HOW - TO USE ZEISS SHARP MAX™ COLLIMATION DEVICE

• Insert the lens into the bayonet of the camera

• Turn the focusing ring of the lens to infinity

• Turn the aperture ring to maximum aperture

• Turn the back-focus ring to the 0 marking

• Loosen the locking screw on the lens flange of Sharp Max

• Slip the lens flange on the DigiPrime lens

• Slightly tighten the locking screw on the lens flange

• Switch on the camera. Switch on the 'Zebra' function of 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 surroundingsg with high contrast and the center of the siemns 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
