Reduce or enlarge the distance between the test chart and the image plane of the camera by a maximum of
5 cm or 2" to obtain maximum image sharpness on the live view. Keep the focus ring at the testing distance.
See
Shimming Table
• If you measured the sharpness below the testing distance you need to reduce the distance between the test chart
and the image plane of the camera.
• If you measured the sharpness above the testing distance you need to enlarge the distance between the test chart
and the image plane of the camera.

Now remeasure the testing distance between the image plane mark on the camera body and the test chart
(= the actual distance)
•
If the testing distance has changed, note the distance. The change indicates that the flange focal distance of the
ZEISS CZ.2 must be adjusted. Proceed with the steps in
Correcting the Flange Focal Distance
.
Do not take down the setup as you will need it again to recheck the sharpness later in the process.
