ENG-3
Handling Precautions
zDo not leave the product in excessive heat such
as in a car in direct sunlight. High temperatures
can cause the product to malfunction.
zIf the lens is taken from a cold environment
into a warm one, condensation may develop on
the lens surface and internal parts. To prevent
condensation in this case, first put the lens into an
airtight plastic bag before taking it from a cold to
warm environment. Then take out the lens after it
has warmed gradually. Do the same when taking
the lens from a warm environment into a cold one.
zThe lens interior may appear to waver, but this
does not indicate a defect or failure, and will not
casue any problems in use.
zIn order to optimize aperture control, there are
occasions in which the aperture blades will move
during zooming, even when the aperture value is
set for aperture-priority AE or manual exposure,
etc.
zPlease also read any lens related handling
precautions listed in your camera’s instruction
manual.
General Precautions
Shooting Precautions
zThis lens has a short focus distance, which means
dirt or dust on the surface of the front lens will
show up easily on photos. Use a commercially-
available blower to remove dirt or dust from the
front lens surface.

3. Focusing/Control ring
The focusing/control ring can be used as either a
focusing ring or a control ring.
Focusing/Control ring
Switching between the focusing ring and control
ring is performed on the camera.
This can only be used as a focusing ring on
cameras that do not support switching*.
Please refer to the camera’s instructions for

turning the focusing ring (focusing/control ring).
zWhen the AF does not operate after switching
the focus mode from [MF] to [AF] and when the
focus mode is not displayed on the camera’s
menu, turn the focus ring in the direction of
[Infinity] until the focusing position is within the
[AF in-focus range].
• It is not possible to switch the focus mode
to [AF] if the focus lens’s focusing position
is within the [MF-only range], at which the
