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 manual is for use with several different lenses.
This lens is designed for A-mount, which can be used on Sony α cameras
(models equipped with APS-C sized image sensor). You cannnot use on 35
mm-format cameras.
The DT 18-55mm F3.5-5.6 SAM is used for illustrations in this book, unless
otherwise mentioned.
Notes on use
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.
If you purchase the DT 18-55mm F3.5-5.6 SAM as part of a kit, the standard rear
lens cap ALC-R55 is not included, and the packaging lid is attached instead.
When you carry the camera with the lens attached, make sure to hold both the
camera and the lens steadily.
Do not hold by any part of the lens that protrudes when zooming or focusing.
Precautions for flash use
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. 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 the Ring Light* or Macro Twin Flash Kit* with the DT 50mm F1.8
SAM or DT 30mm F2.8 Macro SAM, use the Macro Light Adaptor*.
* Ring Light, Macro Twin Flash Kit and Macro Light Adaptor are sold
separately.
The DT 18-55mm F3.5-5.6 SAM or DT 55-200mm F4-5.6 SAM cannot be used with
Ring Light or Macro Light Adaptor.
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.

Attaching/detaching the lens
To attach the lens (See illustration
–
.)
1 Remove the rear and front lens caps and the camera body
cap.
You can attach/detach the front lens cap in two ways, (1) and (2). When

1
The values for equivalent 35mm-format focal length and angle of view are based on Interchangeable Lens Digital Cameras equipped with an APS-C sized image sensor.
*
2
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 (ADI) by employing a flash for the process.
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.

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.
Do not press the lens release button on the camera when mounting the lens.
Do not mount the lens at an angle.
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
(DT 18-55mm F3.5-5.6 SAM, DT 55-200mm F4-5.6 SAM)
It is recommended that you use a lens hood to reduce flare and ensure
maximum image quality.
Fit the hood into the mount on the end of the lens barrel and rotate
the hood clockwise until it clicks.
A lens hood is not included with the DT 18-55mm F3.5-5.6 SAM. You can use
the ALC-SH108 (sold separately).
When storing, turn over the lens hood and place it onto the lens backwards.
Zooming
(DT 18-55mm F3.5-5.6 SAM, DT 55-200mm F4-5.6 SAM)
Rotate the zooming ring to the desired focal length.
Focusing
When using auto focus, the camera adjusts the focus automatically.
While the camera is focusing automatically, do not touch the rotating focusing
ring.
The camera’s direct manual focus function cannot be used with this lens. (Some
cameras do not have the direct manual focus function. If your camera has this
function, this restriction is explained in the section on focusing, in your camera’s
instruction manual.)
You cannot switch between AF/MF mode with the AF/MF button on the
camera. (Depending on the camera, the AF/MF button may not exist. If your
camera has this function, this restriction is explained in the section on focusing,
in your camera’s instruction manual.)
In MF (Manual Focus) mode, rotate the focusing ring while looking through
the viewfinder, etc. (See illustration .)
To switch AF (Auto Focus)/MF (Manual Focus) mode
You can switch between AF and MF with the focusing mode switch on the
lens. Make sure to set the focusing mode switch (lever) on the camera to AF.
Make sure to set the focusing mode switch to MF for manual focus. Do not
rotate the focusing ring without setting to MF. Rotating the focusing ring
forcibly without switching to MF may damage the focusing ring.
To shoot a subject at infinite distance in MF mode
The infinity position provides for some adjustment to compensate for focus
shift caused by change in temperature. When shooting a subject at infinity in
MF mode, focus by checking the viewfinder or other means.

Precautions on using a commercially available
exposure meter or manual flash shooting function
When shooting close to a subject with the DT 30mm F2.8 Macro SAM, the
brightness of the lens is reduced.
When shooting in automatic exposure mode or metered manual mode (for
example, the camera’s AUTO mode), the exposure is adjusted automatically.
When using a commercially available exposure meter or shooting with the
manual flash function available on some external flash units, set the exposure
higher than the indicated value.
