ISO SENSITIVITY

In traditional photography, the choice of the ISO value

reflects the light sensitivity of the film used. Higher

speed films allow faster shutter speeds and/or smaller

apertures and vice versa, at the same brightness. The

ISO setting on the Leica M Monochrom covers a range

of ISO 320–10 000. Optimum reproduction quality

is achieved by using the a setting of

ISO 320. Higher

sensitivities result in an increase in picture noise.

This effect can be compared to the “graining” that

occurs with highly sensitive films. The Pull 160 setting

has the same brightness as a sensitivity of ISO 160.

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. The setting is made in

ISO increments, thus allowing delicate, targeted manual

adjustment of the shutter speed/aperture values to the

relevant situation.

In addition to the fixed settings, the Leica M

Monochrom also provides an

AUTO ISO function, in

which the camera adjusts the sensitivity automatically

to the ambient brightness. When used in conjunction

with aperture priority mode

(see p. 124), this

considerably extends the automatic exposure control

range, specifically by up to 4 aperture stops. 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 –

e.g. because of the noise mentioned above, and also

to set the shutter speed above which the automatic

increase in sensitivity is activated, e.g. to reliably

prevent blurred pictures.

The function is not available when setting the exposure manually

and when using flash units (always at

180

s).

Setting the function

1. Press and hold the

ISO

button (1.23).

• The possible settings appear in the monitor (1.32),

arranged in a grid.

2. While holding down the

ISO

button, use the setting

dial (1.29, forwards and backwards) or the direction

buttons (1.30, by row or column) to select the

desired sensitivity or the automatic setting.

Note:

When you release the

ISO

button, the list remains

visible for around

2s. Once the list disappears, the set value is applied.

If AUTO ISO is set, you can adjust the function to

your style of photography, or to your compositional

preferences

3. In the main menu (see p. 97/110), select AUTO ISO

Setup

(4.1.5), and

Max ISO and/or Slowest speed in the sub-menu.

This function requires the use of coded lenses (see p. 104).
