a Safety Precautions
a 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.
• Do not point the lens or camera at the sun or photograph
it. This is because the lens concentrates the sun’s rays even
when the sun is outside the image area or when shooting
with backlight, which could cause malfunction or fire.
• 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.
• Do not stand on the lens case. Falling off the case
could result in injury.
• Do not stack lens cases. A falling lens case could
cause an injury.
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.
• Do not leave the lens in excessive heat such as in a
car in direct sunlight. High temperatures can cause
the lens to malfunction.
