Examine the lens and hardware as shown in Figure
2. The lens consists of a single focus barrel. The lens
is secured in place with a lens locking ring.
Additionally, the lens consists of a metal lens cover
which is screwed in-place. To remove the lens cover,
rotate the cover counterclockwise (CCW) and place
in a secure location for reuse. To focus the lens,
loosen the lens locking ring. Note; the lens locking
ring employs fine threads and requires multiple turns.
Once loosen, rotate the lens barrel until the desired
focus is achieved.
