the lens and adapter assembly until the two markers appear

in sharp focus.

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).
