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
AE
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).
AF
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 Merrill).
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 Merrill camera can automatically turn itself
off, if you do not operate it.
