using the lens.
This lens is designed for A-mount which can be used on Sony α cameras
(models equipped with APS-C sized image sensor). You cannot use on

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
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.
Precautions for flash use
When using a built-in camera flash, make sure to remove the lens hood and
shoot from at least 1 m (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 a built-in camera flash is used, the corners of the screen may appear
darker at wide-angle position. Check the focal length according to the built-in
flash on your camera.
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
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.
Minimum focus is the 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.

Attaching/detaching the lens
To attach the lens (See illustration –.)
Remove the rear and front lens caps and the camera body cap.
You can attach/detach the lens front 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.
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
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.
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.
Rotate the zooming ring to the desired focal length.
When using the auto focus, the camera focuses the lens automatically.
Even when the auto focus is set, the focusing ring may rotate if you move it
unintentionally. Only rotate the focusing ring manually when the camera is
set to the direct manual focus, otherwise a malfunction may result. (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
When focusing manually, set your camera to the manual focus and rotate the
focusing ring while looking through the viewfinder, etc.
