ISO SENSITIVITY
The ISO setting covers a range of ISO 320 – 12500 in
1
/
3
ISO
increments, and thus enables you to adapt the shutter speed/
aperture values to the relevant situation as required. In addition
there is the setting
Push 25000
that corresponds to a sensitivity of
ISO 25000.
As well as the fixed settings, the camera also features the
Auto 1
function, in which the camera automatically adjusts the sensitivity
to the ambient brightness and the shutter speed/aperture settings.
In conjunction with aperture priority mode (see p. 176) this
extends the range for automatic exposure control. A manual setting
provides more flexibility for using the desired shutter speed/
aperture combination.
However, when using the function it is also possible to specify
priorities, for example for compositional reasons.
Note:
Particularly at high ISO values and when editing pictures, noise as
well as vertical and horizontal stripes may become visible, especial-
ly in large, uniformly bright areas of the subject.
