COMBINATIONS (SHIFT)
Changing the preset values using the Shift function combines the 

security and speed of fully automatic exposure control with the 

freedom to adjust the speed/aperture combination selected by the 

camera to your own preferences at any time.

For faster speeds, e.g. for sports shots, turn the thumb wheel 23 to 

the left, for larger depth of field, e.g. for landscape shots turn it to the 

right (provided you are prepared to accept the slower shutter speeds 

that this entails)

• Shifted values are indicated by an asterisk next to the shutter 

speed or the aperture.

The overall exposure, i.e. the brightness of the image, remains 

unchanged. To guarantee correct exposure, the adjustment range is 

limited.

To prevent accidental use, after each picture and also if exposure 

metering is automatically turned off after 12s, the values revert to 

those set by the camera.

APERTURE PRIORITY - A
Aperture priority mode sets the exposure automatically according to 

the manually selected aperture. It is particularly suitable for pictures 

where the depth of field is the critical compositional element.

With a correspondingly low aperture value, you can reduce the depth 

of field range, for example to "release" a face fully in focus from an 

unimportant or distracting background in a portrait or, conversely, 

you can use a higher aperture value to increase the depth of field 

range so that everything from the foreground to the background is in 

focus in a landscape shot.
Taking a picture in this mode:

1. 

Turn the shutter speed setting dial (11) to the 

A

 position

• The set aperture value is displayed in white.

2. 

Set the desired aperture value with the corresponding dial (10)

3. 

Press the shutter button (8) to the pressure point

• The automatically calculated shutter speed is displayed in 

white. If even the slowest or fastest shutter speed combined 

with the set aperture results in under or overexposure, both 

values are displayed in red.

If the automatically set shutter speed appears to be appropriate for 

the intended composition:

4. 

Push the shutter button all the way down to take the photo

If not, you can change the aperture value before taking the picture.
