10.5 Stop Down (Working Aperture)
With Stop Down, the working aperture / depth of field can be checked in the viewfinder.
Press the button B3 on the hand grip.
The aperture is set to the selected aperture value, and the aperture actually set in the
image is visible. As long as the button B3 is pressed, the aperture remains stopped down.
Background information: The image in the viewfinder is always displayed using full
aperture to ensure a better luminance. The aperture is set to the defined value (f-number)
when the shutter is activated. With the button B3 (Stop Down / Working Aperture), the
actual image exposure can be checked before the activation of the shutter.
In the display, the symbol for the working
aperture 1 appears in the hand grip display.

The depth of field is also indicated in the focus window at the lens, Æ chapter 10.2.2
“Focus indication at the lens”.
11 Exposure
11.1 Introduction
The exposure is determined by the exposure time (i.e. the shutter speed) and the aperture
value, and is influenced by the light-sensitivity of the material (ISO-standard).
To set the exposure in the image, three steps have to be performed:
• The definition of the light metering method for measuring the light conditions in
the image. The correct exposure value (EV) is the basis for the light metering
• The setting of the exposure mode, i.e. the combination of the shutter speed and
the aperture value
• The definition of the ISO-speed
