Iso Sensitivity - Leica S2 Instructions Manual

ISO sensitivity

The ISO setting on the LEICA S2 allows the shutter speed/aperture
value to be adjusted to meet the requirements of the relevant
situation, in six steps.
The Pull 80 setting has an equivalent brightness to an ISO sen-
sitivity of ISO 80. However, pictures taken with 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 LEICA S2 also features the
Auto function 1 , in which the camera automatically adjusts the
sensitivity to the ambient brightness.
However, it is still possible to specify priorities when using this
function. This enables you to limit the range of sensitivities
used and also to set the shutter speed above which the auto -
matic increase in sensitivity is activated.
1 This function is not available when using flash units.

4. Select Set Maximum ISO and/or Set Maximum Exposure
Time in this submenu. Selecting Set Maximum ISO displays
a list of available values, while Set Maximum Exposure
Time opens a further submenu containing the 1/ f and
Manual Setting options.
5. In the Maximum ISO einstellen list, select the maximum
sensitivity to be used and thus the range within which you
want the automatic setting to work, or
5. in the Set Maximum Exposure Time submenu, select either
1/f if you want to leave it to the camera to ensure shutter
speeds that will prevent blurring, or Manual Setting.
With 1/f the camera only switches to a higher sensitivity if a
lower brightness would cause the shutter speed to fall below
the 1/f threshold, e.g. at speeds of slower than
70mm lens.
6. In the Manual Setting list, select the slowest shutter speed
you want to set (1/2s - 1/500s; in whole steps).
