·· USING
YOUR
LENS
SAFELY
Although we have
carefully designed these lenses for safe operation, please pay special
attention
to
items marked with the
following symbols when using
this
product.
~WARNING
~CAUTION
LhwARNING
This symbol
indicates precautions that if not
followed,
could
result in serious injuries to the user.
This symbol indicates precautions that if not followed,
could
result in minor or
medium injuries to the user or
damage to the equipment.
•
Never
look
at the sun through the
lens
or
camera
for
a
long
time. Serious damage
to
the retina
or
total
loss
of
eyesight may occur,
particularly
when
looking
directly
through
the
lens.
LhcAUTION
• Do
not
leave
the
lens
in direct
sunlight
without
the
lens cap. Direct
sunlight
passing
through
the
lens will
be intensified, and
should
it
focus
on flammable
materials,
fire
may occur.
PRECAUTIONS AND
LENS MAINTENANCE
1.
Storage
and mildew prevention
• Take the
lens
out of the protective case or camera bag , and store it
in
a dry, well-ventilated place.
•
Avoid storing the lens
in
a poorly ventilated location such as a
closet, wardrobe, drawer, vehicle,
or
where insect
repellent
or medicine is kept.
• Avoid storing the lens in areas of high temperature and humidity, where there is a risk of mildew
growth.
Store the lens with a desiccant
in
a
dry
cabinet, airtight container,
or
plastic
bag.
(Leaving a saturated desiccant
in
the storage container can cause damage to the lens.
Be sure
to read the instructions that come with the desiccant before use.)
2. Be careful when handling lenses that are not dust-proof, water-resistant, or do not have simplified
weather-resistant construction
in
the rain, fog or environments
in
which sand or dust is in the
air.
3.
When the lens is not attached to the camera
body,
attach both the supplied lens cap
and
lens mount
cap
to
protect
it
from dust, etc.
4. Never use any organic solvent such as thinner, alcohol, or benzine, etc. to remove dust on the lens.
5.
The lens
is
a precise optical instrument. Be
careful
not to let it
fall,
or
subject it to strong shocks or
pressure. Use a cushion or similar pad to protect the lens
from the vibrations of motorcycles or other
vehicles, boats. etc.
6. Avoid subjecting the lens to rapid changes
in
temperature, otherwise condensation can occur on
both the inside and the outside of the
lens.
Put the
lens
in
a
plastic bag
or
camera bag, and take it
out after the lens has reached ambient temperature.
7.
Do not leave the camera with the
lens
cap off attached to a tripod or other rigid camera support. The
inner parts of the camera can be damaged by direct sunlight.
8.
Have the lens inspected by a dealer every one or two years to maintain its high performance.

FEATURES OF THE
smc
PENTAX·DA LENS
• The smc PENTAX-DA
lens
is an interchangeable
lens specifically
designed for digital
cameras. Its
image circle is specialized for image sensors in PENTAX digital SLR
cameras and its optical system is optimized for the characteristics of digital images.
• When autofocusing is finished, it is possible to make fine adjustments by hand using the
"Quick-Shift Focus System"
(see page 19 for details).
• Lenses that have
"SDM"
in
their name are equipped with a supersonic motor. When
mounted
on
a camera that supports supersonic motors, the autofocus is quiet and
smooth.
• The DA
*
55mm f/1.4 SDM uses a circular aperture. Using it when stopping down from
full aperture to about f/2.8 keeps
light
sources and other fuzzy points perfectly round.
About dustproof, water resistance, and simplified weather resistance
• Dust-proof and water-resistant lenses
DA * 55mm f/1.4

SDM
, DA * 50-135mm f/2.8ED [IF]
SDM
, DA * 60-250mm
f/4ED [IF]SDM
These DA
* lenses are dust-proof and water-resistant because each
part
is individually
sealed.
This
makes
it difficult for dust and water to
enter
the lens.
• Lenses with simplified weather-resistant construction
DA 18-55mm f/3.5-5.6
AL
WR
, DA 50-200mm f/4-5.6ED
WR
These lenses are made with a simplified weather-resistant construction by using
DA
*
lens sealing technology which makes it difficult for
water
to
enter the lens.

automatically
as
if

position,
so

The
lens uses a supersonic motor.
When
the
lens
is mounted
on
a camera
body
that
does
not
support supersonic motors (including the
KlOD
with firmware older than version 1.30),
the autofocus cannot be operated
by
either
the
AF
motor
in the camera
body
or
the
supersonic
motor.
• If
using the lens with the following cameras, and
the power is turned on, MF appears in
the
monitor,
but it does not interfere with AF operations.

When
the lens is mounted on a
camera
body
that
does
not support supersonic motors (including the
KlOD
with firmware older than version
1.30), the
autofocus is operated by the AF

in
the
camera
body.
*
In both cases focusing can
be
done
manually.
Precautions
for
using
lenses equipped with a
supersonic
motor
