Changing the Mount of a ZEISS CP.3 Lens
In this chapter you learn how to change the mount of a ZEISS CP.3. The procedure consist of two
parts which are both mandatory to successfully change a mount. You learn how to detach the
currently attached mount and how to attach a different mount. To make sure the ZEISS CP.3
works properly, additionally complete the subsequent procedure: Adjusting a ZEISS CP.3 to your
Digital Camera.

Make sure you successfully completed Part 1: Detaching a Mount
If you are changing to a PL mount, skip step 1 and 2, since the PL mount doesn´t have an adapter ring.
1. Carefully place the adapter ring, which came with your ZEISS Interchangeable Mount Set for the ZEISS CP.3. Make
sure the small screw in the groove of the ZEISS CP.3 sinks into groove of the adapter ring and the electrical contact
fits into the recess.

3. Place the mount on your ZEISS CP.3:
3.I PL mount: Place the PL mount on the ZEISS CP.3 in such a way that the recess of the mount lays on top of the
electrical interface. The groove on the other side of the PL mount should then also lay on top of the small screw on
the lens barrel.
3.II EF mount: Place the silver EF mount on the adapter ring in such a way that the notch aligns with the index mark.

3.III F mount: Place the F mount on the adapter ring in such a way that the notch aligns with the index mark.
3.IV MFT mount: Place the MFT mount on the adapter ring in such a way that the notch aligns with the index mark.
14
3.V E mount: Place the E mount on the adapter ring in such a way that the blue dot aligns with the index mark.
3.VI LPL Mount: Place the LPL mount on the ZEISS CP.3 in such a way that the recess of the mount lays on top of the
electrical interface. The groove on the other side of the LPL mount should then also lay on top of the small screw on
the lens barrel.

4. With the T6 torx wrench tighten the torx screws using a torque of 0.4 N
You have now successfully changed the mount of a ZEISS CP.3.
Adjusting a ZEISS CP.3 to Your Digital Camera
In the following chapter you learn how to adjust your ZEISS CP.3 to a digital camera.
This is necessary to ensure that the ZEISS CP.3 works properly and delivers the maximum image
quality. In order to perform this adjustment, ZEISS provides shims in different colors which indicate
their thickness.
You need:
Tripod
Digital camera with live view
ZEISS CP.3 that needs to be adjusted
Siemens star test chart
Measuring tape or folding ruler
Flat-blade screwdriver
At least 3,5 m or 12 ft of free space
ZEISS Interchangeable Mount Set for ZEISS CP.3 alternatively: ZEISS
Shims set
The use of tools offered by ZEISS is highly recommended. You can purchase these tools directly
from ZEISS or your trusted ZEISS Dealer. See Mount Change Accessories
16
The testing distance is measured from the siemens star test chart
to image plane on your camera.
Testing the Sharpness
1. Fasten the siemens star test chart on a wall.
2. Mount the ZEISS CP.3 on the camera.
3. Mount the camera on a tripod.
4. Position your camera at the testing distance of 3 m or 10 ft.
17
5. Level the camera.
18
6. Set the aperture of the CP.3 to full speed by rotating the aperture ring.
The aperture setting must not be changed during the adjustment process.
7. Activate the live view of your camera.
8. Select the maximum magnification of the live view.
9. Make sure that the center of the image aligns with the center of the siemens star test chart.
10. Set the focus ring according to the testing distance. See Shimming Table.
The focus setting must not be changed during the adjustment process.
11. Obtain maximum image sharpness on the live view by varying the distance between the test chart and the camera.
19
12. 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 CP.3 must be adjusted. Proceed with the steps in Correcting the Flange Focal Distance.
13. Do not take down the setup as you will need it again to recheck the sharpness later in the process.
Correcting the Flange Focal Distance
1. Remove the ZEISS CP.3 from the camera.
2. Follow the steps of chapter Detaching a Mount.
3. Determine the total thickness of the shims that already lay in the lens groove.
20
4. Increase or decrease the total shim thickness according to the tables in the appendix by using a flat-bladed
screwdriver or a pair of tweezers.
Any combination of shims is possible to achieve the required thickness and therefore the desired flange focal
distance. Always use the closest possible combination of shims.
Example:
Using a Compact Prime CP.3 35mm/T2.1 lens with an EF mount, scaled in feet and a test chart at a test
distance of 4 ft, an actual distance of 4 ft 1´ is measured. Due to the table on page 14, you add a silver shim
0.013mm to the total thickness of the shims.
5. Use a flat-bladed screwdriver or a pair of tweezers to remove or add shims.
Handle the shims carefully as they can easily kink or tear which makes them unusable.
Ensure that the colored shims lie on top of each other in the groove of the lens barrel and do not cover
the screw holes. The shims might otherwise be damaged, while screwing in the screws.
6. Follow the steps of chapter Attaching a Mount to attach a new mount.
7. Recheck the sharpness of the lens. Follow the steps of testing the sharpness once more.
21
Light Blue
a. If the testing distance has changed, follow the steps of chapter Correcting the Flange Focal Distance once more.
b. If you achieve the maximum sharpness at the testing distance proposed in the tables, you successfully tested your
Compact Prime CP.3. No further steps are required.
In this chapter you learned how to adjust a Compact Prime CP.3
