A | Introduction
Congratulations on the purchase of the Lightweight Zoom LWZ.2 lens. We are
convinced that your new lens will bring you much pleasure and success.
This zoom lens is the first on the market to combine outstanding optical image quality
with an interchangeable mount. The LWZ.2 is a cine lens designed for use with
HDSLR as well as traditional cine cameras. The interchangeable mount guarantees
high flexibility for present and future use in any situation and for a wide range of
camera platforms. With the three different mounts available (PL, EF and MFT mount)
there is no need for adapter solutions anymore. Exotic glass materials and the T*XP
anti-reflex coating ensure a sharp, high resolution image that covers the entire
Super35 frame and perfectly matches the other ZEISS cine lenses.
In this manual we take a Lightweight Zoom LWZ.2 15.5-45mm/T2.6 with EF mount,
scaled in meter as an example to explain how to change the lens mount and the
subsequent matching of your lens to a DSLR camera. Proceed in the same sequences
to switch to any other LWZ.2 mount.

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 Carl Zeiss (see appendix 3, page 11).
• Ensure that the environment is clean and free from dust so that no dust particles can
enter the lens during the adjustment.
• 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 use for shimming
only the shim set for the Lightweight Zoom LWZ.2. It is highly recommended to
handle the shims carefully as they can easily kink or tear which makes them unusable.
