Exposure control
The LEICA CM offers you a choice of two modes for controlling the exposure, which you can use to adjust the camera perfectly to
your preferred working method or the relevant subject. You can choose between fast, convenient and reliable program mode, i.e. ful-
ly automatic, and aperture priority mode, for easy specification of the desired depth of field.
Programmed automatic exposure control mode
Programmed automatic exposure mode is the right mode to choose for uncomplicated photo-
graphy. It is ideal when you want the camera to be ready to use at all times, particularly for quick
snapshots or for moving objects, i.e. when there is no time to make individual settings. It controls
the exposure by automatically setting an appropriate combination of shutter speed and aperture.
To make the setting, turn the lever 10 clockwise as far as it will go, until it engages in the position
marked P.

When the shutter release button is pressed to the pressure point, the speed and aperture values set by
the camera appear alternately.
The display disappears immediately when the shutter release button is released, otherwise after 4s, i.e.
after both values have been displayed 3x.
If the available brightness exceeds the working range of the exposure control system, this is indicated
by a flashing .
In the modes with slower shutter speeds and those with no flash (see “Selectable modes”, p. 89), the
camera automatically switches to long time exposure (

) at low brightness. This is indicated by the alter-
nating display of (for the largest aperture) and (representing exposure times >30s) before the
