Iso Sensitivity - Leica S Instructions Manual

EN

ISO sensitivity

The ISO setting on the Leica S allows a manual adjustment of the shutter
speed/aperture values to the needs of the particular situation.
As well as the fixed settings, the Leica S also features the
tion, in which the camera automatically adjusts the sensitivity to the
ambient brightness. When using the function, however, it is also possible
to specify priorities, for example for compositional reasons. You can both
limit the range of sensitivities used and set the shutter speed below
which the sensitivity is automatically increased.
Notes:
A general rule of thumb is digital photography is that higher sensitivities
result in increased noise. This has to be taken into consideration for the
expectations on the picture quality.
Note with picture series that the frame rates decrease with higher sensi-
tivities.
1 The function is not available when using flash units.
