When switching on the unit the
autofocus is automatically switched
on too. The correct focus is
continuously adjusted at a very high
speed. The green light beside the
autofocus on/off switch (9) indicates if
the autofocus is on.
Please note that objects with very low
contrast (like a blank sheet of paper)
are difficult to focus. If the autofocus
does not work just move the object
slightly.
For special applications the
autofocus can also be switched off
using the on/off switch (9). The
autofocus is also switched off when
the manual zoom keys of the VZ-7D's
remote control are used.
If you work with a VZ-7D you can use the FOCUS-
keys of the remote control for manual focusing. If
the remote control is not available or if your
Visualizer is a VZ-5F, use this method:
1. Place an object at the level you wish to focus
The autofocus is now focusing the object.
2. Switch off the autofocus with the on/off switch (9).
The focus remains unchanged from now on.
In order to prevent reflections the light of the
Visualizer always has to be switched off
when working with lightboxes.
Connect the power cord to the Lightbox
connector (15) on the back side of the
Visualizer. The light switch (6) of the Visualizer
can now be used to switch between the light
of the Visualizer and the light of the Lightbox.
When the Visualizer is switched on it works with a precise automatic white balance.
Please note that immediately after the unit is switched on, the white balance adjustment
may not be 100% correct. In this case just move any object in the picture. From this
moment on it works perfect.
Turning the light backwards
In order to enable recordings
with illumination outside of
the working surface, the light
of the Visualizer can be
horizontally turned an angle
of up to 250°.
In order to eliminate reflections
(on high gloss photographs
etc.) just turn the light
backwards slightly.
Please note that reflections
can also be caused by the
room light.
.
For shooting an object outside the working surface, in
a further distance to the unit, the close up lens (7) has
to be removed. In this case just pull the lens away
from the main optic of the camera until it reaches the
locked position. It is impossible to remove the lens
completely from the unit, thus it can not get lost.
Before turning back the camera into the standard
working position push the close up lens back in.
