A. Adjusting the flange focal distance to the lens
Congratulations on the purchase of this Compact Prime CP.2 or Compact Zoom CZ.2 lens set.
We are convinced that your new lenses will bring you much pleasure and success.
The Compact Prime CP.2 lenses and the Compact Zoom CZ.2 lenses are the latest members
of the ZEISS family of lenses for digital and film cameras. They deliver great flexibility by
introducing interchangeable mounts that allow the lenses to be used with a wide range of
cameras, from traditional cine to HDSLR systems. Available in five different mounts – PL, EF, F,
Micro 4/3 and E – this new family of ZEISS lenses enables cinematographers to be completely
free in their choice of camera systems. The Compact Prime CP.2 and Compact ZoomCZ.2
lenses cover the full-frame image format without vignetting.
In this manual we take a Compact Prime CP.2 35mm/ T 2.1 with EF mount, scaled in feet
as an example to explain how to change a lens mount and the subsequent matching of
your lens to a DSLR camera. Proceed in the same sequences to switch to any other CP.2 or
CZ.2mount.
B. Overview
General instructions
• The use of a T6 torque wrench with a torque of 0.4 Nm is strongly recommended.
This wrench can be purchased from ZEISS (see appendix, page 17).
• Ensure that the environment is clean and free from dust so that no dust particles can
enter the lens during the following procedure.
• Smudges and fingerprints on the lens surface can be gently removed with a soft brush
and then with a dry and clean cotton cloth. The ZEISS lens cleaning kit will give superior
results and is highly recommended for this purpose.
• When matching the lens, 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.
• Please handle the shims carefully as they can easily kink or tear which makes them unusable.

C. Changing the mount
1. Remove the rear lens cap.
2. Remove the four torx screws of the silver EF mount with a T6 torque wrench
and place the mount and the screws on one side.
The size of the black inner ring depends on the focal length of the lens and is securely
fastened to the EF mount (or F, MFT or E Mount) at the factory.
3. Remove the eight torx screws of the black EF adapter ring and place the ring
and the screws on one side.
The silver support bracket is already installed on the EF adapter ring at the factory and does
not need to be removed.

4. Now you see the colored shims in the groove of the black lens barrel.
5. Place the PL mount on the lens in such a way that the groove on the rear side
of the PL mount fits over the silver screw on the lens barrel.
6. Tighten the eight torx screws with the T6 torque wrench using a torque of 0.4 Nm.
7. When the torx screws have been tightened, the lens can be fitted to a camera
with a PL mount and used.
8. Check the flange focal distance of the lens (see section D) in combination with your camera.

Instructions on changing to an EF or to any other CP.2 or CZ.2 mount
1. Ensure that the groove on the rear side of the black EF adapter ring fits over
the small screw of the lens barrel.

on the mount has the same orientation as the ZEISS logo and the support bracket points
to the serial number on the lens barrel.
3. Please note the correct orientation of the F mount to the ZEISS logo.
