4. When the image geometry appears correct, tighten the
Anamorphic Lens Set Screw (item #10) to secure the lens in place.
(When viewed from the front, the rear opening on the anamorphic
lens should appear as a tall, narrow oval.)
Focus: Finally, rotate the Focus Ring on the anamorphic
lens to fine-tune the optical focus.
