You will find information on using lens in this manual. Precautions
common to lenses, such as notes on use will be found in "Precautions
before using"
on aseparate 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
Sonya mount cameras (models equipped with APS-
esized image sensor). You cannot use on 35mm-format cameras.

•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 ofthe lens that protrudes when focusing.
Precautions for flash use
•When using abuilt-in camera flash, make sure to shoot from at least 1m (3.3
feet) away from your subject. With certain oflenslflash combinations, the lens
may partially block the light
of the flash, resulting in ashadow at the bottom of
the picture.
•When using the Ring Light' or Macro Twin Flash
Kit*, use the Macro Light
Adaptor'.
•Ring Light,
Macro Twin Flash Kit and Macro Light Adaptor are sold
separately.
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 Ito 2stops.

m Attaching/detaching the lens
To attach
the lens (See illustration ID-[I].)
1Remove 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).
2Align 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 ID-C2J.)
While pressing and holding the lens release button on the camera,
rotate
the lens counterclockwise until it stops, then detach the lens.
[!J 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 th~ 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 to focus. (See illustration [!].)
•The focus signal in the Viewfinder indicates the current degree of fOCUSing.
To switch AF {Auto Focus)/MF (Manual Focus) mode
You can switch between AF (automatic focus) and MF (manual focus) 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 asubject at infinitedistance in MF mode
The infinity position provides for some adjustment to compensate for focus
shift caused by
change in temperature. To shoot asubject at infinite distance
in MF
mode, use the Viewfinder and set focus.

*' 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 adistance encoder. The distance encoder allows more accurate measurement (ADI) by using aflash 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.
