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.
This lens was developed jointly by Carl Zeiss and Sony Corporation and
designed for Sony A mount cameras. This lens is produced according to the
strict standards and quality assurance system of Carl Zeiss.
Notes on use
A
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
A
damage both.
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.

Precaution 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/
E
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 (Vario-Sonnar T 16-35mm F2.8 ZA SSM only).
Vignetting
When you use lens, the corners of the screen become darker than the center.
1
To reduce this phenomena (called vignetting), close the aperture by several
stops.

 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 dot on the lens (Lens
hood index). Turn the hood clockwise until the red dot 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.

 Zooming
Rotate the zooming ring to the desired focal length.
 Focusing
To switch AF (auto focus)/MF (manual focus)
The focus mode can be switched between AF and MF on the lens.
For AF photography, both the camera and lens should be set to AF. For MF
photography, either or both the camera or lens should be set to MF.
To set the focus mode on the lens (See illustration -.)
Slide the focus-mode switch to the appropriate mode, AF or MF.
In MF, turn the focusing ring to adjust the focus while looking through the

viewfinder, etc.(See illustration -).
To use a camera equipped with an AF/MF control button
( )
Press the AF/MF control button to switch AF to MF when both the camera and

lens are set to AF.
Press the AF/MF control button to switch MF to AF when the camera is set to

MF and the lens is set to AF.
Direct manual focus (DMF)
) MF( )
Rotate the focusing ring to set correct DMF when the focus is locked in AF-A
(automatic auto focus) or AF-S (single-shot auto focus).
) MF(
DMF is not available in the following cases:

)
– When the image is out of focus
– When AF-C (continuous auto focus) is selected
AF
– When the focus is confirmed for the second photo during continuous
recording in AF-A
Shooting at infinity in MF
 -  )
The focusing mechanism turns slightly past infinity to provide accurate
AF MF
focusing under various operating temperatures. Always confirm the image
sharpness through the viewfinder, etc., especially when the lens is focused
near infinity.
 )
Focus-hold button (See illustration –.)
While the focus-hold button is pressed, auto focus function is suspended and
AF
the focus is fixed for shooting.
The function of the focus-hold button can be changed on cameras with custom

MF AF
function capability. Refer to the camera manuals for details.
