Please refer to Page 6. When taking a picture, the Ready light blinks at
first and then lights steadily. While you can take a picture as soon as the ready light blinks,
we recommend that you wait for the Ready Light to remain on before shooting to insure that
you get the best exposure.
3D Multi BL Mode (Group A camera) .... The most advanced BL mode to
have the optimal flash. The pre-flash result and distance information from the D
lens controls the amount of flash volume. This function is available only when
a group A camera is equipped with D type lens.
Multi BL Mode (Group A camera) .... This also performs a pre-flash, and
controls the amount of flash by TTL measurement. This function is available
when using an AF lens other than D type lens.
* If it takes longer than a few seconds for the Ready Light to illuminate, or the Ready Light
doesn't light at all, please replace the batteries or charge rechargeable batteries.
TTL Mode (All of NIKON AF cameras).... This gives the optimal aperture to an
object all the time. The brightness of the background is not, so that the object
sometimes becomes too bright.
* We recommend that you use Ni-MH batteries for faster recycling and more flashes per
charge.

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.)
2. Press the shutter release button of the camera
partway in to check whether the correct aperture and
shutter speed are selected.
Test Flash
*Important. Note that the effectiveness of the bounce
flash feature is dependent upon the distance to, and
the condition of the reflecting surface used.
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.
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.
Adjustable Bounce Flash Head
*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.
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.
*When the PZ40X is set to any bounce lighting position, the distance range is not
displayed.
