ISO SENSITIVITY

The ISO setting covers a range of ISO 200 – 6400 in
increments, and thus enables you to adapt the shutter speed/
aperture values to the relevant situation as required. The
setting has the same brightness as a sensitivity of ISO 100.
However, pictures taken using this setting have a lower contrast
range. When using this sensitivity setting, it is important to make
sure that important parts of the image are not overexposed.
As well as the fixed settings, the camera also features the
function, in which the camera automatically adjusts the sensitivity
to the ambient brightness and the shutter speed/aperture settings.
In conjunction with the aperture priority mode (see p. 146), 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,
especially in large, uniformly bright areas of the subject. Accord-
ingly, these features are identified by the suffix
The function is not available when using flash units.
