ExposurE METErIng

On the Leica M Monochrom, exposure metering for the
available ambient light is done through the lens with the
working aperture. The light reflected by bright shutter
diaphragm blades in the first shutter curtain is captured
by a photo diode and measured. This silicon photo
diode with forward­facing convex lens is positioned at
the center lower edge, on the camera base.
The speed / aperture combinations for a correct
exposure are specified by the viewfinder or monitor
displays or are determined with their assistance.
In aperture priority mode the aperture is selected
manually, and the camera then determines the
appropriate shutter speed automatically. In this mode, a
digital LED display indicates the resulting shutter speed
(e.g.
1000
)
If both values are set manually, a light balance made up
of three red LEDs (
) is used to correct the exposure.
When the setting is correct, only the central circular
LED is lit up.

TurnIng ThE ExposurE METEr on/oFF

The exposure meter is turned on by gently pressing the
shutter release button (1.19) to its 1st pressure point,
provided the camera is turned on at the main switch
(1.18) and the shutter speed setting dial (1.17) is not
set to

One of the displays in the viewfinder lights up
continuously to indicate that the exposure meter is
ready:
– In aperture priority mode, the digital LED display of
the shutter speed,
– and in manual mode one of the two triangular LEDs
lights up, either individually or in conjunction with the
center circular LED.
If you let go of the shutter release button without
activating the shutter, the exposure meter remains
turned on for around 12s more, and the relevant LED(s)
remain lit for the same time.
If the shutter speed setting dial is set to

notes:
• If the displays go out, the camera is in "standby"
mode.
• With very little ambient light, i.e. at the limits of the
exposure meter's range, it can take around 0.2s for
the LEDs to light up.
• In aperture priority mode, if the correct exposure
cannot be achieved using the available shutter
speeds, the shutter speed display flashes as a
warning (for more details, refer to the "Aperture
priority mode" section on p. 124).
• When making manual settings, if you are below the
exposure meter's metering range at very low light
densities, the left­hand triangular LED flashes as a
warning. In aperture priority mode, the shutter speed
is still displayed. If the required shutter speed falls
below the slowest possible setting of 32s, this display
also flashes.
• If the camera is out of use for an extended period
or is stored in a case, always turn it off at the main
switch. This prevents any power consumption,
including that which continues to occur in standby
mode after the exposure meter is turned off
automatically and the display is extinguished. This
also prevents pictures from being taken accidentally.

• For optimum pictures, we recommend making
sure that bright sections of the image are not
overexposed. This can be done very easily using the
clipping display (see p. 140).
