Turning The Exposure Meter On/Off - Leica M Instruction Manual

TURNINg ThE EXpOSURE METER ON / OFF
The exposure meter is turned on by tapping the shutter release (16),
provided the camera is turned on at the main switch (15) and the
shutter speed dial (18) is not set to
The displays in the viewfinder or monitor light up continuously to
indicate that the exposure meter is ready:
– in aperture priority mode the LED display of the shutter speed,
– and in manual mode one of the two triangular LEDs in the
viewfinder lights up, either individually or in conjunction with the
center circular LED, while the light balance is displayed in the
monitor.
If you let go of the shutter release button without activating the
shutter, the exposure meter remains turned on for around 30s more,
and the relevant LED(s) remain lit for the same time.
If the shutter speed dial is set to
B .
B the exposure meter is disabled.
Notes:
• In aperture priority mode, if correct exposure cannot be achieved
using the available shutter speeds, the shutter speed display gives
a warning by flashing (only in the viewfinder, for more details, refer
to the "Aperture priority mode" section on p. 182).
• If the exposure meter reading is below the metering range in very
low lighting conditions and in manual mode, the left hand triangular
LED in the viewfinder flashes as a warning, or the left-hand bar of
the light balance flashes in the monitor. 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 in the viewfinder.
• 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 also prevents
pictures from being taken accidentally.
Note:
With many light sources (particularly LED and sodium vapor lamps),
alternating current causes fluctuations in brightness, which are
invisible to the eye. Because of the sensitivity and reading frequency
of image sensors, this can cause the monitor image to flicker or result
in strips in video recordings (not in photos). Selecting a slower shutter
speed can avoid the effect for the picture.
