• Switch on the camera. Connect an external monitor to the camera, if necessary.

• Press the Power button to switch on the Sharp Max unit, view the Siemens star in

the eyepiece of the camera and adjust brightness using the 'Intensity' control. If

you want to reduce brightness even further, you can also swing in a neutral-

density (ND) filter of the camera into the beam path. Brightness has been

correctly adjusted when the circle of confusion (see below) stands out from its

surroundings with high contrast and the center of the Siemens star is not affected

by glare.

• Loosen the locking screw on the back-focus ring.

• View the image in the eyepiece of the camera or on the external monitor and

adjust it to maximum focus. Owing to the different horizontal and vertical

resolution of the CCD screen in the camera eyepiece, the circle of confusion is an

ellipse. The Siemens star has been optimally adjusted when the horizontal and

vertical extensions of the circle of confusion around the center of the Siemens

star are minimum.

• Tighten the locking screw on the back-focus of the lens.

• Loosen the locking screw on the lens flange of Sharp Max and remove the unit

from the lens.
