2.4 Adjust the Lens
Once the image appears on the monitor, adjust the focus and diaphragm of the lens to obtain the
best picture.
When a lens does not hold focus at both ends of the zoom range, do back focus adjustment as
following:
i. Set the focus ring of the lens to infinity position.
ii. Take picture of subject at a distance more than 20m away from the camera.
iii. Loosen the lens mount fixing screw located at right-hand side of the front panel by using the
L wrench.
iv. Turn the lens and the mount together so that the subject is in focus.
v. Secure the lens mount fixing screw firmly again.
Mount the camera on the mounting bracket by using the mounting hole at bottom or top of the front
panel. (Mounting bracket is an optional accessory).
