Safety Precautions
Do not look at the sun or a bright light source
through the lens or camera. Doing so could result in
loss of vision. Looking at the sun directly through the
lens is especially hazardous.
Whether it is attached to the camera or not, do not
leave the lens under the sun without the lens cap
attached. This is to prevent the lens from concentrating
the sun’s rays, which could cause a re.

Handling Cautions
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, rst 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.
Do not leave the lens in excessive heat such as in a car
in direct sunlight. High temperatures can cause the
lens to malfunction.
