FLASH
PHOTOGRAPHY

built-in
flash
will
cause barrel

if
used
with
this
lens. For

external
flash
unit.
LENS
HOOD
A bayonet
type
detachable
hood is provided
with
the
lens. This lens hood
helps
to
prevent
flare
and ghosted images caused by
bright
illumination
from
outside
the
picture
area.
Attach
the
hood and
turn
clockwise
until
it
stops
rotation. (fig.3)
+In
order
to
place
the
tens and hood
into
the
storage case, you
must
first
remove
the
hood,
then
replace
it
on
the
lens in
the
reverse position. (fig.4)
FILTER
+Only
one
filter
should be used
at
the
time.
Two
or more
filters
and/or
special
thicker
filters,
like a polarizing filter, may cause vignetting.
+When
using a polarizing
filter
with
AF
camera, use
the
"circular"
type.
BASIC
CARE
AND
STORAGE
+Avoid
any shocks or exposure
to
extreme high or low
temperatures
or
to
humidity.
+For
extended storage, choose a cool and
dry
place, preferably
with
good
ventilation.
To
avoid damage
to
the
lens coating, keep away from
mothballs
or naphthalene gas.
+Do
not
use thinner, benzine or
other
organic cleaning agents
to
remove
dirt
or
finger
prints
from
the
lens elements. Clean by using a
soft,
moistened
lens
cloth
or lens tissue.
+This
lens is
not
waterproof. When you use
the
lens
in
the
rain
or
near water,
keep
it
from
getting
wet.
It
is often
impractical
to
repair
the
internal
mechanism, lens
elements
and
electric
components
damaged by water.
+Sudden
temperature
changes may cause condensation or
fog
to
appear
on
the
surface
of
the
lens. When
entering
a
warm
room from
the
cold outdoors,
it
is advisable
to
keep
the
lens in
the
case
until
the
temperature
of
the
lens
approaches room
temperature.
