Safety Precautions

1.

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.

2.

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 fire.

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, 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.
