Sony a200 Instruction Manual page 162

When using the auto focus, the camera focuses the lens automatically.
When focusing manually, set your camera to the manual focus and rotate the
focusing ring while looking through the viewfinder. The focus signal in the
viewfinder indicates the current degree of the focus.
• The focusing ring can be rotated slightly past the infinity to provide accurate
focusing under various operating temperatures. Do not rotate the focusing ring
all the way to the end when focusing manually, even at infinity. Look through the
viewfinder and set the focus precisely.
• For Lens model DT 18-200mm F3.5-6.3, the focusing ring rotates the opposite
way than the other DT Zoom lenses.

Focusing
Rotate the zooming ring to the desired focal length.
Ii] Zooming
• Do not press the lens release button on the camera when mounting the lens.
• Do not mount the lens at an angle.
Cleaning the lens
• Do not touch the surface of the lens directly.
• If the lens gets dirty, brush off dust with a lens blower and wipe with a soft,
clean cloth (Cleaning Cloth KK-CA (optional) is recommended).
• Do not use any organic solvent, such as thinner or benzine, to clean the lens or
the camera cone.

Attaching/detaching the lens
It is recommended that you use a lens hood to reduce flare and ensure
maximum image quality.

Align the orange index on the lens barrel with the orange
index on the camera (mounting index), then insert the lens
into the camera mount and rotate it clockwise until it locks.

To attach the lens (See illustration
m-[1].)
DT 18-70mm F3.5-5.6:
Fit the hood into the mount on the end of the lens barrel and
rotate the hood clockwise until it clicks.
DT 11-18mm F4.5-5.6, DT 18-200mm F3.5-6.3:
Align the red lines on the lens hood and the lens. Turn the hood
clockwise until the red line on the lens meets the red dot on the
hood and it clicks into place.
• When using a built-in camera flash, make sure to remove the lens hood to avoid
blockage of the flash light.
• If a marking (red line, red dot, etc.) is provided, attach the lens hood properly.
Otherwise, the lens hood may interfere with the desired effect or may appear in
pictures.
• When storing, turn over the lens hood and place it onto the lens backwards.

Attaching lens hood
While pressing and holding the lens release button on the
camera, rotate the lens counterclockwise until it stops, then
detach the lens.
1
Remove the rear and front lens caps and the camera body cap.
• You can attach/detach the front lens cap in two ways, (I) and (2). When you
attach/detach the lens cap with the lens hood attached, use method (2).
You are cautioned that any changes or modifications not expressly approved
in this manual could void your authority to operate this equipment.
To reduce fire or shock hazard, do not expose the unit to rain or moisture.
Do not directly look at the sun through this lens.
Doing so might harm your eyes or cause loss of eyesight.
Keep the lens out of reach of small children.
There is danger of accident or injury.
This manual is for use with several different lenses.
This lens is designed for Sonya mount cameras (models equipped with
APS-C sized image sensor). You cannot use on 35mm-format cameras.

Notes on use
• Do not leave the lens in direct sunlight. If sunlight is focused onto a nearby
object, it may cause a fire. If circumstances necessitate leaving the lens in direct
sunlight,
be
sure to attach the lens cap.
• Be careful not to subject the lens to mechanical shock while attaching it.
• Always place the lens caps on the lens when storing.
• Do not keep the lens in a very humid place for a long period of time to prevent mold.
• After attaching the lens, do not carry the camera by holding the lens.
• Do not touch the lens contacts. If dirt, etc., gets on the lens contacts, it may
interfere or prevent the sending and receiving of signals between the lens and the
camera, resulting in operational malfunction.
Precautions for flash use
• With certain of lens/flash combinations, the lens may partially block the light of
the flash. resulting in a shadow at the bottom of the picture. When using a built-
in camera flash, make sure to remove the lens hood and shoot from at least 1m (3.3
feet) away from your subject.
• The built-in flash cannot be used with DT 11-18mm F4.5-5.6. Use a separately
sold flash.
Vignetting
• When you use lens, the comers of the screen become darker than the center. To
reduce this phenomena (called vignetting), close the aperture by I to 2 stops.
• With certain of lens/filter combinations, the frame of the filter may block the
incident radiation. This may significantly lower the light intensity when shooting
with the aperture wide open (low f-stop). Take test photographs at different
aperture settings for best results. (DT ll-18mm F4.5-5.6 only)
Condensation
If your lens is brought directly from a cold place to a warm place,
condensation may appear on the lens. To avoid this, place the lens in a plastic
bag or something similar. When the air temperature inside the bag reaches
the surrounding temperature, take the lens out.

The values for equivalent 35mm-format focal length and angle of view are based on Digital Single Lens Reflex Cameras equipped with an APS-C sized image sensor.
., Minimum focus is the shortest distance from the image sensor to the subject.
• This lens is equipped with a distance encoder. The distance encoder allows more accurate measurement (ADO by using a flash for AD!.
• Depending on the lens mechanism, the focal length may change with any change of the shooting distance. The focal length assumes the lens is focused at infinity.
