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.
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.
