You will find information on using each lens in this manual. Precautions
common to lenses, such as notes on use will be found in "Precautions
before using" on a separate sheet. Be sure to read both documents before
using the lens.
This lens is designed for Sony α mount cameras (models equipped with
ˎ
ˎ
APS-C sized image sensor). You cannot use on 35mm-format cameras.
ˎ
ˎ
Notes on use
ˎ
ˎ
ˎ
ˎ
When using this lens with an E-mount camera, attach a separately sold Mount
Adaptor. Do not attach the lens directly to the E-mount camera or you may
damage both.
ˎ
ˎ
When you carry the camera with the lens attached, make sure to hold both the
camera and the lens steadily.
ˎ
ˎ
Do not hold by any part of the lens that protrudes when zooming or focusing.
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.
Vignetting
When you use lens, the corners of the screen become darker than the center.
To reduce this phenomena (called vignetting), close the aperture by 1 to 2
stops.

To remove the lens (See illustration –.)
While pressing and holding the lens release button on the camera,
rotate the lens counterclockwise until it stops, then detach the lens.
 Attaching lens hood
It is recommended that you use a lens hood to reduce flare and ensure
maximum image quality.
Align the red line on the lens hood with the red line on the lens (Lens
hood index). Turn the hood clockwise until the red line on the lens
meets the red dot on the hood and it clicks into place.
ˎ
ˎ
When using a built-in camera flash, make sure to remove the lens hood to avoid
blockage of the flash light.
ˎ
ˎ
Attach the lens hood properly. Otherwise, the lens hood may interfere with the
desired effect or may appear in pictures.
ˎ
ˎ
When storing, turn over the lens hood and place it onto the lens backwards.

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.
ˎ
ˎ
This lens is equipped with a distance encoder. The distance encoder allows more accurate measurement (ADI) by using a flash for ADI.
ˎ
ˎ
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.

 Zooming
Rotate the zooming ring to the desired focal length.
Zoom lock
This prevents the lens barrel from extending due to the weight of the lens
while it is carried.
Slide the zoom lock switch to lock. To unlock, slide the zoom lock switch
back.
 Focusing
When using the auto focus, the camera focuses the lens automatically.
ˎ
ˎ
While the camera is auto focusing, do not touch the focusing ring as it rotates.
Only rotate the focusing ring manually when the camera is set to the direct
manual focus, otherwise a malfunction may result.
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 condition of the focus.
ˎ
The focusing ring can be rotated slightly past the infinity to provide accurate
ˎ
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.
ˎ
For Lens model DT 18-250mm F3.5-6.3, the focusing ring rotates the opposite
ˎ
way than standard A-mount lenses.
Remove the rear and front lens caps and the camera body cap.
ˎ
ˎ
You can attach/detach the front lens cap in two ways, (1) and (2). When you
attach/detach the lens cap with the lens hood attached, use method (2).
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.
ˎ
ˎ
Do not press the lens release button on the camera when mounting the lens.
