consult with Sigma- authorized service personnel. If you see fingerprints on the

glass portion of the dust protector, first use a blower to remove any dust, then

gently wipe it with a soft, clean cloth.

EXPLANATION OF TERMS

Auto Exposure; by using a built-in exposure meter, camera determines the

correct exposure value, which is combinations of shutter speed and/or aperture

value.

AE Lock

The camera will fix and memorize the exposure value with AE lock. For example,

if a photographic subject is placed in the center and exposure value of the

composition is fixed, the brightness of the background will not influence the

exposure, even if the composition changes and the subject is moved from the

center of a screen. (AE lock button must be used).

Auto Focus; by using a built-in sensor, camera adjusts the focusing automatically.

AF Lock

In AF shooting mode, you can lock the focus on the main subject. For instance,

compose the desired subject in the center of the viewfinder. With the focus fixed

at the same setting, you can re-compose the picture with the subject off-center

and take shots. (Please press the shutter button halfway to use this feature with

Sigma SD1).

Aperture

The lens opening of the iris diaphragm inside the lens. The amount of light, which

strikes the image sensor, is adjusted by the iris diaphragm. The f-number (Focal

Length/Diameter of the Aperture Opening) describes the size of this opening, the

size of the hole can be made larger or smaller. Large aperture (low f-number)

gives bright results and, small aperture (high f-number) gives darker results.

Auto Power-Off

For saving the battery power, the SD1 camera can automatically turn itself off, if

you do not operate it.
