Notes on Use
•
Do
not
leave the lens exposed
to
the sun or a bright
light source. Internal malfunction
of
the camera body
and lens, smoke, or a fire may result due
to
the effect
of
light focusing.
If
circumstances necessitate leaving
the lens in sunlight, be sure
to
attach the lens caps.
• When shooting against the sun, keep the sun
completely
out
of
the angle
of
view. Otherwise, solar
rays
may
be
concentrated at a focal point inside
the camera, causing smoke
or
a fire. Keeping the
sun slightly
out
of
the angle
of
view may also cause
smoke or a fire.
• When carrying a camera with the lens attached,
always firmly hold both the camera and the lens.
• This lens
is
not water-proof, although designed
with
dust-proofness and splash-proofness
in
mind.
If
using
in
the rain etc., keep water drops away from the lens.
•
If
the lens alone
is
shaken or
if
a camera with the lens
attached
is
shaken while the camera
is
turned off,
an
internal component
of
the lens may rattle. This,
however, does not indicate a malfunction.
and the red dot
on
the lens hood
is
aligned
with the
red
line
on
the lens.
•
Be
sure
to
rotate the lens hood until
it
clicks into place
to
prevent its disengagement from the lens.
• When using a built-in camera flash
or
an
external flash
(sold separately) attached to the camera, remove the
lens hood to avoid blocking the flash light.
• When using the lens hood, attach the
front
lens cap
over the lens hood.
• You
can
attach a filter over the lens hood. Depending
on the type
of
filters, you can attach the lens hood
after attaching a filter over the lens
as
well.
