General Precautions

Handling Precautions

Do not leave the product in excessive heat such as
z
in a car in direct sunlight. High temperatures can
cause the product to malfunction.
If the lens is taken from a cold environment into a
z
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.
When the lens is not attached to the camera or the
z
power switch of the camera is in the off status when
the lens is attached, shaking the lens may cause
the internal lens group to shift and noise may occur,
but this is not a malfunction. Although the internal
lens group shifts due to vibration such as when the
lens is carried, this will not affect aspects such as
performance.
In order to optimize aperture control, there are
z
occasions in which the aperture blades will move
during focusing, even when the aperture value is
set for aperture-priority AE or manual exposure, etc.
Please also read any lens related handling
z
precautions listed in your camera's instruction manual.
Shooting Precautions
Focus again after recovering from the auto power
z
off status.
To maintain the focus position in the shooting-ready
z
status, set [Auto power off] to [Disable] on the
camera.
