LFP Quick Start Guide

Zeroing the axes manually
1.
If you have a serial lens with internal motors for the focus, zoom,
and iris then you can skip this step.
If you have a lens with external motors, set the
focus to infinity
(
∞
),
zoom to wide-angle
(zoomed out all the way), and
iris/aperture to
wide open
. Do this either with the LFP controls or by moving the
gears by hand. Also see
Zeroing lens axes with external Lens Control
.
2.
Use the controls to point the camera head in the direction that you
want to use as the zero position for the head axes. (If the head is on
rails, also use the controls to move to the zero rail position that you
want to use).
3.
In the LFP menu, choose one of the following options:
DIRECT ZERO ALL
(in Broadcast mode; this option is only available
if the Engineering menu option
HOME AXIS
>
ZEROING METHOD
is
set to
ZEROING
.)
or...
HOME AXES
>
DIRECT ZERO ALL
(in Film mode).
Hint
Some methods for finding a useful zero position are, in order of
increasing accuracy and repeatability:
•
Use the controls to point the camera straight ahead.
•
Use the controls to point the camera at a small object in
the field of view that is easy to find again in subsequent
sessions, such as the corner of a ceiling or desk.
•
Zoom in on the object and centre it in the field of view
(but remember to zoom all the way out again after
adjusting the direction so that your zoom axis will be
correctly zeroed.)
•
If you are in Film mode you can use
DIAGNOSE AXES
>
LIMIT INPUTS
to display information that tells you when
an axis crosses its home position as you move the controls.
