Nikon PZ40X - Manual (Page 7)

7
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.
* 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.
* We recommend that you use Ni-MH batteries for faster recycling and more flashes per
charge.
Using the PZ40X with Digital Cameras
Power Zoom Head
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.
* 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.

Multi-area BL 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.
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.
TTL
TTL Mode Setting
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.
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.
