Figure C-6: Camera back focus lock
If you are using a zoom lens, focus the zoom setting using the
zoom control as follows:
a. Zoom IN fully (lens focal length at its maximum) on the
markers and adjust the front focus to obtain a sharp image of
the markers.
b. Zoom OUT fully and slowly loosen the back focus locking ring
using the lever rods protruding on either side, as shown in
Figure C-6, and rotate the lens and adapter assembly until the
two markers appear in sharp focus.
c. Repeat steps a and b until the focus stays sharp throughout
the zoom range and no adjustment is necessary at either
extreme of the zoom range.
8. Gently retighten the back focus locking ring in a clockwise motion
and recheck the focus of the marker pair in the Vicon software.
9. If necessary, trim the focus using the front focus ring (for details,
see Adjusting Camera Lens Focus with Front Focus Ring on
page C-2).
