ISO sensitivity

The ISO setting on the Leica S allows the shutter speed/aperture value to be

adjusted to meet the requirements of the relevant situation, in six steps.

As well as the ﬁxed settings, the Leica S also features the

Auto

function, in

which the camera automatically adjusts the sensitivity to the ambient bright-

ness.

However, when using the function it is also possible to specify priorities, for

example for compositional reasons. This enables you to limit the range of

sensitivities used and also to set the shutter speed above which the automat-

ic increase in sensitivity is activated.

Notes:

• In digital photography, the higher sensitivities generally result in an

increase in noise. This must be taken into account when thinking about

picture quality.

• For series exposures (see p. 36), bear in mind that the frame rates will be

slightly slower with higher sensitivities.

The function is not available when using ﬂash units.

Setting the function

1. In the

IMAGE menu (see p. 16/26), select ISO (5.9), and

2. call up the submenu. It contains the available ISO values and the

Auto

option.

To set the sensitivity manually

3. Select the desired value.

To set the sensitivity automatically

4. Select

Auto.

• A further submenu appears, containing three options

OK, Set Maximum

ISO

and Set Maximum Exposure Time.

To use unrestricted automatic setting

5. Select

OK in this submenu.

The automatic setting uses all sensitivities, as well as shutter speeds

between

s and

500

To restrict the automatic setting range

6. Select

Set Maximum ISO and/or Set Maximum Exposure Time in this sub-

menu.

• For

Set Maximum ISO a list of the available values appears, and for Set

Maximum Exposure Time

a further submenu appears containing the alter-

natives

1/f and Manual Setting.

7. In the

Set Maximum ISO list, select the highest sensitivity to be used and

thus the range in which the automatic setting will operate, or

8. in the

Set Maximum Exposure Time submenu, select either 1/f, if you want

to leave it up to the camera to ensure that shutter speeds that prevent blur-

ring are used, or

Manual Setting.

For,

1/f the camera only switches to a higher sensitivity if the shutter speed

would fall below the

threshold due to a lack of brightness, e.g. at slow-

er speeds than

s with a 70mm lens.

9. In the

Manual Setting list, select the slowest shutter speed you want to use

(

1/2s - 1/500s; in whole steps).
