45 mm F2.8

Thank you very much for purchasing a Sigma

Lens. In order to get the maximum performance

and enjoyment out of your Sigma lens, please

read this instruction booklet thoroughly before

you start to use the lens.

WARNING!! : SAFETY PRECAUTIONS

– Do not look directly at the sun, through the

lens. Doing so can cause damage to the eye or

loss of eyesight.

– Do not leave the lens in direct sunlight with-

out the lens cap attached, whether the lens

is attached to the camera or not. This will

prevent the lens from concentrating the sun’s

rays, which may cause a fire.

– The shape of the mount and its surrounding

parts are very complex. Please be careful when

handling them so as not to cause injury.

DESCRIPTION OF THE PARTS (fig.1)

1. Filter Attachment Thread

2. Focus Ring

3. Iris Ring

4. Focus Mode Switch

5. Mount

6. Lens Hood

7. Plastic Front Cap

8. Metal Front Cap

CAUTION

On cameras where lens aberration correction

is controlled with 'ON' or 'OFF' in the camera

menu, please set all aberration correction func-

tions to 'ON'(AUTO).

ATTACHING TO THE CAMERA BODY

Please refer to the camera’s instruction manual

for details on how to attach it to or detach it from

the camera body.

– On the lens mount surface, there are electrical

contacts. Please be careful with their handling

as scratches or dirt on them could cause mal-

functions or damage.

FOCUSING

For autofocus operation, set the focus mode

switch on the lens to the “AF” position (fig.2). If

you wish to focus manually, set the focus mode

switch on the lens to the “MF” position (fig.3).

You can adjust the focus by turning the focus

ring.

– Sudden temperature changes may cause con-

densation or fog to appear on the surface of

the lens. When entering a warm room from the

cold outdoors, it is advisable to keep the lens

in the case until the temperature of the lens

approaches room temperature.

– Please refer to camera’s instruction manual

for details on changing the camera’s focusing

mode.

IRIS RING

It incorporates an iris ring that is useful to adjust

the aperture value during Aperture Priority Auto

mode and Manual Exposure mode.

– With some cameras, the iris ring does not

work.

– Check the camera’s instruction manual for how

to adjust exposure.

FRONT CAP

In addition to the standard plastic front cap, a

metal front cap is available for better integration.

– This metal front cap is attached to the lens

using a magnet. Please do not put credit cards

(magnetic cards) or any other objects close to

the magnet on the metal front cap as it could

corrupt any data held on the object.

– The metal front cap cannot be used with a fil-

ter. When using filters, please use the supplied

plastic front cap.

LENS HOOD

A bayonet type detachable hood is provided with

the lens. This lens hood helps to prevent flare

and ghosted images caused by bright illumination

from outside the picture area. Attach the hood

and turn clockwise until it stops rotation (fig.4).

– In order to place the lens and hood into the

storage case, you must first remove the hood,

then replace it on the lens in the reverse posi-

tion (fig.5).

BASIC CARE AND STORAGE

– Avoid any shocks or exposure to extreme high

or low temperatures or to humidity.

– For extended storage, choose a cool and dry

place, preferably with good ventilation. To

avoid damage to the lens coating, keep away

from mothballs or naphthalene gas.

– Do not use thinner, benzine or other organic

cleaning agents to remove dirt or finger prints

from the lens elements. Clean by using a soft,

moistened lens cloth or lens tissue.

– This lens is not waterproof. When you use

the lens in the rain or near water, keep it from

getting wet. It is often impractical to repair the

internal mechanism, lens elements and electric

components damaged by water.

– The figures are for L-mount.

– The glass materials used in the lens do not

contain environmentally hazardous lead

and arsenic.
