Sigma DP1 user manual Aperture Priority AE

A APERTURE PRIORITY AE

After you set the aperture, the camera will determine the appropriate shutter speed. If you select smaller apertures, depth of field will be greater. Larger apertures tend to blur the background, as depth of field will be shallower.

1

Set the Mode Dial to the A position.

(The aperture value indicator is illuminated in green.)

2

Select the desired aperture value by using button.

(The aperture value can be set in 1/3 stop increments from F4 to F11.)

3

Press the shutter button “half-way” to verify the focus and take the picture.

ξDepending on the selected aperture value, the camera automatically sets the shutter speed in following range.

Aperture	Shutter Speed
F4.0 ~ F5.0	15s ~ 1/1000s
F5.6 ~ F7.1	15s ~ 1/1250s
F8.0 ~ F9.0	15s ~ 1/1600s
F10 ~ F11	15s ~ 1/2000s

WARNING !!

ξWhen is shown on the color LCD monitor, camera shake may occur (the shutter speed is set slower than 1/25). If this mark is displayed, please use the flash (P.43, 44, 66) or a tripod.

ξIf the appropriate shutter speed is outside the range of suitable combinations due to the subject being too bright or too dark, the shutter speed indicator will blink. If the subject is too bright, set the aperture value to a smaller one (larger F-number). If the subject is too dark, set the aperture value to a larger one (smaller F-number) until the indicator stops blinking.
