Axes directions
If you are using a lens with external LCMs, you need to make sure that
when you move the lens controls (focus, zoom, and iris), the axis values
(as displayed on the LFP) increase in the correct direction. To check this:
1.
Choose menu option:
AXIS POSITIONS
(in Broadcast mode)
or...
DIAGNOSE AXES
>
AXIS POSITIONS
(in Film mode)
2.
Inspect the values for the
FOCUS
,
ZOOM
, and
IRIS
displayed in the
panel, as applicable to your setup. The values are updated as you
move the controls:
•
FOCUS
axis values must increase (or become more positive) as
you focus near, and decrease as you focus toward infinity (
∞
).
•
ZOOM
axis values must increase (or become more positive)
when you zoom in (toward the telephoto end) and decrease
when you zoom out (toward the wide angle end).
•
IRIS
(aperture) axis values must increase (or become more
positive) when you close down the aperture (to, say, f/22) and
decrease when you open up the aperture (to, say, f/2.8).
