Handling Precautions
z
Do not leave the product in excessive heat such as
in a car in direct sunlight. High temperatures can
cause the product to malfunction.
z
If 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.
z
The lens interior may appear to waver, but this
does not indicate a defect or failure, and will not
cause any problems in use.
z
In order to optimize aperture control, there are
occasions in which the diaphragm blades will
move during zooming and focusing, even when
the aperture value is set for aperture priority AE or
manual exposure, etc.
z
Please also read any lens related handling
precautions listed in your camera’s instruction
manual.
