Modes
In the case of ZK lenses, the fstop can either be set manually
GB
using the lens aperture ring or, alternatively, using the camera
body (by locking the lens aperture ring to position „A"); this
depends on the required mode (aperture priority, shutter priority,
programmed exposure or manual exposure setting) and the
features of the camera body in each case.
For more information on available modes with manual lenses
(Pentax KA standard), please consult your camera's operating
instructions.
Depending on the features of the camera body, the ZS lens
can be used either with full aperture metering or stopdown
metering. For full aperture metering, select the desired fstop
using the aperture ring and switch the selector lever on the lens
to position „A".
When using a ZS lens on a camera body without aperture
transfer or with an adapter, lock the lens aperture to the pre
selected value by switching the lever to position „M". With many
cameras, it is then possible to carry out automatic exposure with
aperture priority.

Tips for lens care
To avoid any imperfections and humidity on the front lens sur
face, and for general protection, it is recommended to use the
lens cap as much as possible when the lens is not in use. Dust,
smudges and fingerprints on the lens surface can be gently
removed with a very soft brush and then with a dry, clean,
soft cotton cloth. The ZEISS lens cleaning kit will give superior
results and is highly recommended for this purpose.
